Steel vs aluminum processing is one of the most important considerations OEMs faces when evaluating materials for a new product or production program. Material selection affects manufacturing costs, product performance, supply chain reliability, and long-term scalability. While both metals are widely used across industries, each offers distinct advantages and processing requirements. Choosing the wrong material, or the wrong processing partner for it, can mean redesign delays, blown budgets, or a supply chain that can’t scale with production.

For many OEMs, the decision extends beyond simply choosing the lighter or stronger option. Processing capabilities, lead times, availability, and downstream manufacturing requirements must also be considered. As a result, understanding the differences between steel and aluminum can help procurement teams, engineers, and operations leaders make more informed sourcing decisions.

Understanding Steel and Aluminum in Manufacturing

Steel and aluminum are among the most used industrial metals. However, their physical properties create significant differences throughout the manufacturing process.

Steel is valued for its strength, durability, and cost-effectiveness. It is widely used in automotive, construction, heavy equipment, appliance, and industrial applications where structural performance is critical.

Aluminum, on the other hand, offers a high strength-to-weight ratio and natural corrosion resistance. Consequently, it has become increasingly popular in transportation, aerospace, and automotive applications focused on weight reduction and fuel efficiency. The growing use of aluminum applications in automotive manufacturing continues to drive demand for specialized processing capabilities.

For OEMs evaluating aluminum vs steel manufacturing, understanding how these materials behave during processing is just as important as comparing their end-use properties.

Comparing Steel vs Aluminum Processing Requirements

Although many service center operations are similar, several key differences exist when processing steel and aluminum.

Formability and Material Handling

Aluminum is generally easier to form than many steel grades. However, it can be more susceptible to surface damage during handling and transportation. Therefore, additional care is often required throughout the supply chain.

Steel typically offers greater resistance to handling damage. Nevertheless, higher-strength grades may require increased forming forces and specialized tooling.

As a result, OEMs should evaluate both manufacturing requirements and downstream handling considerations when selecting a material.

Slitting, Blanking, and Precision Processing

Both materials can be slit and blanked to precise tolerances. However, tooling, […]

Reduce metal processing costs by identifying the hidden inefficiencies that impact production every day. For many OEMs, operational losses are not caused by material pricing alone. Instead, scrap, downtime, inconsistent processing, and logistics delays often create larger long-term expenses. At the same time, manufacturers are being pushed to improve margins while maintaining quality and production speed. Because of this, manufacturing cost optimization has become a major focus across industrial operations. Processing and supply chain solutions are designed to help manufacturers improve efficiency while lowering operational costs. Understanding where losses originate is the first step toward building a leaner, more profitable operation.

Hidden Processing Costs Add Up Quickly

Many manufacturing inefficiencies begin before production even starts. Poor coil quality, inconsistent tolerances, delayed shipments, and unnecessary handling can all increase operational costs over time.

For example, improperly processed material may lead to:

Increased scrap rates
Longer machine setup times
Faster tooling wear
Production slowdowns
Additional quality inspections

Individually, these issues may seem manageable. However, when they occur consistently, profitability can be affected significantly. Therefore, metal processing cost reduction strategies are now being prioritized by manufacturers focused on long-term efficiency.

According to the National Institute of Standards and Technology, operational efficiency and supply chain optimization remain critical for improving manufacturing competitiveness.

Scrap Reduction Starts with Better Material Processing

Scrap reduction metal processing efforts often begin with incoming material quality. If steel or aluminum arrives with poor flatness, edge defects, or inconsistent dimensions, production efficiency can quickly suffer.

Processes such as precision slitting, leveling, and cut-to-length processing are used to improve material consistency before fabrication begins. As a result, equipment performance can be improved while unnecessary downtime is reduced.

In many facilities, steel processing efficiency depends heavily on how material is prepared upstream. Better coil processing helps reduce stoppages, minimize rework, and improve throughput across production lines.

Likewise, aluminum processing savings are often achieved when lightweight materials are processed to tighter tolerances before stamping or forming operations begin. Consequently, manufacturers can reduce waste while maintaining faster production speeds.

Metals and Steel History: From India and Europe to Modern America

maria2022-08-05T16:32:28+00:00May 4th, 2022|News Blog|

Iron, the Herald of Things to Come

Metals and steel history spans from India and Europe to modern America. For the ancients, much of life was a mystery. At first, humans only utilized the easy-to-find metals, such as gold, silver, and copper, that didn’t require human intervention to become a final product. Other available metals needed treatment before they could be used. For example, smelting was needed to extract iron from iron ore, which is a chemical compound formed from iron and oxygen. Altogether, prehistory was an age where humanity was at the mercy of the colossal powers that govern the universe.

Even still, humans progressed.

A philosopher named Aristotle perceived the essence of virtue. He theorized that virtue lies at the balance point between deficiency and excess.

“The man who shuns and fears everything and stands up to nothing becomes a coward; the man who is afraid of nothing at all but marches up to every danger becomes foolhardy.” — Aristotle

Aristotle would have recognized steel as a virtuous metal. Steel contains anywhere between 0.05% to 0.25% carbon content, the perfect balance between deficiency and excess. Too little carbon and the metal becomes weaker and soft. Too much carbon and the metal will become brittle.

But getting metal to show its virtue as steel would take technological processes that defied humans for many years. While they used bronze, many civilizations neglected iron because iron technology at the time could only produce a “low-density, sponge-like material.” The main obstacles to higher quality iron were designing furnaces with high enough temperatures and the lack of basic knowledge of elements. Eventually, however, the abundance of iron ore (more abundant than the tin needed to make bronze) made it the metal of choice. This discovery began the Iron Age. With the advent of the Iron Age, steel, an alloy of iron, now found itself in ideal circumstances to surface as the supreme metal. However, steel would have to wait until after the industrial revolution to be mass produced.

To make steel, all that’s needed is a bit of charcoal, iron, and a furnace. However, the smelting can be tricky. If “your gangue is ‘wrong’, your bellows are leaky or especially efficient, your charcoal is too reactive, […] all you produce is slag, useless cast iron, or small useless blooms.” So much mystery shrouded steelmaking, that ritual and religion often got mixed up with science. One superstitious smith in the Middle Ages insisted on “quenching the steel in ‘the urine of a redheaded boy‘.”

Humanity would eventually conquer the process over centuries. Now, we will try to follow the oftentimes obscure history of steel technology.

An Abbreviated History of Steel

Egyptians, Hittites, and the Earliest Known Steel-work

The mighty Egyptians don’t need an introduction. They are the builders of pyramids and the Sphinx, of making papyrus and hieroglyphics, appear prominently in much of the Old Testament, and are well represented in museums across the planet. However, in steel lore, Egyptian […]

Steel Processing at National Galvanizing

andre2020-09-30T19:24:37+00:00September 30th, 2020|News Blog|

Today, modern chemists must face the same problem that one element posed to the Egyptians thatshould have destroyed the pyramids. It’s that ubiquitous element that threatens everything made by humans: water. As frost formed inside the stone structure at night and expanded with the morning, slow cumulative damage should have been done to the pyramids. For many years, this mystery defied the explanation of archeologists, however was eventually solved. A detailed study concluded that ancient Egyptians relied on technology to defy the power of water: they had invented a primitive form of cement.

Water threatens the integrity of modern structures. Steel, the very backbone of modern civilization, rusts when it comes into contact with water. Technology has been the answer for modern man, just as it was for the pyramid builders. Various techniques have been developed to prevent steel from corroding. One of the most sought after by leading industries is galvanizing. Both long-lasting and cost-friendly, galvanized steel can resist rust for 70 years or more. The characteristics of the environment where it is used, and the thickness of the protective coat can influence the lifespan of the steel. Today, a sophisticated process known as hot-dipping is used to galvanize steel. Essentially, galvanizing adds a zinc-iron coating to the metal, forming a protective layer. The multi-step process described below gives galvanized steel its protective qualities:
1) The steel is cleaned in a degreasing solution.
2) After being cleaned, the steel is pickled by running through various tanks containing hot sulfuric acid.
3) The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride).
4) After the flux, the steel is galvanized through immersion in a vat of molten zinc.
5) Afterward, the steel is inspected for consistency and a complete coating.
Galvanized steel has a low, initial cost, and no need for maintenance. It also provides other important advantages:
• Rust resistance: The iron elements in steel are incredibly prone to rusting, but the addition of zinc acts as a protective buffer between the steel and any moisture or oxygen.
• Easy inspection: It is easy to tell how strong a galvanized coating is just by looking at it. There are also quick stress tests that can determine how thick the zinc coating is.
• Sacrificial anode: This ensures that any damaged steel is protected by the surrounding zinc coating. It does not matter if the steel section is completely exposed; the zinc will still corrode first.
• Longer life: With galvanization, a piece of industrial steel is expected to last 70 years in average environments and can last over 20 years with severe water exposure. No maintenance required.
Galvanization is part of a larger framework in steel preparation. Clients can benefit through facilities that can apply various processes to steel including hot-dipped galvanizing. That’s why National Galvanizing’s state-of-the-art facility enables pickling, galvanizing, galvannealing, and slitting, all in one location. As a joint venture between National Material L.P. and Heidtman Steel, National Galvanizing has an unparalleled structure for quality, high-speed supply that serves the automotive, heavy truck, agricultural, garage door hardware, and HVAC industries, among others.
