Material selection determines several aspects of a metal fabrication project, such as cost, ease of manufacture, functionality, and overall durability.
Since metals differ significantly in terms of strength, resistance to corrosion, machinability, and accessibility, a material that’s perfect for one project may be unsuitable for another.
By realizing how material properties can help or harm a project, your team can avoid costly reworks and thus guarantee that the material you choose will perform as intended in the real world.
What Role Does Material Strength Play in Part Performance and Safety?
Strength refers to a metal’s ability to resist tension, compression, impact, and repeated stress.
It’s important to compare the strength of metals during the early stages of product design. This is because the strength of the metal has to match the most likely stresses that will exert their force on it.
For instance, you may need to use high-strength steel or heat-resistant metals for industrial equipment, chassis designs, or heavy-duty structures. But in the case of consumer products or building applications, aluminum or mild steel may be the best option.
Working with a partner who understands the strength requirements for different metal fabrication projects can help you avoid the negative effects of overspecification.
When Does Weight Become a Critical Factor in Metal Fabrication?
Weight considerations come into play when considering factors such as mobility, transportation costs, installation, ergonomic factors, or structural load limitations.
For example, in automobile, or electric product assembly, using lightweight metals like aluminum or certain titanium alloys will lead to quicker handling, higher efficiency, and simplified installation.
Meanwhile, carbon steel and stainless steel will provide the necessary rigidity and impact resistance that are essential for foundations, structural supports, and industrial components.
Fabricators carefully weigh the pros and cons of using light metals against those of using heavy metals for their production.
Why Is Corrosion Resistance Necessary for Some Environments?
Corrosion resistance is a metal’s capability to resist the effects of water, chemicals, salt, or temperature changes.
In harsh environments, such as marine engineering, water systems, agriculture, and food processing, metals like stainless steel, aluminum, copper alloys, or galvanized steel allow for longer product life cycles.
Even though these more resistant metals may have a higher price initially, they’re less susceptible to rust, wear, or degradation. Therefore, a metal that lasts longer in a demanding environment will result in fewer downtime costs.
Who Benefits the Most from the Use of Highly Machinable Metals?
Both manufacturers and end-users benefit significantly when a project meets the machinability requirements. Machinability influences the cutting speed, tool wear, accuracy, and labor requirements.
When projects require very tight tolerances or consistent precision, the usual practice is to compare the machinability of steel and aluminum to estimate labor and lead times.
For example, metals such as aluminum, 300-series stainless steel, and mild steel are highly machinable, which helps accelerate production and reduce tooling costs.
Materials like titanium or tool steels are tougher, making them a viable choice for high-performance settings. However, they do require special equipment.
Ultimately, machinability has a great influence on production speed, labor costs, and the precision of fabrication.
How Does Availability Affect Metal Pricing and Scheduling?
Availability is another factor in custom fabrication that affects material cost, lead time, and the reliability of the supply chain. Generally, more standard metals, like 300 series stainless steel, mild steel, or common aluminum alloys, offer reasonably stable prices and availability.
On the other hand, special alloys, limited-production metals, or unusual thicknesses can significantly increase procurement time.
Using these types of metals in custom fabrication projects can lead to increased delays, but may be necessary.
How Does Weldability Influence the Final Product and Fabrication Workflow?
Weldability refers to the extent to which a fabrication team can join metals together without encountering problems such as cracking, warping, or requiring excessive finishing work.
For example, mild steel and stainless steel are highly weldable materials, whereas aluminum is somewhat more challenging to work with.
Knowing the properties that affect a metal’s weldability, you can pick the right alloys that fit the fabrication process without adding time or complications to the workflow.
What Are the Cost Benefits of Matching the Right Metal with the Right Application?
Top performers lose no more than 0.6% of their revenue to scrap and rework. For others, it’s nearly 2.2%, a difference that can amount to millions of dollars every year.
This is why choosing the right material is so important. It minimizes waste and reduces the need for reworking. It also enables smoother processes when cutting, machining, welding, and assembling.
For example, they may help you discover a more affordable metal that provides performance similar to a higher-priced alloy, which helps you avoid overspending.
Furthermore, if you align material properties with the component’s working conditions, you can increase its longevity and control custom fabrication costs.
Who Has the Most Significant Role in Leading Smart Material Decisions?
An experienced fabrication partner can help you choose metals that meet performance needs without increasing costs.
Experts in this area consider various aspects of real-world applications, such as thermal expansion, environmental exposure, finish requirements, and anticipated load cycles.
They also rely on a metal selection guide specifically designed for manufacturers, which contains comparisons of metals based on weldability, machinability, weight, tensile strength, and corrosion resistance.
With a knowledgeable fabrication partner by your side, your sheet metal fabrication team can utilize the most suitable alloy for each component, ensuring optimal performance.
What Long-Term Results Come from Better Material Planning?
Better material planning leads to improved accuracy, efficiency, and consistency of production output. Additionally, by carefully selecting metals, the projects can proceed without interruption.
The chance of material failures, product recalls, and warranty claims will drastically decrease. Rather than considering careful material planning as an additional expense, you can think of it as a contribution to the long-term performance and value of the final product.
