Material Properties and Corrosion Resistance

When it comes to sheet metal fabrication, material properties play a vital role in determining the performance and durability of the final product.

Corrosion resistance is one of the most critical factors to consider, as it can significantly impact the part’s lifespan. Different types of sheet metal offer varying degrees of corrosion resistance, making it essential to choose the right material for the specific application.

Understanding the specific corrosion resistance properties of each material helps in selecting the right sheet metal for the job, ensuring the longevity and reliability of the fabricated parts. Additionally, powder coating can be applied to create a visually appealing, durable, and corrosion-resistant layer that enhances the part’s aesthetics.

Environmental Considerations in Material Selection

Recycled steel and aluminum are excellent alternatives to traditional materials. They offer a reduced environmental impact without compromising on performance. These materials help conserve natural resources and reduce the carbon footprint associated with manufacturing processes.

Additionally, materials like stainless steel and galvanized steel provide excellent corrosion resistance, ensuring longevity and durability in diverse applications. Tool steel, known for its exceptional hardness and resistance to abrasion, is also a preferred choice for manufacturing tools like punches and blades, although its brittleness limits its suitability for certain metal forming processes.

Stainless steel, with its high recyclability and long lifespan, is a sustainable choice for many industries. Galvanized steel, with its protective zinc coating, offers enhanced corrosion resistance, making it suitable for outdoor and industrial applications.

Industry Applications of Sheet Metal Fabrication

The landscape of materials within the manufacturing industry is immense, and sometimes it might be intimidating to select the proper material for your sheet metal fabrication project. With sheet metal fabrication experiencing diverse technological advances and innovations, you must also adapt to the latest trends by making an investment in the proper material to serve your needs. To better understand why the material choice plays a significant role, you should be aware of specific factors before selecting a material. Once you go through these factors, you can link them to your goal and product to decide which material will be the best option for your sheet metal prototypes. This article guides you through the most significant factors you must bear in mind when choosing the sheet metal material for your prototype. Therefore, if you’re interested in learning how to select your materials for sheet metal fabrication, continue reading ahead.

Consider The Material’s Hardness

Hardness relates to the metal’s capability to withstand deformation in case of impact, load, or abrasion. Hardness can be measured based on its resistance to indentations, scratches, and bounces. Besides, certain issues with hardness are possible to overcome through a hardening process. Hardness is crucial for load-bearing constructions because hard metals are better at withstanding abrasion and load. Metals with high levels of hardness are titanium, bronze, hot rolled steel, spring steel, stainless steel, brass, and cast iron. On the contrary, metals with low hardness are copper, aluminum, and lead.

Purpose And End Use

You need to always begin with having clear objectives and views on how your product will be used. Once you get a new point of view and re-envision your metal products, you may even enhance your product’s lifetime. Furthermore, think about the other components your parts will interact with,  and the conditions your sheet metal prototypes will be placed under for use.

Shape And Geometry

With all the technological advances in the manufacturing sector, various materials are easily adjustable. So, think if your prototype will require basic bends or complex linear forms. Examine and learn the qualities and characteristics of varied materials such as aluminum, steel, stainless steel, brass, copper, lead, and brass.

Discover which material and procedure go well together in order to achieve your expected results. Some types of sheet metal are easier for bending over others. For example, the majority of aluminum grades are very pliant. The advantage of a material that’s easily pliable is that it gives you the possibility to combine separate parts. In fact, you may replace screwing or welding. It will reduce piece count and ease assemblage.

Corrosion Resistance

When choosing a material, you should consider the conditions it’ll be exposed to once placed. Some metals react better than others to oxidation, water, or other elements. For example, metals such as stainless steel won’t erode, but they may develop an oxide layer. You should also take into consideration that galvanic corrosion may happen when different metals are in contact together. Metals that are less corrosion resistant are cold-rolled carbon steel, copper, aluminum, stainless steel, titanium, nickel, and tin.

Requirement & Run Length

You have to think of the impact of the preliminary cash flow management and the long-term ROI (return on investment) offered by the material you choose. Make the necessary calculations and look into the approximate yearly units you will need, and if the material you pick will balance the return on investment. Tooling expense amortization can provide you the best investment return. Consequently, take into account that aspect likewise prior to zeroing in on materials.

Size of The Prototype

Depending on the size of the prototype you want to fabricate, know that each technique can fabricate a specific amount of metal length. For instance, roll-forming enables you to fabricate pieces as far as 16 meters in length. So, examine the size of your sheet metal prototypes, particularly the length of the part. Afterward, according to that criteria, select the proper material and the technique as well.

Think about the Cost for the Material Beforehand

Cost generally isn't the most significant factor when choosing a sheet metal for fabricating a prototype. It’s crucial to make the best selection based on the factors we’ve listed above. However, if there is a valid alternative with a lower cost, it’s always worth considering. Still, bear in mind that many times lower cost materials need additional processing, which can result in you not, in fact, saving a lot, so you could have used the higher cost material in the first place. High price metal is stainless steel, and low price metals hot rolled steel, low carbon steel, and tin.

Why Material Choice is Important

These factors we mentioned above will enable you to exclude other material options while making your selection and choose the material which suits the most for your products or parts. The material choice is significant because metals behave differently to different surroundings and conditions. That involves actions like, for instance, cooling, heating, cooling, molding, and melting. For that reason, most of all, the choice of material matters in sheet metal fabrication projects. Selecting the best material for your parts will provide you with a competitive advantage by improving factors like quality, mechanical properties, endurance, function, and performance. The chosen material needs to be able to sustain its strength and physical features during the process of manufacturing. If you don’t select the proper metal, your product will probably fail during the manufacturing procedure.

Final Words

Selecting the right material for your sheet metal prototypes will provide your product many benefits and improve its overall quality, function, and performance. If you overlook choosing the right material, the chances of prototype failure during the manufacturing process are high. Therefore, evaluate our guide before you begin with your sheet metal fabrication project because the factors we listed above can help any manufacturer select the correct metal.
