Aluminum Vs Stainless Steel: Which Is Better For Metal Fabrication?
In aluminum vs stainless steel fabrication work, knowing which material is better suited for an application is essential for a successful outcome of a given project. Here, GLORY Machinery Equipment, a leading metal sheet fabrication manufacturer & supplier with OEM & ODM service discusses the basics of each material and their key considerations for use in metal fabrication.
Basics of Aluminum:
Aluminum is a silvery-white, soft, nonmagnetic, ductile metal. It has good electrical and thermal conductivity, low density, and can be easily worked and machined. Aluminum is used in a wide variety of applications, including cookware, food packaging, electronics, aircraft parts, siding and gutters, among others.
Basics of Stainless Steel:
Stainless steel is an alloy of iron, chromium, nickel, and other metals. It has a shiny, lustrous appearance and is corrosion resistant. Stainless steel is used in a wide variety of applications, including kitchen utensils, medical devices, architecture, and more.
Aluminum vs Stainless Steel Considerations:
Strength
Aluminum is about one-third the density of steel and is much weaker than steel. Stainless steel is stronger than aluminum but not as strong as wrought iron.
Electrical and Thermal Conductivity
Aluminum is a better conductor of electricity than stainless steel but a worse conductor of heat. Stainless steel is a better conductor of heat than aluminum.
Thermal Properties
Aluminum has a lower melting point than stainless steel and will become liquid at a lower temperature. Stainless steel has a higher melting point and will remain solid at higher temperatures.
Weldability
Aluminum can be welded using any method, but it is more difficult to weld than stainless steel. Stainless steel can be welded using any method, but it is more difficult to weld than aluminum.
Cost
Aluminum is less expensive than stainless steel.
Specific Industries:
Aluminum is used in the aerospace industry and for other applications where weight is a concern. Stainless steel is used in the food and medical industries because of its resistance to corrosion.
