Sheet metal is a widely used form of raw material, usually 0.006 and 0.25 inches thick sheet used in sheet metal fabrication. Use the sheet metal gauge chart on our site to designate the thickness. Here are some popular sheet metal materials, stainless steel grade 304 is one of the most common options due to its good corrosion resistance, formability and weldability. If your applications are pumps, valves, chemical equipment, and marine product, grade 316 is recommended. For aluminum, the four most common aluminum grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6. Brass is also widely used in the sheet metal fabrication process, it has more strength, corrosion resistance, and formability when compared to copper while retaining its conductivity.
