be is extremely useful at low-temperatures. At subzero temperatures its strength increases while retaining ductility. At temperatures over 400F aluminum alloy sheets tend to lose some of their strength.
Aluminum, like Stainless Steel, iscorrosion resistant. It is, however, much lighter and softer than Stainless and Carbon Steel. To prevent the dull appearance that results from the oxidation of the outer layer, Aluminum can be either clear or color anodized after perforating. Unlike paint or powd
