Coil: 0.3mm-3.0mm

Sheet: 0.3mm-300mm

Width: 50mm-2000mm

Standard: ASTM, AMS, BS etc.

1050A is a commercially pure wrought aluminum grade containing at least 99.50% aluminum. It combines excellent corrosion resistance, high ductility and good electrical and thermal conductivity. Sheet is readily bent, drawn and welded, making it useful for fabricated enclosures, reflective surfaces and heat transfer components. Strength increases through cold working rather than precipitation heat treatment. Its low strength and relatively poor machinability favor formed sheet applications over highly loaded precision parts.
