5052 has the highest strength alloy of the non-heat treatable grades and offers high workability, strength, corrosion resistance, and it can be easily welded. It has good resistance to marine atmosphere and salt water corrosion. With excellent workability it can be easily drawn and formed into intricate shapes.
6063 an aluminum alloy, with magnesium and silicon as the alloying elements, is the most common alloy used for aluminum extrusion. Heat treatable and weldable, 6063 allows complex shapes to be formed with very smooth surfaces for a variety of exterior and interior architectural applications.
Aluminum alloy 6262 is a heat treatable alloy with very good corrosion resistance and strength. Additions of bismuth and lead help to lubricate the cutting tool giving it excellent machinability and surface finish.
Aluminum alloy 7050 has high strength at subzero temperatures. However, their strength can be reduced at high temperatures. 7050 is heat treatable so as to produce mechanical properties of high strength and toughness. It has very good resistance to stress corrosion cracking. Commonly used in the manufacture of aircraft and other structures.
