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.
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.
6061-T6511 is a screw machine alloy that has superior corrosion resistance and anodizing features and is one of the most commonly used aluminum alloys due to its numerous characteristics. It is generally selected where welding or brazing is to be performed and is also used extensively in forging applications.
Popularly known as “the aircraft alloy”, 2024 has higher properties than 2011 or 2017 an is largely used for aircraft fittings. It is widely used for all types of threaded fasteners because of its relatively higher shear strength.
