6262

Grade 6262 aluminium is a heat treatable alloy with additions of copper, lead, silicon, magnesium and bismuth. The addition of lead and bismuth impart the excellent machinability of grade 6262. While the magnesium, copper and silicon combine to enhance the mechanical strength and corrosion resistance of the alloy. The 6262 aluminium can be hardened by cold working or by a combination of aging and subsequent cold working.

As a result of its machinability either high-speed steel or carbide tooling can be used to obtain smooth surface finishes (light cuts may be possible without lubrication). In turn the excellent finish of machined parts allows the material to be anodised with ease. Grade 6262 can also be used in place of 2011 when higher corrosion resistance and better anodising response is required.
