alloy containing traces of lead and bismuth.It has good machinability and corrosion resistance,
and most of them are extruded and drwan tubes, rods, profiles and wires.6262сorrosion resistant fast-cutting alloy, having the same strength as 6061, is applied to threaded high-stres mechanical
parts that require corrosion resistance better than the 2011 and 2017 alloys.Such as lens body.，gasifier parts, brake parts, gas appliance parts.
The 6262A is optimized on the 6262 composition,using the Sn element to replace the heavy
Metal Pb,which meets the EU ROHS environmental requirements and has the same
characteristics as the 6262 aluminum alloy.
