Alloy 6020: A Lead-Free Aluminum Alloy Featuring “A” Rated Machinability

In 1990, the development efforts at ALCOA's Massena Operations began with the objective to create a free machining alloy that would be comparable to a lead bearing alloy, 6262, in strength, machinability, corrosion resistance, anodizing, brazing, and welding responses while eliminating the health and environmental concerns associated with lead. The results from years of controlled experimentation was a 1996 patented and registered 6020 alloy (nominal 1.1% Sn addition) which proved all of the objectives were met and the machinability performance was enhanced over the “B” rated 6262 product. Proclaimed as the fastest growing new product in automotive and miscellaneous applications the full cold finished product line in T8, T9 and T651 tempers excel in markets where 6262, 6061, 2011 aluminum alloys and 12L14 steels are used today. The automotive applications include ABS manifolds, brake parts, A/C components, transmission valves and transmission sleeves.

AMS5753C
This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, and stock for forging or heading. Primarily for parts, such as turbine blades, bolts, and fittings, requiring high strength up to 1600 degrees F (870 degrees Centigrade) and oxidation resistance up to 1800 degrees F (980 degrees C). This specification has been declared "Noncurrent" by the Aerospace materials Division, SAE, as of October 16, 1987. It is recommended, therefore, that this specification not be specified for new designs.
