...he annealed condition the alloy can be cold worked extensively without an intermediate anneal. Welding Readily welded by all conventional methods. Use AL 1100 consumable electrodes and filler wire. Heat Treatment The alloy does not respond to heat treatment other than to produce the annealed condition, "O" temper, See "Annealing". Hot Working Hot working is readily accomplished if necessary. Cold Working This is an ideal alloy for cold working because of the good ductility in the annealed temper. It can be cold formed by bending, drawing or spinning. Annealing Annealing, which may be necessary after severe cold working, is done at 650 F for sufficient time to allow for thorough heating and then air cooled. Hardening Hardens by cold working only. Electrical Conductivity Electrical conductivity is 53% of copper.

Applications Commonly used in the manufacture of screw machine products, machine parts, atomizer and hose parts, pipe stems, cigarette holders, and tube fittings. Machinability This is a free-machining alloy and both carbide or high-speed tool steel tooling may be used. Carbide tooling is preferred. Rake angles should be 50 degrees for top rake, 32 degree cutting edge, 15 degree side rake and 10 degree clearance. Oils should be used for heavy cutting, Light cutting may be done dry. Foming Bending, shaping and forming in general may be don with conventional tooling. Following cold working the part is usually age hardened to develop better strength properties. Welding Welding of this alloy is NOT recommended. No common methods of producing satisfactory welds have been developed. Forging, or hot working, may be accomplished in the temperature range of 550 to 900 F. Hot Working Hot working may be done at temperatures of 550 to 900 F. Annealing is done at 775 F by holding at that temperature for 2 to 3 hours, followed by controlled cooling at a rate of 50 F per hour down t...
