Property Results

Chemistry Data :

Principal Design Features		This alloy is commercially pure aluminum with excellent forming characteristics.

Applications		Commonly used in spun hollowware, fin stock, heat exchanger fins, dials and name plates, cooking utensils, decorative parts, giftware, rivets and reflectors, and in sheet metal work.

Machinability		This alloy has very good machinability. Best results are obtained when machining is done with the alloy in hard temper. Carbide tooling is preferred, but high speed steel tooling may also be used. For heavy cuts an oil lubricant should be used otherwise turning may be done dry.

Forming		Forming, either hot or cold, is readily accomplished with this alloy. In the 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”.

Forging		The alloy may be hot forged with no difficulty.

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.

Aging		Not applicable to this alloy.

Tempering		Not applicable to this alloy.

Hardening		Hardens by cold working only.

Other Physical Props		Electrical conductivity is 53% of copper.

Other Mechanical Props		Shear strength values are: “O” (annealed) temper 9 ksi, H12 temper 10 ksi, H18 temper 13 ksi
