Technological properties

Property
Application areas	This product is especially suitable for electrical applications. It is used for bus bar manufacturing that specializes in the transport and the distribution of electricity. PCP Aluminium developed this product to meet complex electrical requirements in order to minimize energy loss. This product is available in a variety of sizes.
Availability	Other thicknesses, widhts and lengths may be available upon inquiry. On request, this product may be milled and coated with protective plastic film on the milled sides.
Dimensional stability	Excellent
Other	AA1370 is the best aluminium you can get for electrical applications: It is made of prime metal without any recycled alloying material. AA1370 is a subset of AA1350 aluminium. 99.7% pure aluminium ensures increased conductivity. PCP aluminium AA1370-50 is annealed (0) since it becomes less prone to deformation with a stress relief heat treatment.
Processing history	Fabricated from prime aluminium cast ingots
Welding	Excellent weldability
