Aluminum Alloy Types and Characteristics
Aluminum alloy materials can be classified into wrought alloys such as plates, bars, rods, and wire, and cast/die-cast alloys for sand/mold casting. They all have various characteristics and are designated by four digit JIS numbers*. The alloys are assigned 1000 class numbers and the lower two digits denote the associated information. For example, 99.7% aluminum is A1070 and AL-Mg alloy is A5052.

Characteristics
Purpose
Alloy Number*
1000
(Pure aluminum)
Excellent corrosion resistance, machinability, electrical/thermal conductivity. Good surface treatability.
Various containers, electrical appliances, reflector plates
