What is Alloy 1350?
1350 is widely used in applications where good electrical conductivity is required. It has an aluminum purity of 99.5% or purer with tight controls on certain impurities that could adversely affect conductivity.
Compositions are listed as weight percent. Limits are given as a maximum unless indicated as a range.
