V, Bi, Ga Effects on Al Extrusion Billets (6063) 1

[seerix]

What are the effects of V,Bi,Ga (small amounts) on aluminum alloy properties and aluminum extrusion?

V: 0.007
Bi: 0.001
Ga: 0.015

Thanks for the help.

Those levels of V, Bi, and Ga will have no effect on the properties of an aluminum alloy extrusion. The standard composition allowance for "other" elements is 0.05% maximum for any individual element or 0.15% maximum the total. Even high purity grades usually only specify Ga as 0.03% max and V as 0.05% max, so as you can see, these particular amounts are considerably lower than standard commercial limits. Here is an example of the Aluminum Association composition limits for wrought alloys:

Thanks again TVP.
