Hello rahm,

The ASTM International Specification ASTM B566 - 04a Standard Specification for Copper-Clad Aluminum Wire covers the four classes of copper-clad aluminum wire as follows:
Class 10A—Nominal 10 volume % copper, annealed.
Class 15A—Nominal 15 volume % copper, annealed.
Class 10H—Nominal 10 volume % copper, hard-drawn.
Class 15H—Nominal 15 volume % copper, hard-drawn.

It can be purchased at:

You may be able to obtain a license for the manufacturing technology from Fushi Copperweld Inc. (Chinese) at

You may also wish to talk with the folks at BWE Ltd. (UK), the makers of the Conform/ Conklad metal extrusion systems.
