Good mechanical property :Own excellent tensile strength, flexibility and extensibility Low weight: the density is only about *5% of pure copper so under the same volume, the cost will be greatly reduced. Advanced machining processing technique: Solid-Liquid machining processing technique to bond copper and aluminum permanently and firmly. Also, the combination strength continues to reinforce when use. Good extensity and productivity: under special heat treatment, the product owns good plasticity, which is well used in the process of bend, drill and shear. Best choice: Save copper material, low production cost and environment friendly.
