Zinc-Aluminum Coated Carbon Wire

Zinc Aluminum coating is known in the industry by trade names Bezinal and Galfan as well as Alumar and Corzal coatings.  It is traditionally a 95% zinc coating with the addition of 5% aluminum.  Other coating concentrations can be for example 90% zinc and 10% aluminum.  This product offers superior resistance to rust over just a hard drawn or regular galvanized product.

This coating can be applied to products such as  high and low carbon wires including  music wire, hard drawn MB and low carbon.
