Balls of this category represent those made with special materials or special finish and are mostly used in tool & related industries. We are in a position to supply non-ferrous balls in aluminum, brass, bronze, copper, nickel, etc. Each material has different characteristics and is suitable for a special application. Broad range of non-ferrous balls manufactured by us include Copper Alloy balls, Nickel-Copper Alloy balls and Aluminum Alloy balls.
