Cupro-Nickel.

The Cupro-Nickel Strips are special products of 3C mainly for Coin production. They can be excellently used for decoration, bijou and jewellery production and for manufacturing of ornamental materials. 3C manufactures these strips by up-to-date horizontal crystallization technology, for the cold reduction modern roll stands are used. These strips have good cold workability that makes possible easy bending and blanking. For soft grades up to 1 mm thickness strips with excellent flatness and trueness to shape can be manufactured using tensile leveling.
