Nickel – Silver.

Because of their high strength, corrosion resistance and other excellent mechanical properties the nickel silver strips are suitable for wide range of applications. They are mainly used in electrotechniques, electronics, telecommunication and light techniques, food industry and instrument production. Each hard grade of them are excellently suitable to produce springs. They are used for Coin production and as household items. The Nickel-Silver Strips can be easily and intensively cold-worked, blanked and deep-drawn. These strips are produced on up-to-date continuous casting equipment and high precision rolling mills

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.
