|| Home || Product & Grades || The Brass Strips ||

The brass strips form a wide product range of 3C. They are produced in high quality for universal application to satisfy the strictest requirements of customers. The raw material for the manufacturing is a cast strip, made by modern continuous crystallization process. These strips have good cold-workability that makes possible intensive and easy blanking. Annealed materials can be easily deep-drawn. Fields of application are electronics, lighting technics, metal decoration material industry, vehicle industry, production of household items. Special hard grades are used as spring switch parts. The grades with homogenous structure are used for manufacturing components for refrigerating industry. The strips can be easily polished. After special heat treatment to control the grain size, the materials are suitable for multi-grade cold drawing of high level. Soft qualities can be delivered with pickled surface too. The excellent surface quality is guaranteed by the special technology (multi-step surface processing, bright annealing) developed by 3C. Good flatness and trueness to shape is characteristic for the material. for special request tensile levelling is increasing the trueness to shape under 1 mm thickness.
