Technical characteristics

Alloy CW708R (CuZn31Si) is a wrought brass according to DIN 17670 DIN 17672… This grade of brass is not hardened by heat treatment and acquires the desired properties only as a result of strain hardening — forging, cold drawing or rolling. The shade varies from alloy steel (high zinc content) to light yellow (high copper content).

Application

Thanks to the nice color of brass is used in decorative detail, but also in the manufacture of electrical components, which has a value of good electrical conductivity and mechanical strength of the material. Corrosion resistance allows the use of brass for the manufacture of sanitary fittings and slide bearings with low working speeds. The presence of silicon increases the level of mechanical properties.
