Abstract

A brass alloy, a process for the production of a brass material or semi-finished brass product from that type of a brass alloy, as well as to the utilization of the brass material; in essence, the brass alloy for semi-finished products and semi-finished articles, which in addition to a good workability must possess a high resistance to wear, especially when employed for synchronous rings. The foregoing is possible through the intermediary of entirely determined contents of chromium and/or zircon in the previously described brass alloy. The chromium contents hereby vary, on the one hand, in dependence upon the silicon contents, and on the other hand, however, also to a lesser measure upon the remaining alloy components within the range of between 0.01 to 0.15% by weight, and preferably between 0.05 and 0.1% by weight.
