Abstract
A Cu—Zn—Si alloy includes, in % by weight, 70 to 80% of copper, 1 to 5% of silicon, 0.0001 to 0.5% of boron, up to 0.2% of phosphorus and/or up to 0.2% of arsenic, a remainder of zinc, plus inevitable impurities. Products using the alloy and processes for producing the alloy are also provided. The alloy is distinguished by an improved resistance to oxidation and by uniform mechanical properties.
