Brass with increased resistance to dezincification and machinability

摘要

The present invention concerns an essentially arsenic-free brass alloy with improved (i) dezincification resistance, (ii) machinability, and (iii) protection against intergranular grain boundary corrosion, wherein said brass alloy comprises 62-68% by weight of Cu, 0.02-1.00% by weight of Pb, 0.2-0.6% by weight of P, 0.02-0.06% by weight of Sb, and balance Zn, and the brass alloy being characterized in that it comprises 5% of β-phase, preferably 1%. In addition, the invention concerns a method for the production of said brass alloy.
