Brass alloy as raw materials for semi solid metal casting

Abstract

A brass alloy as raw materials for Semi Solid Metal casting has a component composition containing Zn of 8 to 40 mass %, Zr of 0.0005 to 0.04 mass %, P of 0.01 to 0.25 mass %, and a balance of Cu and inevitable impurities, further containing one or more kinds of Si of 2 to 5 mass %, Sn of 0.05 to 6 mass %, and Al of 0.05 to 3.5 mass % as needed, and further containing one or more kinds of Pb of 0.005 to 0.45 mass %, Bi of 0.005 to 0.45 mass %, Se of 0.03 to 0.45 mass %, and Te of 0.01 to 0.45 mass %.
