Abstract (en)
Disclosed is a brass having reduced amounts of lead and nickel or not containing them, and having improved castability and corrosion resistance. The brass, comprising Sn in the range of 0.05% to 0.2% by mass, at least one or more elements selected from the group consisting of Sb, As, and P with total amount thereof in the range of 0.05% to 0.32% by mass, Al in the range of 0.1 % to 0.5% by mass, Zn in the range of 33.0% to 40.0% by mass, at least one or more elements selected from the group consisting of Pb and Bi with total amount thereof in the range of 0.005% to 0.25% by mass, Ni in the range of 0.5% or less by mass, Si in the range of 0.5% or less by mass, at least one or more elements selected from the group consisting of Fe and B with total amount thereof in the range of 0.0001% to 0.3% by mass, and the balance substantially consisting of Cu and unavoidable impurities, and also an apparent content of Zn in the range of 36% to 41 %, is excellent in castability and corrosion resistance.
