Abstract
A precipitation hardenable alloy suitable for forming molds for continuous casting of steel and other metal containing, by weight, 0.2-2.0% nickel, 0.05-0.5% beryllium, 0.01-1.0% niobium and the balance essentially copper. The alloy is subjected to heat treatment including solution treatment and aging, so that it has improved strength, high thermal conductivity and high toughness at elevated temperatures. The alloy may contain 0.03-0.6 wt % zirconium, 0.03-0.6 wt % zirconium and 0.01-0.1 wt % magnesium, or 0.03-0.6 wt % zirconium and 0.01-0.2 wt % titanium in place of the 0.01-1.0 wt % niobium.
