Abstract
Abstract There is provided an aluminum base alloy characterized by a substantial amount of silicon and nickel together with smaller amounts of copper and magnesium, and further characterized by the presence therein of beryllium and titanium, said alloy being useful in making molds where hardness and replication of fine detail is required. Latent within the as-cast alloy is developable hardness, fine grain structure, and freedom from microporosity obtained by submitting the alloy cast at from 1,000* to 1,100* F. to a further thermal history.
