Abstract

In a process of producing strip or wire, which consists of a monotectic aluminum-silicon alloy comprising a matrix consisting of aluminum and an aluminum-silicon eutectic system and as a minority phase 1 to 50% by weight lead or bismuth included in said matrix, which strip or wire has been continuously cast at a high casting velocity and a high cooling rate from a molten material which has been heated to a temperature above the segregation temperature, and which strip or wire has been subjected to plastic deformation and to a heat treatment, the minority phase which is embedded in the form of elongate platelets in the strip or wire is transformed to more compact shapes by a heat treatment at temperatures of 550.degree. to 600.degree. C.
