Abstract
High mechanical strength and electrical conductivity are produced in copper-tin alloys containing 3-16 per cent of tin by cold forging, rolling or drawing with at least a 10 per cent reduction in thickness for an alloy containing 16 per cent of tin and 80 per cent for a 3 per cent tin alloy, and then tempering at 150-350 DEG C. for at least an hour and for a time longer than that required for the production of the desired conductivity. The cold-working and tempering may be repeated. The alloys may also contain one or more of silicon, aluminium, iron, phosphorus, nickel, zinc and magnesium up to a total amount of 2 per cent, the minimum tin content then being reduced to 1 per cent.
