IMPROVEMENTS IN OR RELATING TO MAKING A COPPER-BASED ALLOY

A copper alloy containing between 0.001 and 0.05% by weight of tellurium and between 0.001 and 0.01% by weight of phosphorus is manufactured by forming a molten mass of the alloy and casting the molten mass in such a way that it solidifies rapidly at a speed greater than 1.5 mm per second, with a hi...

Zusammenfassung:	A copper alloy containing between 0.001 and 0.05% by weight of tellurium and between 0.001 and 0.01% by weight of phosphorus is manufactured by forming a molten mass of the alloy and casting the molten mass in such a way that it solidifies rapidly at a speed greater than 1.5 mm per second, with a high cooling rate, greater than 20 DEG C per second through the entire thickness of the cast mass.
