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. PERFECCIONAMIENTOS EN/O RELATIVOS A UNA ALEACION A BASE DE COBRE. SE FABRICA UNA ALEACION DE COBRE CONSISTENTE ENTRE 0,01 Y 0,05% EN PESO DE TELURIO Y ENTRE 0, 001 Y 0,01% EN PESO DE FOSFORO FORMANDO UNA MASA FUNDIDA EN CALIENTE DE LA ALEACION, COLANDO LA MASA FUNDIDA DE MANERA QUE LA MISMA SE SOLIDIFIQUE RAPIDAMENTE A UNA VELOCIDAD DE MAS DE 1,5 MM. POR SEGUNDO, CON UNA ALTA CADENCIA DE ENFRIAMIENTO DE MAS DE 20GC POR SEGUNDO, A TRAVES DE TODO EL ESPESOR DE LA PIEZA COLADA. ESTA ALEACION RESULTA APROPIADA PARA SER UTILIZADA EN LA PRODUCCION DE UNA TIRA DE RADIADOR PARA UN MOTOR DE COMBUSTION INTERNA.
