Method of liquid forming a copperberyllium alloy

Claim 1

THE METHOD OF PRODUCING A BERYLLIUM-COBALT-COPPER ALLOY BODY CONSISTING OF BERYLLIUM FROM ABOUT 1.65% TO ABOUT 1.75%; COBALT FROM ABOUT 0.20% TO ABOUT 0.40% AND REMAINDER COPPER OF NOT LESS THAN 99.295% PURITY; CHARACTERIZED BY A FINE EQUIATED CRYSTAL GRAIN STRUCTURE OF SUBSTANTIALLY ALL ALPHA PHASE; AN ULTIMATE TENSILE STRENGTH OF 204,600 P.S.I.; A YIELD STRENGTH AT 0.01% OFFSET OF 119,600 P.S.I.; AN ELONGATION OF 11.5% IN 2" AND A ROCKWELL "C" HARDNESS OF 33.8; WHICH METHOD CONSISTS OF POURING THE MELT, WITH A TIME LAPSE OF NOT MORE THAN 18 SECONDS, AT A TEMPERATURE NOT EXCEEDING 1875*F., INTO A DIE HEATED TO AT LEAST 500*F. AND WITH AN UPPER LIMIT OF 840*F., CLOSING THE DIE WITH A PLUG HEATED TO AT LEAST 500*F. AND WITH AN UPPER LIMIT OF 810*F., IMPOSING A PRESSURE ON THE METAL IN THE DIE OF AT LEAST 1400 P.S.I. FOR NOT LESS THAN 3 MINUTES, THEN FORMING THE BODY FROM THE INGOT BY EXTRUSION, SOLUTION ANNEALING THE BODY AT ABOUT 1475*F. FOR AT LEST 3 HOURS, WATER QUENCHING AND THEN AGEING THE ANNEALED BODY AT ABOUT 650*F. TO ABOUT 675* F. FOR APPROXIMATELY 3 HOURS.
