METHOD OF MAKING BERYLLIUM-ALUMINUM WROUGHT MATERIAL

摘要

A method of producing wrought material containing beryllium and aluminum comprising: forming a casting of said material in a mold having high thermal conductivity material; applying a protective coating to said casting; heating the coated casting at a temperature of 700 DEG to 1,100 DEG F for a period of 5 to 100 hours; extruding the heated casting at a rate of about 13 to 60 inches per minute; removing the jacket from the extruded casting; heating the extrusion at a temperature of 900 DEG to 1,150 DEG F for a period of time of 12 hours to 1 week; and rolling the heated extrusion at a total reduction of 10 to 98%.
