OSTI ID:4067023
A method of extruding or drawing beryllium through a die wherein a layer of silver or gold is provided between the die and the beryllium to prevent contact is described. An adherent coating of silver or gold is deposited on the beryllium by electrolytic action. For warm drawing beryllium the die speed is 0.2 to 40 inches per minute and the temperature of the metal is 400 to 500 deg C. For extruding the die speed is 1 to 5 feet per second at 500 to 700 deg C. (N.W.R.)
