In 1929, the discovery of Konel, a new metal alloy was announced by Erwin Foster Lowry, of the Westinghouse Electric and Mfg. Co. research department of Pittsburgh, Pennsylvania. When used in oxide-coated filaments for radio vacuum tubes (replacing expensive platinum), konel gives much better electron emission. Other uses include turbine blades; also car engine valve stems and pistons. Its composition is 73% Ni; 17.5% Co; 6.5% Fe; 2.5% Ti; 0.2% Mn.

Monday, Sept. 23, 1929

News of a new and valuable alloy was despatched to the Congress by Westinghouse Electric & Manufacturing Co. Erwin Foster Lowry, 38, Michigan-born Ohio State graduate, had compounded nickel, cobalt and ferrotitanium. Result was a metal which grew stronger the hotter it was heated. Other metals become weaker with heat. Mr. Lowry's alloy has a tensile strength of 60,000 lbs. per sq. in. at 600° C. (1112° F.). At the same temperature chrome nickel steel's tensile strength is 30,000 lbs. per sq. in. Name given the new material is konel metal - from ko(balt) plus n(ick)el. Uses are for the filaments of radio vacuum tubes, turbine blades, motor pistons, valves & valve stems.
