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.
