Konel alloyIn 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. The name reflects the cobalt (ko-) and nickel (-kel) in the alloy. An interesting characteristic is that konel grows stronger at high temperatures, whereas other metal becomes weaker with heat. For example, at 600ºC, konel has twice the tensile strength of chrome nickel steel. 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.«
