PURPOSE:To make the resulting titled alloy inexpensive and easy to cut and to enable the melting and heat treatment in the air by providing a specified composition consisting of Mn, Zn and Cu. CONSTITUTION:This shape memory Cu alloy consists of, by weight, <=12% Mn, 26-44% Zn and 62-65% Cu. Al may be added to the alloy so as to provide a composition consisting of <=12% Mn, <=3% (X%) Al, (26-4X)-44% Zn and (62+3X)-(56-X)% Cu. The working (transformation) temp. of the ternary alloy is usually about -150 deg.C- room temp. The working temp. can be raised up to a temp. above room temp. by adding Al. |
