回弹后与短轴差值最小

具有优良的导电性能。

Abstract

CuCrZr alloys were prepared by alloy addition method

directly melting and cladding addition method

and spiral springs were produced based on the same heat treatment and subsequent processing.In addition

the properties of the spiral spring produced were tested.The results show that the alloy prepared by the alloying addition has good tensile strength and elasticity modulus

which is about 493 MPa and 180 GPa

respectively

and its compressive resistance exhibits desirable

where the helix angle is 60 degrees

and difference of short axis is the smallest before and after the test

showing the satisfied electrical conductivity performance.
