For the measurement of tension relaxation different test procedures are used, based on the ASTM E-32-86.
Fig. 5.44 <xr id="fig:Relaxation behavior of selected copper based materials"/> Fig. 5.44 illustrates the different relaxation behavior of some copper alloys. Good behavior is shown for CuNi3Si1Mg and CuCrSiTi while CuZn30 and CuSn6 exhibit a less favorable relaxation tendency.
