Antimagnetic Disc Springs (Spring Washers)
With antimagnetic materials such as antimagnetic disc springs, precipitation hardening supplies the strength to these non-magnetic and corrosion-resistant disc spring materials.
- CuBe 2 (DIN 2.1247)
- CuBe 2 is precipitation-hardened copper-beryllium alloy that can be used at severely low temperatures. This alloys low modulus of elasticity enables the disc spring material to generate a significantly lower spring force when compared to other various materials. In addition, it has good electrical conductivity.
- NiBe 2 (DIN 2.4132)
- NiBe 2 is suitable for use at elevated temperatures. In addition, the disc springs may be exposed, for brief moments (roughly about 1 hour), to temperatures approximately 100 °C higher than those listed in (Table 5.1)without disturbing their properties.
