A beryllium-nickel alloy for mechanical and electrical/electronic components that require good spring characteristics at elevated temperatures has reportedly been developed by Brush Engineered Materials, Cleveland, Ohio. Alloy 360 (UNS N03360) is said to provide ultimate tensile strength of 2100 MPa (300 ksi) and yield strength up to 1700 MPa (245 ksi). It also has excellent formability and less than 5% stress relaxation at 200[degrees]C (400[degrees]F).
Fatigue strength in reverse bending is reported to be 590 to 620 MPa (85 to 90 ksi) at 10 million cycles.
Tests at stress levels of 50% and 100% of the 0.2% offset yield strength and ...
