Description

Materion Performance Alloys’ nickel beryllium strip Alloy 360 (UNS number N03360) combines unique mechanical and physical properties.


Properties of nickel beryllium Alloy 360 strip that a designer can use include ultimate tensile strength approaching 300,000 psi (2000 MPa), yield strength up to 245,000 psi (1690 MPa), excellent formability, stress relaxation less than 5% at 400º F (200°C), and fatigue strength (in reverse bending) of 85,000-90,000 psi (586-655 MPa) at 10 million cycles. It has corrosion resistance surpassing stainless steel. Typically, this alloy is used for mechanical and electrical / electronic components that are subjected to elevated temperatures (up to 700º F / 370°C for short times), and require good spring characteristics at these temperatures.
