Mechanical and electronic components can be subjected to extremely high temperatures, so the materials used to make those components must be able to endure the heat—and perform reliably. Materion's Alloy 360 nickel-beryllium can withstand periodic rises in temperature up to 700°F (350°C), while maintaining good spring characteristics. This makes it ideal for applications such as high-temperature electrical connectors and Belleville washers used in fire sprinkler systems.
Because of the pressure put on this single component, Belleville washers are required to be made of nickel-beryllium alloy which has been proven to withstand challenging conditions. Nickel-beryllium strip Alloy 360 resists corrosion and meets the stress relaxation resistance requirements— retaining 95% of its initial stress after 1,000 hours at 600°F.
Alloy 360 also provides excellent formability and strength that can reach 300,000 psi after a simple one-step heat treatment.
