NICKEL BERYLLIUM ALLOY 360 FOR HIGH TEMPERATURE ENVIRONMENTS


Mechanical and electronic components can be subjected to extremely high temperatures, so the materials used to make those components must be able to withstand the heat—and perform reliably. Materion’s nickel beryllium Alloy 360 can withstand periodic rises in temperature, up to 700°F (350°C), while maintaining good spring characteristics. This makes it ideal for high temperature environments like thermostats, bellows, diaphragms, burn-in and test sockets (BiTS) and even Belleville washers used in fire protection sprinkler heads. 

Read our product brief to learn more about why Alloy 360 is used in corrosion resistant Belleville washers. 

ADVANTAGES OF ALLOY 360

Our Alloy 360 offers high resistance to wear, corrosion, thermal shock and oxidation from room temperature up to 800°F (425°C). Other advantages include:

  • High strength and hardness
  • High conductivity 
  • Yield strength up to 245 ksi
  • Excellent formability with stress relaxation less than 5% at 400° F
  • Fatigue strength (in reverse bending) of 90 ksi at 10 million cycles
