Product Description

Alloy 52 Controlled Expansion Alloy for Soft Glasses and Ceramics Sealing



Alloy 52 was developed for glass-to-metal seals for some of the soft glasses and ceramics. The alloy’s rate of thermal expansion is virtually constant to a temperature of about 1050°F (565°C).


Key features

  •  Near zero coefficient of linear thermal expansion
  •  High strength and toughness at cryogenic temperatures



  •  Magnetic reed switches
  •  Glass to metal seals that need controlled linear expansion

Typical chemical composition 

  •  Carbon: 0.05 max
  •  Silicon: 0.30 max
  •  Manganese: 0.60 max
  •  Nickel: 50.5 nom
  •  Chromium: 0.25 max
  •  Iron: Balance
  •  Phosphorus: 0.025 max
  •  Sulfur: 0.025 max
  •  Aluminum: 0.10 max
