Aluminum 0.10 Max Alloy 52 , Soft Glasses Ceramics Sealing High Strength Alloy

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

Applications

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