Thermally Stable Invar 36 Nickel Alloy Rods
- Yield Strength: 40,000 psi
- Hardness: Rockwell B90 (Medium)
- Temper Rating: Softened (Annealed)
- Specifications Met: ASTM F1684
Because Invar 36 holds its size and shape when temperatures rise, this nickel-iron alloy is the go-to material when dimensional stability is required. It is commonly used when precision is a priority, such as for scientific instruments and optical devices.

Easy-to-Machine Thermally
Stable Kovar Nickel Alloy Sheets
- Yield Strength: 50,000 psi
- Hardness: Rockwell B80 (Medium)
- Temper Rating: Softened (Annealed)
- Specifications Met: ASTM F15
This nickel-iron-cobalt alloy expands at the same rate as glass when heated. It offers better machinability than Invar 36 and is often used anywhere a dependable glass-to metal seal is required, such as in diodes and microwave tubes.
