Iron-Nickel-Cobalt

Interested in Nickel Iron Alloys?

Our Iron-Nickel-Cobalt alloy is produced with expansion properties similar to glass and ceramics to enable good glass-to-metal bonding. This alloy retains good formability over a wide temperature range.

HEAT TREATMENT
Because of its effect on the actual structure of the material, there is a distinction made between heat treating the material to facilitate fabrication and heat treating the material to insure optimum conditions for glass sealing, plating or brazing.

STRESS RELIEF ANNEALING
To relieve stress and work hardening of parts at intermediate stages of fabrication. It is intended particularly for drawing, forming and spinning operations.

1. Wash and degrease parts.

2. Anneal in atmosphere controlled furnace. Atmosphere may be wet or dry hydrogen, dissociated ammonia, cracked gas or similar neutral atmosphere.

3. Annealing temperature is not critical; however, high temperatures (greater than 900°C) or extended time periods (longer than 60 minutes) should be avoided because such treatments promote grain growth.

Typical cycle 850°C for 30 minutes.

4. Parts should be held at temperature for the indicated time and then furnace cooled to less than 175°C to avoid oxidation and/or thermal shock (which may cause distortion).
