A precipitation hardenable Nickel-Iron-Chromium alloy having outstanding controllable thermoelastic coefficient characteristics and excellent oxidation resistance in high temperature atmospheres. The alloy can be processed to have a constant modulus of elasticity at temperatures ranging from -45 to +65°C (-50 to +150°F).
Diameter: 0.1 - 40mm
Shape: round, square, flat, special shaped
Outstanding controllable thermoelastic coefficient characteristics.
Can be processed to have constant modulus of elasticity from from -45 to +65ºC (-50 to +150ºF).
Good for springs in watches and weighing equipment.
Age hardenable.
