Key Properties and Characteristics:
Controllable Thermoelastic Coefficient:
Alloy 902's thermoelastic coefficient can be tailored through cold working and heat treatment, allowing for optimization for specific applications.
Stable Elastic Modulus:
It can be processed to exhibit a constant modulus of elasticity over a temperature range, typically -45 to +65°C (-50 to +150°F).
Low Magnetostriction:
The alloy has low magnetostrictive properties, making it suitable for certain magnetic applications.
Age Hardenable:
Alloy 902 can be strengthened through heat treatment after the alloy is formed.
Corrosion Resistance:
It offers good corrosion resistance in industrial and seawater environments, with corrosion rates typically below 0.001 inch per year.
Applications in Industry:
Precision Instruments:
The alloy's temperature-stable modulus makes it ideal for springs in watches, weighing machines, and other precise instruments.
Resonant Devices:
It's used in resonant vibrating equipment like electro-mechanical filters, tuning forks, and vibrating reeds, where constant frequency is essential.
Springs:
Both helical and leaf springs in precision applications benefit from the alloy's properties.
