3J01 Elastic Alloy Wire
Professional supplier of 3J01 age-hardening elastic alloy fine wire, diameter 0.08-3mm, with straightening, cutting, and customization services.
Material Overview
3J01 is a nickel-chromium-cobalt-titanium age-hardenable elastic alloy that achieves high elastic limit and excellent elastic properties through γ' phase precipitation strengthening. It offers superior corrosion resistance and non-magnetic characteristics, making it widely used in precision instruments and meter manufacturing.
3J01 alloy wire is produced via vacuum induction melting to ensure material purity and microstructural uniformity. Solution treatment followed by aging yields optimal elastic and comprehensive mechanical properties.

Frequently Asked Questions (FAQ)
What is the heat treatment process for 3J01 alloy wire?
3J01 Alloy Typical Heat Treatment: Solution treatment at 950-980°C followed by air cooling; aging treatment at 500-550°C for 4-6 hours, then air cooled. The solution-treated state facilitates forming; optimal elastic properties are achieved after aging.
What's the difference between 3J01 and 3J53?
3J1 is a high-elasticity alloy with a high elastic limit, ideal for diaphragms and bellows requiring large deformation. 3J3 is an constant-elasticity alloy with an extremely low temperature coefficient of elastic modulus, suited for resonators and delay lines where high frequency stability is critical.
Can 3J01 alloy wire be welded?
3J01 alloy can be welded using TIG, resistance welding, and other processes. However, welding disrupts the age-hardening effect, so post-weld aging treatment is required to restore elastic properties. Welding in the solution-treated condition is recommended.
What is the minimum wire diameter for 3J01 alloy wire?
3J01 alloy wire offers a minimum diameter of 0.08mm, meeting the manufacturing requirements for precision elastic components. Wire diameter tolerance is controlled within ±0.005mm.
