Working with Nickel Beryllium 360-TH04
Is Nickel Beryllium 360 easy to machine?
Machine in the annealed temper where possible; in the aged HRC 50+ condition use carbide/CBN, rigid setups, low speeds and full wet extraction — beryllium-bearing dust and mist are a health hazard.
Can Nickel Beryllium 360 be welded?
Fusion welding is difficult (BeO film, hot-cracking) — prefer resistance/spot or electron-beam welding under local exhaust, and re-age after joining.
Can Nickel Beryllium 360 be formed, bent or molded?
Form, coil or draw in the A (annealed) temper and then age-harden; HT material is essentially unformable and can only take small radii.
What surface finishes work on Nickel Beryllium 360?
Not anodizable; degrease and passivate, or apply electroless nickel/gold plating for contacts; the aged alloy polishes to a bright, hard, non-sparking surface.

Nickel Beryllium 360-TH04 — frequently asked
What is Nickel Beryllium 360-TH04 used for?
Nickel Beryllium 360-TH04 is typically used for oilfield connector springs, precision instrument parts, non-sparking tools and surgical instruments. In short: highest-strength nickel spring alloy; non-magnetic, non-sparking; beryllium dust controls required.
What is the yield strength of Nickel Beryllium 360-TH04?
Nickel Beryllium 360-TH04 has a typical yield strength of 1,650 MPa (239 ksi) and a tensile strength of 1,900 MPa (276 ksi) — stronger than 100% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is Nickel Beryllium 360-TH04 easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Machine in the annealed temper where possible; in the aged HRC 50+ condition use carbide/CBN, rigid setups, low speeds and full wet extraction — beryllium-bearing dust and mist are a health hazard.
Can Nickel Beryllium 360-TH04 be welded?
Not readily — weldability is rated poor (30/100). Fusion welding is difficult (BeO film, hot-cracking) — prefer resistance/spot or electron-beam welding under local exhaust, and re-age after joining.
What surface finishes work on Nickel Beryllium 360-TH04?
Not anodizable; degrease and passivate, or apply electroless nickel/gold plating for contacts; the aged alloy polishes to a bright, hard, non-sparking surface.
Can Nickel Beryllium 360-TH04 be formed, bent or molded?
Form, coil or draw in the A (annealed) temper and then age-harden; HT material is essentially unformable and can only take small radii.
What is the maximum service temperature of Nickel Beryllium 360-TH04?
Nickel Beryllium 360-TH04 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Nickel Beryllium 360-AT and Nickel Beryllium 360-A?
AT is the default condition — the standard high-strength condition: form in A temper, then age (~500 °C) for HRC ~50 with good ductility retained. A: softest supply condition — pick it when parts must be deep drawn, coiled or heavily formed before age hardening. Yield strength is 1,240 MPa in AT versus 340 MPa in A.
