Working with NiCr60/15 1/2H

Is NiCr60/15 easy to machine?

Work-hardens rapidly — use rigid setups, sharp positive-rake carbide, heavy positive feed, low speed (~20–30 m/min) and flood coolant; avoid dwelling.

Can NiCr60/15 be welded?

Readily spot/resistance welded and TIG welded to itself with matching NiCr filler; keep heat input low, clean off oxide first, and avoid sulphur-bearing greases before welding.

Can NiCr60/15 be formed, bent or molded?

Excellent drawability and coilability in the annealed state; heavily cold-worked wire should be stress-relieved or given a first controlled burn-in to avoid coil distortion.

What surface finishes work on NiCr60/15?

Not anodisable; normal practice is a pre-oxidation cycle in air (~1000 °C) to form the protective chromia film — avoid plating or oils that leave sulphur/halide residues.

NiCr60/15 1/2H — frequently asked

What is NiCr60/15 1/2H used for?

NiCr60/15 1/2H is typically used for appliance heating elements, immersion heaters and industrial resistors. In short: lower-cost nichrome grade; medium-duty heating elements; good drawability and coilability.

What is the yield strength of NiCr60/15 1/2H?

NiCr60/15 1/2H has a typical yield strength of 620 MPa (89.9 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 81% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.

Is NiCr60/15 1/2H easy to machine?

Not especially — machinability is rated poor (27/100, better than 80% of nickel alloy grades). Work-hardens rapidly — use rigid setups, sharp positive-rake carbide, heavy positive feed, low speed (~20–30 m/min) and flood coolant; avoid dwelling.

Can NiCr60/15 1/2H be welded?

Yes — weldability is rated good (60/100). Readily spot/resistance welded and TIG welded to itself with matching NiCr filler; keep heat input low, clean off oxide first, and avoid sulphur-bearing greases before welding.

What surface finishes work on NiCr60/15 1/2H?

Not anodisable; normal practice is a pre-oxidation cycle in air (~1000 °C) to form the protective chromia film — avoid plating or oils that leave sulphur/halide residues.

Can NiCr60/15 1/2H be formed, bent or molded?

Excellent drawability and coilability in the annealed state; heavily cold-worked wire should be stress-relieved or given a first controlled burn-in to avoid coil distortion.

What is the maximum service temperature of NiCr60/15 1/2H?

NiCr60/15 1/2H is rated for continuous use to about 1,150°C (2,102 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between NiCr60/15-ANN and NiCr60/15-CD?

ANN is the default condition — standard stocked condition for coiling heating elements: maximum ductility, stable resistance. CD: full-hard as-drawn wire for tight-tolerance winding, cutting wire and springy elements; anneals out on first firing. Yield strength is 390 MPa in ANN versus 850 MPa in CD.
