Nickel CNC Machining

Invar 36 is a nickel-iron alloy with excellent dimensional stability at a large range of temperatures. The ’36’ represents the alloy containing 36% nickel and has a super low coefficient of expansion. Invar 36 is extremely comparable to most qualities of steel/stainless steel in regards to overall appearance.

Kovar is a nickel-cobalt alloy best known for its capacity to increase at a comparable rate to glass when exposed to heat. In addition, the product has superb dimensional stability at a variety of temperature levels.

Inconel 718 is an austenitic nickel-base superalloy that is used in applications needing high stamina. It was originally established for the aerospace market and is still used for the majority of aircraft engine components. It has high toughness, superior weldability with resistance to post-weld fracturing, and excellent creep-rupture strength.

Cost-saving Design Tips

To reduce costs, limit part setups, limit inspection dimensions or tight tolerances, and deep pockets with small radii.


 Nickel CNC machining is the process of using computer-controlled machines to shape, cut, and finish parts made from nickel-based alloys.

Nickel alloys offer high corrosion resistance, excellent strength, and exceptional heat resistance.
