Nickel Alloy Springs

Coiling Technologies fabricates custom nickel alloy springs for the military, oil and gas, automotive, and other industries. The versatile properties and high performance of nickel alloys make them an excellent choice for industrial springs. We strive to manufacture springs that meet or exceed your current product specifications.

Benefits of Nickel Alloy Springs

Nickel alloy springs have outstanding corrosion and high-temperature resistance. Nickel alloys offer high strength, durability, and reliability even amid the harshest environments.

They provide extreme resistance to corrosion under reducing chemical environments and seawater. The properties of nickel alloy make it an in-demand material in the spring manufacturing industry.

Why Use Nickel Alloy?

Nickel is a versatile element and will alloy with most metals. It demonstrates good coiling ability and, in most cases, doesn't require additional lubricants. These factors cause less stress on your equipment, benefiting you with reduced downtime and maintenance.

Many nickel alloys are nonmagnetic. This feature is critical for applications in chronoscopes, gyroscopes, and indicating instruments. However, nickel alloy is highly resistant to electricity and is therefore not suitable as an electrical conductor.

Applications for Springs Fabricated From Nickel Alloys

Springs made from nickel alloy are used in demanding environments such as:

Nickel alloy is typically used to manufacture compression, torsion, and extension springs. However, we can custom-manufacture any type of spring your project requires.

Nickel Alloy Springs FAQs

What are nickel alloy springs, and when does an application require one?

Nickel alloy springs are coiled from nickel base wire or bar rather than carbon or stainless steel, and they exist for two reasons: service temperatures that would relax a steel spring, and corrosive media that would pit or crack one. Coiling Technologies fabricates nickel alloy springs for military, oil and gas, automotive, and other industrial work, in service environments including nuclear installations, aircraft engines, deep oil wells, and valves. If your spring sees hot gas, seawater, brackish water, or reducing acids, and load loss over time is unacceptable, nickel alloy is usually the answer rather than an upgraded stainless grade.

Which nickel alloy grades does Coiling Technologies coil?

CTI coils Hastelloy B-2, Hastelloy C-276, Monel 400, Monel K-500, and Nimonic 90, and also supplies Nitronic and Rene 41 springs. The Inconel grades sit in their own material category on the site, including Inconel 600, 625, 718, and X-750. Compression, torsion, and extension springs are the typical configurations in these alloys, though CTI can custom manufacture any spring type your project requires, including disc springs, wave springs, and wire forms. Grade selection normally comes down to the service environment and to whether you need the strength that only an age hardenable alloy provides.

How do I choose between a solid solution strengthened and an age hardenable nickel alloy?

Solid solution grades such as Inconel 600, Monel 400, Hastelloy B-2, and Hastelloy C-276 get their spring properties from cold work alone, so the only route to higher tensile strength is drawing the wire down harder. Age hardenable grades such as Monel K-500, Inconel 718, and Inconel X-750 carry aluminum and titanium or niobium additions that precipitate during a controlled aging cycle after coiling, which raises yield strength substantially and holds it at temperature. Pick solid solution when corrosion resistance drives the design, and age hardenable when load capacity or relaxation resistance drives it.

Which nickel alloy fits seawater service versus acid service?

Seawater and brackish water point to the nickel copper grades. Monel 400 handles cavitation and erosion well in flowing seawater, and Monel K-500 gives comparable corrosion behavior with roughly triple the yield strength once aged. Reducing acids split by chemistry. Hastelloy B-2 is the specialist for hydrochloric acid and other non-oxidizing acids because of its molybdenum content, while Hastelloy C-276 adds chromium and tungsten and tolerates both oxidizing and reducing conditions. Chloride stress corrosion cracking on the hot side points to Inconel 600, which is immune to that failure mode.

Are nickel alloy springs magnetic, and does that affect design?

Many nickel alloys are nonmagnetic, which matters for chronoscopes, gyroscopes, indicating instruments, and any assembly where a spring sits inside a sensing field. Monel K-500 is nonmagnetic. Magnetic response is not uniform across the family, so if your assembly carries a permeability limit you should state it on the drawing rather than assume the grade name covers it. Nickel alloy is also highly resistant to electrical flow, making it a poor conductor and unsuitable where the spring doubles as a current path. Both properties are design constraints worth confirming before you commit to a grade.

Why source nickel alloy springs from a single facility?

Nickel alloys punish handoffs. Coiling, stress relief or aging, shot peen, and inspection all interact, and when those steps sit at separate vendors the schedule stretches and accountability blurs. CTI performs engineering services, spring design, heat treating, non-destructive testing, powder coating, shot peen, and prototyping in-house in Houston, under one ISO 9001:2015 certified quality management system, without outsourcing to outside vendors. For an age hardenable grade that needs a controlled aging cycle after coiling, that continuity is the difference between a documented process and a chain of separate purchase orders.
