Nickel Alloy Spring Wire


Nickel Alloy Spring Wire


Fushun produces a full line of nickel alloy spring wire, produced for the performance required in aerospace, automotive, oil & gas, and general industrial applications. Wire is available in a range of alloys and packaging options.


Why choose our nickel alloy spring wire?

Our wire exhibits excellent coiling ability at high speeds and often requires no additional lubricant. This results in less stress on coiling equipment, preserving equipment life, minimizing downtime and maximizing throughput and profits. If additional lubrication is required, we offer several performance coating options.


Our technical and metallurgical team talk through spring manufacturers’ technical requirements, material application and help solve potential manufacturing situations around the need for corrosion resistant and high temperature performing wire.


We understand exactly what the spring maker needs for precision coiling and supply exactly how they want it, guaranteeing consistency in temper and a dead cast whether that is wire in coils with a soap coating or clean on spools. There is even the option of straight bars.


What is nickel alloy spring wire?

Nickel-based alloys are especially useful spring materials. Their chemical composition makes them highly corrosion resistant, and they perform well in extreme high and low temperatures. Most nickel alloys are nonmagnetic, an important property for devices such as gyroscopes, chronoscopes, and indicating instruments. Nickel alloys exhibit high electrical resistance, and therefore should not be used as electrical conductors.


Nickel alloys for use in harsher environments include MP35N, Inconel® 718, Inconel® 600, and Alloy X750. Tensile Strengths range from gull soft to full hard “spring temper”. Performance is tested on every lot of material to ensure we meet your requirements, and full reports are available upon request.


Where nickel alloy spring wire use?

As specialists in High Performance nickel alloys, one of our largest and most diverse markets globally is the spring manufacturing industry. They produce compression springs, tension springs, torsion springs and formed parts from our wire to perform in critically demanding places like aircraft engines, nuclear installations, valves and deep down oil wells – where other wire fails to perform.


Size of nickel alloy spring wire

What we do really well is producing any wire size between 0.025mm (.001”) to 21mm (.827”) to precise tolerances – typically delivered within 3 weeks. The spring industry today is demanding more wire that is certified to an increasing number of specifications, or produced to the customer’s own special mechanical properties, which we also support very well. Other sizes and alloys are available upon request.
