We're all about pushing the limits of performance, and our Nimonic 90 Alloy Spring Wire for Heavy-Duty Automotive and Racing Components is built to do just that. This superalloy wire isn't just another component; it's a powerhouse designed for the intense heat, vibration, and stress of high-performance automotive and racing environments. If you're searching for automotive spring wire or high-temperature alloy wire that can keep up with the demands of turbocharged engines or Formula 1-level racing, our Nimonic 90 wire delivers the durability and precision you need to stay ahead of the curve.
Let's start with the product itself. Our Nimonic 90 Alloy Spring Wire is crafted from a nickel-based superalloy with a killer composition: 54-62% nickel for a rock-solid base, 18-21% chromium for corrosion and oxidation resistance, 15-21% cobalt for added strength, and 2-3% titanium plus 1-2% aluminum for precipitation hardening. This mix gives the wire its signature ability to handle extreme heat up to 920°C without losing its shape or strength. We manufacture it with precision, starting with vacuum induction melting to ensure purity, followed by hot rolling and cold drawing to achieve custom diameters from 0.05mm to 10mm. Our age-hardening process fine-tunes the microstructure, delivering tensile strength of 1300-1500 MPa at room temperature and creep resistance that holds strong at 125 MPa after 1000 hours at 920°C. Whether you need fine wire for intricate valve springs or thicker coils for suspension systems, we tailor it to your exact specs, ensuring optimal performance in high-stress automotive applications. Add in optional coatings for extra corrosion protection, and you’ve got a wire that thrives in the harshest engine bays and racetracks.
