Let's start with the product itself. Our Nimonic 90 Nickel-Chromium-Cobalt Spring Wire is crafted from a superalloy renowned for its ability to handle extreme conditions. The composition centers on nickel as the primary element, making up about 54-62%, which provides a stable matrix for high-temperature stability. Chromium at 18-21% enhances corrosion and oxidation resistance, while cobalt at 15-21% boosts overall strength and creep resistance. Additions of titanium (2-3%) and aluminum (1-2%) allow for precipitation hardening, a key process that hardens the alloy during heat treatment, giving it that superior creep resistance essential for high-temperature service. We manufacture this wire through a meticulous process: starting with vacuum induction melting to ensure purity, followed by hot forging, cold drawing to precise diameters, and finally age-hardening to lock in mechanical properties. The result is a spring wire available in diameters from 0.05mm to 12mm, with customizable tempers that suit everything from soft annealing for easy coiling to full hard for maximum resilience. What sets our Nimonic 90 spring wire apart is the focus on uniformity—every batch undergoes rigorous testing for tensile strength, yield, and elongation, ensuring it performs consistently in high-temperature environments. For industries needing high-temperature spring wire that doesn't falter under prolonged heat exposure, this product delivers with low thermal expansion and excellent fatigue life, making it a go-to for demanding applications.
