Nickel Alloys Monel 400 Springs

Nickel Alloys Monel 400 Springs are high-performance elastic devices manufactured from the resilient Monel 400 nickel-copper alloy (UNS N04400). Zeron Fasteners specializes in producing these high-strength springs, which are designed to absorb energy and release it, maintain force between two surfaces, or dampen motion. The key characteristic of this product is its combination of high tensile strength in spring temper wire and exceptional resistance to various corrosive environments, including seawater, brines, and non-oxidizing acids. The main application of these Monel 400 Springs is in submerged valves, oil and gas down-hole equipment, pump seals, safety relief valves, and instrumentation where consistent mechanical performance and long-term corrosion immunity are absolutely critical.
