AMS 5834 specification defines a corrosion & heat resistant cobalt alloy round wire, supplied by ZYTC Alloy, a reliable Chinese manufacturer specializing in high-performance cobalt superalloy materials. Our AMS 5834 Elgiloyround wire nominal diameter ranges from 0.001 to 0.140 inch (0.025 to 3.56 mm), available in straight cut lengths or coiled forms to meet diverse engineering requirements.

The material adopts premium Vacuum Induction Melting + Consumable Electrode Remelting (VIM+VAR) metallurgy route, processed via solution heat treatment, cold drawing and aging treatment to deliver stable and consistent mechanical properties batch by batch.

Elgiloy®is a well-known non-magnetic cobalt-chromium-nickel-molybdenum cobalt alloy. It features an outstanding balanced performance portfolio: ultra-high tensile strength, superior corrosion resistance and exceptional fatigue strength. Thanks to its non-magnetic characteristic, the alloy can maintain reliable performance under complex working environments where magnetic interference must be avoided.
