L605 Cobalt Alloy Wire Haynes25 / UNS R30605
Professional supplier of L605 high-temperature alloy fine wire, diameter 0.08-3mm, with straightening, cutting, and customization services available.
Material Overview
L605 (Haynes25 / UNS R30605) is a cobalt-based superalloy wire featuring excellent high-temperature strength, oxidation resistance, and wear resistance. It maintains superior mechanical properties at temperatures up to 1100°C and is widely used in extreme environments such as seal bristles for jet engines and fasteners for high-temperature equipment.
L605 alloy wire is produced via a dual-process method combining vacuum induction melting and electroslag remelting, ensuring high material purity and uniform microstructure. The wire features a smooth surface finish with dimensional accuracy up to ±0.01mm, meeting stringent requirements for precision elastic components and high-temperature seals.

Frequently Asked Questions (FAQ)
What is the maximum operating temperature in degrees Celsius for L605 alloy wire?
L605 alloy wire maintains excellent mechanical properties at high temperatures up to 1100°C, with a short-term maximum service temperature of 1200°C. For long-term use, keep the temperature below 1000°C for optimal performance.
What is the difference between L605 wire and GH5188 wire?
L605 is a cobalt-based alloy, while GH5188 is a nickel-based alloy. L605 offers superior wear resistance, making it ideal for friction applications such as sealing brush bristles; GH5188 provides better oxidation resistance, suitable for pure high-temperature environments like combustion chambers. Choose between them based on specific operating conditions.
What is the minimum wire diameter available for L605 alloy?
L605 alloy wire features a minimum diameter of 0.08mm, meeting the manufacturing needs of precision elastic components and micro-springs. Wire diameter tolerance is controlled within ±0.005mm.
Can L605 wire be welded? What process should be used?
L605 wire can be joined using TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), or resistance welding. ERNiCrMo-3 or ERNiCrMo-4 filler wire is recommended; preheat to 200-300°C before welding.
