Products of Cobalt Alloy Materials

PHYNOX-ELGILOY-2.4711-UNS R30003

PHYNOX (also known as Elgiloy) is a high-performance cobalt-based spring alloy with an excellent elastic limit, outstanding fatigue resistance, and exceptional corrosion resistance. The material maintains stable elastic properties in the cold-worked condition and demonstrates extremely high reliability under high-stress cyclic loading environments. With good biocompatibility and long-term stability, it is widely used for high-precision medical components and demanding industrial spring applications.

AISI631-1.4568-17-7PH-UNS S17700-X7CrNiAl17-7-SUS631

L605-2.4964-UNS R30605

L605 is a typical cobalt-based superalloy based on the Co-Cr-W-Ni system. It offers excellent high-temperature strength, oxidation resistance, and outstanding wear resistance, while maintaining good stability and fatigue resistance in elevated-temperature environments. The alloy also provides good formability and weldability, making it widely used in demanding operating conditions that require high temperature resistance, high stress performance, and excellent corrosion resistance.

CoCr28Mo Low Carbon Alloy (CCM Alloy 1 / UNS R31537 / 2.4979)

CCM (CoCr28Mo Alloy 1) is a typical low-carbon medical-grade cobalt-chromium-molybdenum alloy, generally corresponding to high-purity Co-Cr-Mo system materials used for casting or wrought applications. This alloy offers excellent wear resistance, outstanding corrosion resistance, and good biocompatibility, allowing it to maintain stable performance in long-term in vivo environments or high-load operating conditions. Its high strength and fatigue resistance make it especially suitable for load-bearing and high-wear critical components.

CCM-CoCr28Mo-alloy2-2.4979-UNS R31538

CCM (CoCr28Mo Alloy 2) is a high-carbon cobalt-chromium-molybdenum alloy. Compared with low-carbon grades, it offers superior wear resistance and higher hardness, making it suitable for high-friction and high-load operating conditions. The material also provides good corrosion resistance and biocompatibility, demonstrating excellent stability in long-term service environments. It is especially suitable for critical components requiring exceptionally high wear resistance.

MP35N-2.4999-UNS R30035

MP35N is a cobalt-nickel-chromium-molybdenum multiphase alloy that combines ultra-high strength, excellent corrosion resistance, and good fatigue resistance. After cold working and age hardening, its strength can be significantly improved, while maintaining stable performance in marine, high-temperature, and highly corrosive environments. In addition, this material offers good biocompatibility and non-magnetic or low-magnetic characteristics, making it widely used in critical applications requiring high reliability and high safety performance.
