![]() ![]() It also has high chemical resistance at a variety of temperature ranges. AMS 5387 / Cobalt Alloy 6 – This type of alloy is the most frequently employed because it works well in general wear scenarios.KA3 cobalt alloy - It is resistant to abrasion and erosion due to its high carbon content.AMS 5385 / Cobalt Alloy 21 - AMS 5385 possesses reduced ductility and has exceptional thermal and mechanical shock resistance.It is extremely durable in metal-on-metal applications and can operate effectively at high temperatures. AMS 5382 / Cobalt Alloy 31 - This type is often characterized as having high tensile quality.The following are the most popular air-melted cobalt alloys: ![]() There are many cobalt alloys, each with special qualities and advantages. Moreover, this type of alloy displays good edge and thermal fatigue resistance in high-temperature settings like turbocharger turbines and jet aircraft turbines. Due to their strength and lubricity, cobalt alloys are used in high friction bearing settings or products with an anti-galling quality. Orthopedic implants that do not degrade over time are made using cobalt-based investment castings. However, reductive smelting can be used to create pure cobalt. ![]() Similar to nickel, only chemically mixed forms of cobalt (natural alloys) can be found in nature. Due to its superior magnetic properties, cobalt is used in large quantity for the production of high-performance magnetic materials.Cobalt Alloys: What You Need to Know What is Cobalt?Ī passivating oxide naturally covers and guards the strong, glossy, silver-gray metal cobalt against oxidation, which causes rust. In vibration, conventional magnetic steel loses nearly one-third of magnetism, while cobalt steel only loses 2%-3.5% of magnetism. The coercive force of magnetic steel containing 60% of cobalt is 2.5 times higher than that of conventional magnetic steel. The curie point of iron is 769℃ and nickel is 358℃ that of cobalt can reach 1150℃. Under the effect of heat, the temperature of magnetic loss is called the curie point. Due to its good high temperature resistance, corrosion resistance and magnetic performance, cobalt is widely used in aerospace, machinery manufacturing, electrical and electronic, chemical, ceramic and other industrial areas, and is one of the important raw materials for the production of high temperature alloys, hard alloys, ceramic pigments, catalysts and batteries.Ĭobalt is one of the few metals that can keep its magnetism with only one magnetization. It is widely used in biochemistry for activation analysis in electroplating, corrosion and catalysis for tracer research in medical treatment for radiological examination and treatment. There are few land reserves, seabed manganese tuberculosis is an important long-term resource of cobalt.Ĭurrently, the traditional areas of consumption and application of cobalt are mainly battery materials, super heat-resistant alloys, tool steels, hard alloys, magnetic materials cobalt in the form of compounds is mainly used as catalysts, desiccants, reagents, pigments and dyes.Ĭobalt-60 is a widely used radioactive material. Cobalt resources are mostly associated with copper-cobalt ore, nickel-cobalt ore, arsenic-cobalt ore and pyrite deposits. It is one of the important strategic resources. Cobalt is ductile and ferromagnetic, and has a metal luster of silver gray.Ĭobalt is a very scarce small metal resource and is known as “industrial monosodium glutamate” and “industrial tooth”. Cobalt, chemical symbol Co, atomic number 27, melting point 1495℃, is a high melting point metal.
