Cobalt Alloys
Applications that push beyond the limits of conventional stainless alloys and nickel alloys require a material built to withstand punishing heat, aggressive corrosion, and constant wear.
As a trusted cobalt alloy supplier, Stainless Steel Products provides cobalt base alloys in round wire, flat wire, coil and strip, and straight-cut forms, customized to your exact specifications for alloy type, diameter, temper, and tolerances.
Cobalt alloys combine cobalt with chromium, tungsten, molybdenum, and nickel to deliver an exceptional balance of high-temperature strength, wear resistance, and corrosion protection. These properties make them indispensable across industries where component failure is not an option. Stainless Steel Products supplies proven grades, including Stellite, L605, MP35N, and Elgiloy, in the product forms and packaging your production line requires.
Why Engineers Specify Cobalt Alloys
Cobalt superalloys retain their strength at temperatures exceeding 1000°F (538°C), well beyond the capabilities of standard stainless steels. This thermal stability makes them the preferred choice for turbine blades, combustion chambers, and exhaust components in aviation and defense applications. In the medical device field, grades like MP35N and Elgiloy offer biocompatibility and non-magnetic properties essential for orthopedic implants, cardiovascular stents, and surgical instruments. Oil and gas teams select cobalt alloys for downhole tools and valve components that must survive sour gas wells, high-pressure environments, and prolonged exposure to corrosive media. Power generation facilities use cobalt-based hardfacing materials to protect valves and bearings from galling and metal-to-metal wear, reducing costly downtime and extending service life.

FAQs
Cobalt alloys are used in applications requiring exceptional heat resistance, wear resistance, and corrosion protection. Common uses include jet engine turbine blades and combustion chambers in aviation, orthopedic implants and surgical tools in the medical field, downhole tools and valve components in oil and gas, and hardfacing materials for valves and bearings in power generation. Their ability to maintain structural integrity at temperatures above 1000°F (538°C) makes them a preferred choice for high-performance environments.
We supply a range of cobalt alloy grades, including Stellite alloys for wear-resistant hardfacing, L605 for high-temperature aerospace components, and MP35N and Elgiloy for medical devices and fasteners requiring biocompatibility and corrosion resistance. Our application engineering team can help you identify the right grade for your project. Contact us or request a quote to discuss your specifications.
Both cobalt and nickel alloys offer strong corrosion resistance and high-temperature performance. Cobalt alloys generally provide superior wear resistance and better thermal fatigue resistance, making them ideal for hardfacing and components exposed to metal-to-metal contact. Nickel alloys are often preferred where a wider range of heat treatment options or higher tensile strength at moderate temperatures is needed. Stainless Steel Products stocks both families and can advise on the best fit for your application.
