Hyperion Materials & Technologies has over 60 years of experience in the development, manufacturing, and application of corrosion resistant cemented carbides (also known as solid carbide or tungsten carbides (WC)). Conventional cobalt bonded cemented carbides can be used in many applications facing extreme wear or high mechanical stress, but they offer limited corrosion resistance in working conditions where there are severe abrasive or corrosive requirements. Generally, straight tungsten carbide-cobalt (WC-Co) grades are resistant to corrosion down to pH 7.
In most corrosion-wear resistance situations, nickel bonded cemented carbide (WC-Ni) grades that are resistant down to pH 2 to 3 are better choices. For applications with pH down to 1, alloyed TiC-Ni is a solution, but it is more brittle than WC-Co or WC-Ni grades.
Hyperion’s expertise gained over more than 50 years of developing corrosion resistant carbide grades gives us the unique ability to partner with you to select the optimum cemented carbide grade. In addition to corrosion resistant grades, Hyperion offers cemented carbides that are compliant with certifications for food and pharmaceutical manufacturing processes. This includes the following:
