Cobalt Alloys

Against abrasive and sliding surfaces, cobalt alloys provide extreme wear resistance. With excellent strength, even in high temperatures, these materials withstand tough, thermal environments.  

Designed for corrosive settings, cobalt alloys are commonly used in the marine, petrochemical and aerospace industries across a variety of applications, including fasteners and bearings. As a biocompatible material, these alloys are periodically in medical prosthetics as artificial joints, hips and knees, as well as dental implants.

At United Titanium, we stock two types of cobalt-based multiphase alloys: UT35N and UT98T. While both yield high strength, UT35N attains an impressive tensile strength of more than 300 ksi. A superalloy, UT98T adheres to the critical requirements necessary for naval marine fasteners.
