What’s Cobalt Alloy and What Are the Cobalt Alloy Properties?

Cobalt (Co) is a lustrous, silvery-blue, non-ferrous metal found in smaltite, cobaltite, and erythrite minerals. Cobalt alloy is a kind of metal alloys containing cobalt as the base material. Cobalt alloys have excellent high strength and toughness, high-temperature strength and resistance, and good corrosion resistance.

Cobalt alloys made be categorized based on their key material advantages. These include wear resistance, heat resistance, and corrosion resistance.
Stanford Advanced Materials manufactures fasteners from cobalt-based multiphase alloys.

Fasteners made from these alloys offer excellent strength and toughness characteristics. These alloys are designed for use in corrosive applications such as seawater, petrochemicals, aerospace, and medical prosthetics and implants.
The properties of cobalt-based multiphase alloys are as follows:

Heat resistant alloys are those that are made to resist elevated-temperature strength and resistance to thermal fatigue. Although they are not as widely used as nickel-based high-temperature alloys, they play a role in temperatures above nickel’s deterioration point and in applications where sulfidation resistance is important.

Corrosion-resistant alloys are those that are designed to resist aqueous corrosion. They are limited in their corrosion resistance in comparison to nickel-chromium-molybdenum alloys.

However, several low-carbon, wrought cobalt-nickel-chromium-molybdenum alloys exist to satisfy the need for a corrosion-resistant cobalt-base alloy.

Wear-resistant alloys are those that are made to resist abrasive wear, sliding wear, and erosive wear. They consist mostly of cobalt and chromium but may also contain tungsten or molybdenum and a small amount of carbon. Cobalt alloys are widely used in the Stellite field.
