Technical Characteristics

W-Co alloys are of most practical interest nowadays due to their high hardness and wear resistance, especially at high temperatures, as well as their special magnetic properties.

Chemical stability

W-Co alloys are chemically very resistant even at low levels of tungsten (up to 20%). Their resistance to acids is greater than that of cobalt or nickel: in nitric acid they dissolve 2.2 times harder than nickel and 14 times slower than cobalt; in sulfuric acid their resistance: 3.6 times higher than nickel and 32 times higher than Co.

Coatings

W-Co alloy coatings successfully replace hard chromium coatings. Besides, hardness of W-Co coatings after heat treatment for 1 hour at 600 °C increases almost twice.
