**Cobalt Alloy 6B Bars and Rods** are primarily made up of cobalt (about 60%), along with chromium (28–32%), tungsten (3.5–5%), and smaller amounts of molybdenum, iron, and carbon. This alloy is known for its outstanding resistance to wear, galling, and corrosion, even under high temperatures. It boasts a tensile strength of around 965 MPa and can reach a hardness of up to 45 HRC in its annealed state. Cobalt 6B retains its mechanical properties across a broad temperature range, making it perfect for extreme service conditions that involve friction, pressure, and thermal cycling.
