Cobalt-base alloys offer high hardness& hot hardness and excellent high-temperature strength, and have excellent thermal fatigue resistance and thermal shock resistance, besides they are resistant to antioxidant, corrosion, grain abrasion, and metal abrasion. The alloys are applied under the abrasion resistance, high-temperature resistance, and thermal shock resistance conditions, to manufacture, repair and protect various types of spare parts. The products categories include cobalt-base welding sticks, cobalt-base alloy power, cobalt-base electric welding rods, cobalt-base precision castings, and wrought alloys.
