What is Cobalt Base Alloys CO25 Filler Wire?

The Co25 Filler Wire is mainly made up of cobalt (about 52%), chromium (20%), nickel (10%), and tungsten (15%), with small amounts of iron and carbon. This alloy shines with its impressive high-temperature strength, oxidation resistance, and wear resistance, even at temperatures reaching 1000°C (1830°F). It typically boasts a tensile strength of around 145–160 ksi and retains excellent toughness, even in challenging thermal and corrosive environments. The wire excels in TIG and plasma arc welding, creating smooth, defect-free welds with a low risk of cracking, making it suitable for both fabrication and overlay tasks.
