What is Cobalt Filler Wire?
Typical composition of a cobalt filler wire would be a combination of the principal element Cobalt (balance with), Chromium 25–32%, Tungsten 4–6%, Nickel ≤3%, Carbon 1.5–3%, Silicon ≤1%, and Iron ≤3%, depending on the alloy. There is significant hardness (38–47 HRC), high-temperature strength and wear resistance, and thermal-mechanical stability in combination with heavy thermal and mechanical loadings. Cobalt filler wires exhibit superior resistance to corrosion & oxidation, abrasion, and galling, amongst other qualities, and are suited to industrial and heavy-duty circumstances. The combination of toughness and durability of cobalt filler wires results in a long service life of components exposed to friction, impact, and increased temperatures, and can be manufactured to provide balance of hardness and toughness for aerospace energy and heavy industry.

Cobalt Filler Wire Uses
Cobalt filler wire is widely utilized in hardfacing, overlay and repair welding applications where wear, corrosion and heat resistance are essential. Cobalt filler wire is particularly effective for valve seats, turbine blades, pump parts, dies, cutting tools, and bearing surfaces that experience extreme levels of abrasion, impact, and high temperature. Cobalt filler wire finds common application across aerospace, power generation, petrochemical and mining industries because it provides high wear resistance and performance of new or used equipment. Cobalt filler wire is a great choice for your application because of its incredible hardness, toughness, oxidation resistance and galling resistance therefore protecting valuable equipment from the elements and extreme conditions providing service longevity.
