Abratig Co1
Filler metal Cobalt grade 1
Product description
Cobalt-based filler metal, Stellite Grade 1*, for Argon gas or oxyacetylene flame-protected TIG hardfacing of parts subject to combined or unrelated wear: abrasion, metal-to-metal friction, corrosive environments at temperatures from 500°C to 800°C, and occasionally up to 1100°C.
Product application instructions
This filler metal is commonly used for hardfacing components such as valve seats, wire guides, rubber and plastic mixers, extrusion screws and conveyors, where high resistance to wear and heat is required.

Why choose ABRATIG Co1 filler metal?
ABRATIG Cobalt Grade 1 filler metal is recommended for specific applications requiring exceptional mechanical properties and wear resistance. Here are the main reasons for its use.
- Excellent resistance to hot and cold abrasion
TIG Cobalt Grade 1 offers outstanding abrasion resistance at both high and low temperatures, thanks to its composition rich in cobalt, chromium and tungsten carbides.
- Low coefficient of friction
This filler metal has a low coefficient of friction, reducing sliding wear and improving the service life of components subjected to relative movements.
- Erosion and oxidation resistance up to 1000°C: TIG Cobalt Grade 1 maintains its mechanical properties and oxidation resistance at high temperatures, making it ideal for thermally demanding environments.
It is important to note that ABRATIG Cobalt Grade 1 is less suitable for applications involving high impact or requiring crack-free welds, due to its high hardness and potential susceptibility to stress cracking.
In short, TIG Cobalt Grade 1 is chosen for its ability to provide superior protection against wear, abrasion and oxidation at high temperatures, making it ideal for demanding industrial applications where these properties are essential.
