FCW 6BC-G
Cobalt-based cored wire grade 6 low carbon
Product description
Combines all the outstanding properties of cobalt-based products, such as resistance to corrosion and erosion at cold and high temperatures. FCW 6 BC is an alloy equivalent to FCW 6-G but with less carbon. It is less hard, but easier to machine and less susceptible to cracking than FCW 6-. The product is welded both automatically and semi-automatically.
Used on seats, corners, gates and directly in the body of valves and cylinders.

Why choose this cored wire?
- Exceptional resistance to metal-to-metal wear
Grade 6 is renowned for its anti-seize properties. In the low-carbon version (FCW 6BC-G), it retains this wear resistance while being less susceptible to cracking, especially on complex geometries or in multi-layers.
- Better toughness and lower risk of cracking
Reduced carbon → fewer carbides → more ductile structure, allowing greater absorption of mechanical or thermal stress without cracking. Perfect for:
-thin parts,
multi-layer reloading,
-welded parts on sensitive steels.
- Good heat resistance (≈ 800 °C)
Like the standard version, it retains its hardness and high-temperature resistance, making it an ideal alloy for valves, valve seats, hot-cutting tools and more.
- Excellent resistance to corrosion and oxidation
The cobalt-chromium base offers natural protection against chemicals, humidity and heat oxidation, without the need for additional treatment.
