Why choose this cored wire?
- Excellent resistance to abrasive and adhesive wear
FCW 12-G is harder than FCW 6-G yet less brittle than FCW 1-G, making it versatile for parts subject to both :
-light to moderate abrasion,
-slippage under load,
-moderate shocks.
- Excellent high-temperature resistance
It retains its mechanical properties up to 850-900°C, making it ideal for valve parts, valve seats, cutting tools, or parts exposed to severe thermal cycling.
- Good compromise between hardness and toughness
With a typical hardness of ~44-47 HRC, it resists wear well while remaining tough enough not to crack easily, even after several passes or on complex geometries.
- Excellent resistance to corrosion and oxidation
The tungsten-alloyed cobalt-chromium base provides excellent resistance to slightly corrosive environments and hot oxidizing conditions, prolonging part life.
