One of the most adaptable materials for wear components is tungsten carbide (TC). It provides the following advantages:
High mechanical strength and hardness, superior wear resistance, good corrosion resistance, and the ability to handle abrasive services (Good fracture toughness)
There are six different types of tungsten carbide available, including nickel- and cobalt-bonded varieties.
Cobalt-bonded TC offers higher hardness and better abrasion resistance than nickel-bonded TC does, while nickel-bonded TC and cobalt-bonded TC both give enhanced corrosion protection.
The following grades are available
- 6% Nickel bonded TC
- 6% Cobalt bonded TC
- 8% Nickel bonded TC
- 8% Cobalt bonded TC
- 10% Nickel bonded TC
- 10% Cobalt bonded TC
