Tungsten Carbide Seal

Tungsten carbide seal is made from the main component of high hardness refractory metal (WC, TiC) powder, add the related additives of Co, Ni or Mo. After pressing, and then sintering in vacuum furnace or hydrogen reduction furnace.

Tungsten carbide seal with excellent properties of high hardness, wear resistance, strength and toughness, high heat-resistant and corrosion-resistant. Even if in the temperature of 500℃, the products will also keep unchanged, and will have very high hardness in 1000℃.

Tungsten carbide seal consist of two parts, a part is hardening phase, and another part is Binder metal. Tungsten carbide combined seals ring is kinds of seals consist by two or more than two seals, which is in order to reach desired sealing effect. The types of seals include three seals, five seals and so on.

Tungsten Carbide Seals

Tungsten carbide seals are extremely tough and stiff and have very good abrasion resistance. Tungsten carbide seals have versatile seal faces like silicon carbide. Tungsten carbide seals are very hard like silicon carbide seals, however they are very heavy to the touch, making them easy to distinguish from silicon carbide.

There are various types of tungsten carbide seals, such as single-spring seals and double-spring seals. Special tungsten carbide seals are available with the customers' drawings provided. Please do not hesitate to contact us if you have any questions.

Advantages
Tungsten carbide seals are excellent with resistant-wearing, high fractural strength, high thermal conductivity, and small heat expansion co-efficient. Tungsten carbide is the best material to resist heat and fracture in all hard face materials.
Tungsten carbide seals are ideal for high pressure applications due to a high modulus of elasticity which helps prevent face distortion.Tungsten carbide also can be re-lapped and polished to be re-used.
