Technodur & Technosphere

Technodur® and Technosphere® are made up of a nickel core wire, coated with a thick layer of Tungsten Carbide and Ni Cr B Si alloy. They are applied using Oxy-Acetylene welding.

The difference between Technodur® and Technosphere® lies in the use of spherical Tungsten Carbide grains (Spherotene®).

The spherical shape and extreme hardness of Spherotene® gives Technosphere®, amongst other properties, two main advantages:

Good shock resistance
Unequalled wear resistance

This type of welding is easy, economic and also offers the major advantage of preserving the hardness of the Tungsten Carbide particles, which would not be the case if using other welding processes.


Can be applied to all non-martensitic steels and weldable stainless steels. Can be welded easily onto itself for refurbishment of worn parts.

Can be applied in-house by our trained personnel to your free issue parts, or is available on 5kg or 20kg coils for your own application.
