Wear Protection / Powder

Powders for surfacing machine parts which are exposed to high wear, corrosion and heat resistance. Alunox provides inert atomized metal powders on Fe, Ni and Co based analyses and according to specification. The available grain sizes - mainly 180-20 microns - cover all uses in traditional processing methods such as PTA, flame spraying and HVOF. Our focus lies on corrosion and wear protection. The goal is especially to increase the service life of highly stressed machine parts and their protection against corrosion. For more information, please get in touch with us.

Cored Wire for Wear Protection

(see also menu item "Cored Wire")

We supply flux-cored hardfacing wires in diameters of 1.2 to 4.0 mm. Our standard product range includes Ni, Fe, Co, and Al-based alloys. Furthermore, we can manufacture cored wires according to your specifications.


C-, CR-, WC- alloyed cored wire

C-, Cr-, WC-alloyed flux-cored wires are used everywhere where parts are exposed to highly abrasive wear. The weld metal is hardly machinable by metal cutting. Owing to the corrosion resistant alloy matrix, the weld metal is suitable for use in wet areas. Typical applications: mixer blades, concrete gland packings, lime breaker mills, screw conveyors, plows for agriculture as well as applications in the metallurgical industry. For higher corrosion resistance, an alloy with higher Co content should be used.


C-, Cr-, Ni-, V-, Mo-alloyed cored wire

C-, Cr-, Ni-, V-, Mo-alloyed cored wires are suitable for surfacing parts which are subject to wear and friction and exposed to impact stress. The weld metal is corrosion resistant and easy to grind with CBN. This of type of cored wire is found in mining, for example in plots on bucket wheel excavators, chutes, conveyor troughs and chassis units.
