Technical characteristic

Hafnium cathodes have high strength, elasticity, low coefficient of expansion, resistance to thermal shocks. Under normal conditions, this metal does not react with chemicals, the strength of this material is slightly inferior to tungsten, but much easier to process. These advantages of molybdenum electrodes allow their use in many areas.

Use

Electrical engineering, plain glass manufacturing, optical glass and fiberglass manufacturing, metallurgy of rare earth metals.

Welding

Developed hafnium based thermochemical cathodes for plasma cutting in oxygen. Hafnium welding cathodes produce smooth, high-strength welds while the elements to be joined may have different chemical compositions. The main purpose is to weld low-carbon steel and refractory metals. Electrodes of this type proved to be almost four times more resistant than tungsten electrodes. It should also be noted the high economic effect of using Ta-Hf alloy for the electrodes of air-plasma and oxygen-flame cutting of metals. The alloy contains: additives of tungsten, tantalum, silver, cesium, chromium. Compared to pure hafnium it has a ninefold service life.
