Spark Erosion & Electro-Chemical Machining

Vaculoy CT72 provides a spark machining material with the properties required when conventional electrode materials erode too quickly. it is particularly suitable for fine finish and sharp definition work, especially when eroding hardened steels and tungsten carbide.

In electro chemical machining it resists damage by spark and electrolyte glow whilst having adequate electrical conductivity.

Resistance Welding

Vaculoy CT75W is a fine grain tungsten copper composite conforming to BS4577-B11. It has a high hardness and resitance to deformation at elevated welding temperature. It is utilised as inserts, electrodes or dies for projection and seam welding, flash butt and spot welding.

Electrical Upsetting

Vaculoy CTC67 is a tungsten carbide copper composite confirmiog to BS4577-B12. It has, because of the use of tungsten carbide, a higher hardness and heat strength than CT75W and is used as dies and anvils in electrical upsetting.
