Supplier — AvekGlob Company — offers at affordable prices from the manufacturer a sheet and rod made of copper-tungsten alloy VD-20 (CW80). The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

The alloy VD-20 (and its closest foreign analogue CW80) belongs to the number of heat-resistant copper-tungsten alloys. They are produced by pressing, sintering and melting tungsten with copper or silver. This gives the final product the required accuracy with minimal porosity. This alloy is well suited for machining carbide matrices, and also provides greater stability in cutting refractory metals and alloys

Urgency of application

Typical applications of this alloy are rubber welding processes, heavy-duty welding electrodes, where the required pressures are relatively high. The alloy is effective for banding electrodes of electroplating machines. It is also suitable as a material for electroheating of non-ferrous metals and low-carbon steel or for transverse welding of wires and rods of large diameters.

Widely used alloy VD-20 (CW80) was received as a material for electrodes of electroerosive and electrochemical machining, especially when thin surface treatment, deep narrow slits or ribs and small precise holes are required. When using this alloy, the stability of the process is increased, the wear of the tool is reduced, the downtime of the equipment is reduced because of the changeover.

Chemical composition

The composition of the tungsten-copper alloy VD-20 (CW80) includes 80% of tungsten and 20% of copper. Traces of iron and nickel are allowed.

Physical and mechanical properties

• Density, kg / m ³ — 15100;
• Hardness according to Rockwell (scale B) — 94;
• Coefficient of thermal conductivity, W / megade — 44;
• The limit of time resistance, MPa — 662.

Assortment and application features

The sheet and rod of tungsten-copper alloy brand VD-20 (CW80) are produced in any assortment of thickness and diameter of the cross section, which are determined by the requirements of the customer. The machining corresponds to the modes for cast iron. The use of cutting fluids is not required. The material allows a surface coating of silver or copper, soldered in an atmosphere of hydrogen.

Supplier — AvekGlob Company — offers to buy at affordable prices from producers a sheet or rod made of tungsten-copper alloy VD-20 (CW80), in a wide range of cross-sections and cross-sections. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
