Copper-tungsten pseudoplane
Supplier — AvekGlob Company — offers copper-tungsten pseudoalloys at an affordable price in the assortment of brands and profiles. The supplier guarantees the timely delivery of products to any address specified by the consumer /
Technical specifications
Copper-tungsten pseudoalloys are powder particles of pure tungsten, suspended in a matrix of copper. These materials are known for good thermal conductivity, electrical conductivity, low thermal expansion and resistance to electric arc erosion. Thus, they are often used as electrical contacts, especially in applications with high voltage.
Most sizes and shapes can be shipped with a short lead time.
Urgency of application
The operational advantages of copper-tungsten pseudoalloys are:
High resistance to the arc in combination with good electrical conductivity;
High thermal conductivity;
Low thermal expansion.
In connection with this, the materials in question are used for the production of arc and vacuum contacts in high-voltage or medium-voltage switches or vacuum choppers, electrodes in processes and equipment for electroerosion processing, radiators for passive cooling of electronic devices, and electrodes for contact welding.
Chemical composition
The composition of tungsten-copper alloys of foreign production usually includes from 55 to 90% of tungsten and, accordingly, from 45 to 10% of copper. Traces of iron and nickel are allowed.
