Tungsten Rolled Metal
The main property of tungsten products is increased refractoriness; tungsten melts above a temperature of 3395 °C. This metal has now become the basis for non-melting, electrodes, the main requirement for which is maximum strength and heat resistance. The plasticity of tungsten can be increased under the influence of high temperatures. The range of rolled products includes:
- bars, sheets and strips;
- foil and wire;
- mirrors, tubes and other products.
All offered products are certified. The technical documentation includes data on the chemical composition and specifies the limiting percentage of impurities. The supplier " Evek GmbH ", delivers tungsten tubes, wires, circles, sheets of standard and non-standard sizes at an affordable price in an optimally short time from warehouses. The price of tubes, wires, circles, sheets corresponds to the high quality of the products.
