By nature, pure tungsten is a malleable and flexible metal, but in the presence of minute impurities of carbon it becomes incredibly hard. Because of its chemical resistance, it does not interact with nitric, hydrochloric, or any other mixture of acids. To make the metal react with acids, it must be heated, then tungsten dissolves with «aqua regia» and interacts with chlorine or sulfur.

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.
