Product Code : AL-WCu-W50Cu50-SF
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Tungsten Copper Strip is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine.
ATT is a professional supplier of Tungsten Copper Strip. We also produce disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.
