Tungsten wire is made by forging and drawing tungsten rod step by step, until we get the required diameter. Tungsten filament diameter as thin as 0.02mm are acceptable.
Tungsten wire filament properties are high melting point, high density, high strength, big resistivity, low vapour pressure, slow vapour speed, high temperature resistance, good abrasive resistance, and good acid & alkali resistance ect.
Tungsten filament wire is applied in high temperature furnace as the heating element. In optical instrument & chemical instrument industry, tungsten wire helps a lot too. Tungsten wire is also widely used as light in lighting source.
For the twisted tungsten wire, it is twisted by few tungsten wire. Each tungsten wire with small diameter, and twisted them as a rope. The twisted tungsten wire are made by different special mould according to the shape.
Tungsten wire, molybdenum wire, stranded tungsten wire, tungsten heater, molybdenum heater, tungsten wire rope are our products.
At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department.
