仕様
tungsten bar stock Content 99.95% 99.97% Density: 19.3g/ cm3 Dia: 2.5-120mm Type: lathed, centerless, forged or etched.
Whether for injection molding, in the field of device and machining technology or in the lighting industry: Our rods made tungsten and tungsten alloys excel due to their outstanding material purity and constant high quality.
We place the emphasis on absolute precision during the production of our rods. We insist on particularly low tolerances in terms of both diameter and roundness and guarantee rods of exceptional straightness. With our state-of-the-art production equipment and many years of experience in the field of refractory metals, even tungsten rods of diameters of up to 90 mm are no problem for us. On request, we can also supply tungsten rods in larger dimensions.
Because we manufacture our tungsten rods from especially fine-grained materials, ease of forming and machining is guaranteed. Our range includes a number of different surface qualities: lathed, centerless, forged or etched.
Product Description
Tungsten has the highest melting point of all metals. Tungsten rods are mainly used in the lighting industry and high temperature furnace construction.
