Pure Tungsten Bar
99.95% tungsten bars
3. Pure Tungsten Bar has been widely used in various tungsten electrodes, printer needles, support wires, lead-in wires, quartz furnace heating devices, filaments, high-speed steel, welding, etc.
The special properties of tungsten rods include low thermal expansion, good thermal conductivity, sufficient electrical resistance, high elastic modulus, etc.
The tungsten bars with a purity of 99.95% are used primarily to cast raw materials for ingredients and forging special steel and drawn steel wires.
