High Purity 99.95 Pure Tungsten Wire Polished Surface 1.0mm for Vacuum Metallizing

Pure tungsten is a steel-gray to tin-white metal. Very pure tungsten can be cut with a hacksaw,  forged, spun, drawn, and extruded. The impure metal is brittle and can be worked only with difficulty. Tungsten has the highest melting point of all metals, and at temperatures over 1650oC has the highest tensile strength. The metal oxidizes in air and must be protected at elevated temperatures. It has excellent corrosion resistance and is attacked only slightly by most mineral acids. The thermal expansion is about the same as borosilicate glass, which makes the metal useful for glass-to-metal seals.

Introduction of Polished Tungsten Wire:

5. Features: excellent formability, long life and super lighting efficiency. Mainly used for making various electron tube, H series auto lamp,halogen lamp and other special lamp. 

Applications of Tungsten Wires:

With a high melting point, high hardness and good thermal and electric conductivity, tungsten wire is mainly used in powder metallurgical, lighting, electronics, high-temperature furnace, aerospace, chemical and glass ceramics industries for its heat, abrasion and corrosion resistance and chemical stablilty. 

Appearance:  W-wire is regular black covered with graphite. After graphite is removed it is metallic luster.

Advantages of Tungsten Wire:

•Tungsten has the highest melting point of all metals
• High strength at high temperatures
• Good conductivity for heat and electricity
• High absorption capacity for radioactive radiation and X-rays
