Tungsten Nut

Tungsten nut is made of tungsten with purity over 99.95%, and density over 19.0g/cm3 which is to connect two machinery parts with inner holes by its thread and applied with tungsten bolt. Mostly nuts are hexagonal nut and quadrangle, and has been standard specifications. Currently, there are more generic GB (GB), German standard (DIN), International Standards (ISO), the Japanese standard (JIS), American Standard (ASTM / ANSI). Among them, the national standard, German standard, the standard represented by M (for example, M8, M16), American, British is expressed as a fraction or # size (such as 8, # 10, 1 / 4,3 / 8).

Properties of Tungsten bolt

Tungsten bolt is a very important bolt, which is mainly used for high temperature furnace, sintering furnace, furnace and other high-temperature environments. The main reason is because tungsten owns properties of high temperature resistance, whose melting point can be up to 3410 ℃. During use, tungsten bolts should be paid attention to their fragile characteristics, which is not suitable for use in high-intensity vibration machines, but more suitable in a static environment.

Tungsten bolts are also having different standards, such as American, British. The choosing of the standard should come to their match machines.

Tungsten Bolt

Tungsten bolt is a fasten part used to combine the head and thread bolt. This is not a separate part during using in the machine parts, it should be used together with screw and for the center hole mechanical parts screwed together. There are many types of bolt head, can be straight line, hexagonal, etc.
Bolts, also known as a screw, bolt screws, or called be called fasteners directly. It is mainly applied the principles of physics and mathematical slant circular rotation and friction, and is a gradual tightening artifacts mechanical tool.

Bolts are widely used in daily life and industrial production, which is also known as the rice of industry. Bolts are mainly used in electronic products, machinery products, digital products, electrical equipment, machinery and electrical machinery products. Ships, vehicles, water conservancy, even chemistry experiment are also applied bolt. Other applications, such as double-precision bolts used in DVD, cameras, eyeglasses, watches, electronics, micro bolts, large bolts used in television, electrical products, musical instruments, furniture and other general bolts.

Tungsten Tube

Tungsten tube, also named wolfram tube is a main product of pure tungsten products, which is making with purity of 99.95%min. meanwhile, its density can be higher to 18.2g/cm3 for sintering and 19.2g/cm3 after swaging. With its high density, the product is widely used as shielding material. As for the material is also with tungsten properties, high melting point, high boiling point, high temperature resistance, corrosion resistance and low thermal expansion. The tube can be used as pipe in melting other metals.

Tungsten tube is making according to GB/T 4187-1984 in Chinese standard and international standard of ASTM F288-90. The physical and chemical properties can reach the attached parts as the basic standard.
