Tungsten Bracket for Sapphire Growth Furnace

Tungsten bracket is also called tungsten support for the set products of tungsten crucible. The shape of tungsten bracket is always round with hole in the middle. The purity of tungsten bracket is over 99.95%, and its density is about 18.2g/cm3, which can be the same as tungsten crucible and tungsten crucible cover.

Tungsten crucible connected with tungsten bracket and tungsten crucible cover is a set of products in the middle of sapphire growth furnace. All these products are sintered and smoothed. Tungsten crucible cover and tungsten bracket can also be polished, which is showing the bright and smooth surface.
The main reason for tungsten used as the material for tungsten bracket is high temperature resistance.

Tungsten Crucible Cover for Sapphire Growth Furnace

As for the properties of high density, high temperature resistance, high melting point, tungsten crucible is a main part of sapphire growth furnace. Tungsten crucible cover is one part of tungsten crucible. The tungsten crucible for sapphire growth furnace is used the material of tungsten with the purity over 99.95%. Mostly, tungsten crucible cover is sintered, and its density is about 18.3g/cm3. Besides tungsten crucible cover, the set products include tungsten crucible base, or tungsten tray.

As the heat shield parts of sapphire growth furnace, the most important efforts made by tungsten crucible cover and tungsten heat shield are sealing the products inside the furnace and keeping the temperature inside. Tungsten crucible cover is hgh purified, high specifications accuracy, smooth surface condition and reasonale design, which are important for the quality of sapphire crystal.
Tungsten crucible cover and tungsten crucible closely integrated to provide a sealed space for the production of sapphire crystal. The seal of space control is a key factor for the quality of the sapphire crystal sapphire growth.

Chinatungsten Online has proficient experience, and the production of tungsten crucible and tungsten crucible cover and support frame are accepted by the customers, and the most significantly, the quality of tungsten crucible cover can be assured.

Tungsten Crucible for Sapphire Growth Furnace

Tungsten crucible and related tungsten thermal system for sapphire growth furnace owns the properties of high density, high purity and high processing accuracy. Tungsten crucible for sapphire growth furnace is made of the material of pure tungsten, whose purity is over 99.95%, and the density is about 18.2g/cm3.
The manufacturing techniques of tungsten crucible for sapphire growth furnace are sintering, metal forming, spinning type, the use of molybdenum rod turning molding, or welding of a variety of pure tungsten plates, tungsten plates and pure tungsten rod. The tungsten crucible can be used under the high temperature of 2600 degree.



Tungsten crucible is also used in sapphire growth furnace is mainly because of the properties of tungsten, which are high boiling point, high melting point, thigh temperature resistance, high corrosion resistance,low thermal expansion coeffient, and high thermal conductivity. Besides tungsten crucible for sapphire growth furnace, tungsten crucible is also used in metallurgy of rare earth, ion plating and quartz glass.

It is because of the properties of tungsten crucible that tungsten crucible is chose as one important part in the process of growing sapphire crystal. Under high temperature, tungsten crucible will not react with Al2O3, so that the purity of sapphire crystal can be assured.

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.
