Tungsten Price Increasing begin end May

As professional news releaser in China, CTIA has gathered information from its members about the price of tungsten raw material. As trend in China, the price of tungsten raw material is expected to be increased. Untile, most tungsten ores owner has kept their stock and remain its standing attitude for the final tungsten price trend, but as for their un-certainty, the price of middle products, such as tungsten trioxide, etc has been popular products for customers. As a result the price has been staying increasing trend. And most manufacturer’s production schedule has been so tight. 

Today, the tungsten price of YTO 0.6~1.8 is being 42.50 USD/KG, and 12~20um has been 39.00USD/KG.

Tungsten Ribbon

Tungsten ribbon is shaped like tungsten foil with long length, and bright surface. Ribbon made of tungsten is with high density, high purity and high melting point.

Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten directly translatable to heavy stone though the name is volfram in Swedish to distinguish it from Scheelite, which in Swedish is alternatively named tungsten.

A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds. It was identified as a new element in 1781, and first isolated as a metal in 1783. Its important ores include wolframite and scheelite. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the elements. Also remarkable is its high density of 19.3 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Tungsten with minor amounts of impurities is often brittle[5] and hard, making it difficult to work. However, very pure tungsten, though still hard, is more ductile, and can be cut with a hard-steel hacksaw.

Surface of Tungsten Wire

Tungsten wire can be purchased according to the surface condition, black or cleaned.
The above picture is to show the surface of tungsten wire is cleaned.

The applications of black or cleaned tungsten wire are for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and evaporation sources in metallizing processes. Thicker sizes of tungsten wire, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal lead parts in the lighting and electronic industries.

Tungsten Granule Order Process

Tungsten granule is made of pure tungsten material with irregular particles. Tungsten granule is also called tungsten flux, tungsten accelerator, and tungsten granulate. The purity of tungsten granule can reach 99.90% or 99.95%min. The color of tungsten granule is metal bright. Tungsten granule is mainly in welding rod, carbon sulfur analysis, weight filler, radiation shielding filler,welding fitting, induction accelerator, etc.

Most Popular Sizes of Tungsten Granule

The most popular size of tungsten granule is -20~+40mesh.
