The full name of tungsten carbide alloy industry, also known as tungsten steel, tungsten is the world's one of the hardest metal hardness 8-9M (Mohs hardness standard) between second only to diamonds.

Tungsten Platinum: also known as tungsten tungsten white gold rhodium manufacturing process: the build tungsten gold jewelry and platinum powder molding together into the 3000 degree heat furnace in a vacuum environment for platinum jewelry tungsten powder slowly dissolved , and so that the tungsten gold jewelry to achieve whiter brighter visual effects; from white tungsten to create jewelry, the same with tungsten jewelry hardness, gloss and texture, not color does not wear, but the color than tungsten directly create jewelry whiter, closer to silver.

Tungsten,a metal element, atomic number 74, atomic weight 183.85.Steel gray or silvery-white, high hardness, high melting point, room temperature without air attack; mainly used for the manufacture of the filament and high-speed cutting steel, hard mold, also used in optical instruments, chemistry instruments. China is the world's largest tungsten storage power.
 
Tungsten is part of non-ferrous metals, is also an important strategic metal, tungsten ore in ancient times was called "heavy stone." 1781 by the Swedish chemist Carl Wilhelm Scheele discovered scheelite, and extract new elements acid - acid, in 1783 by the Spanish Air Asia Depp found wolframite also extract the acid, the same year, with carbon reduction of tungsten trioxide first got tungsten powder, and named the element. Tungsten content in the crust is 0.001%. Tungsten minerals have been found in 20 species. Tungsten deposit is generally accompanied by granitic magma activity and the formation. After tungsten smelting after the silver-white lustrous metal, high melting point, great hardness. Tungsten is the highest melting points.

Land and Resources has announced the list of the second batch of 33 mines eligibility for National Mine Park, Chenzhou Mining Shizhuyuan Park and Guiyang Baoshan Mine Park list.

Mine Park is a showcase of human remains of the landscape as the main mining, mining development reflects historical connotations, have research value and educational function, available tour to visit, conduct scientific investigation and scientific literacy of specific spatial zone.
 
China has 61 national parks Mine Park qualification. The unit was awarded the qualification requirements shall be carried out by the Ministry of Land and construction in the park during the two years of construction, the building standards be officially named National Mine Park.

The First Step: An elongated strip through the mold pipe
 
The Two Step : Wegmentation, typically 60mm or 400mm length
 
The Third step: Clear, drying, filling, sealing
 
The Fourth step: Testing, packaging, storage
 
Note: 1, The matrix preheat; 2, Flame size; 3, Welding distance; 4, Electrode angle.
In the process of welding strict compliance: oxygen and acetylene bottles can not be put together in order to prevent dangerous!

State Administration of Taxation reported anomalies appear for export tax rebates recently issued "on the strengthening of some of the goods export tax rebate audit," which called for efforts to strengthen the export tax rebate audit of raw materials such as silver, tungsten circuit parts and raw materials for welding parts products.

Recently Research Ministry formulated the "tungsten, tin, antimony smelting enterprise access Announcement Interim Measures," around the MIIT department of tungsten in the region, tin, antimony smelting enterprise access Announcement application and reported the Ministry of Industry, the experts on the application materials for review, the focus sampling and publicity after the Ministry will publish the announcement in the form of a list of companies fulfill the access conditions.

In 2009, Fujian Science and Technology Awards Conference held on March 16 this year, director of the National Engineering Research Center of tungsten materials, Xiamen Golden Egret Special Alloy Co., Ltd., Wu Chong Hu, vice president of science and technology, Fujian Xiamen Tungsten Co., Ltd. obtained significant contribution Award, outstanding Technical talent Award Fujian Province, Science and Technology Award in Xiamen, Fujian Province, known as the technology sector, "the cow".

Chonghu Wu Xiamen Tungsten Group is one of the founders lifetime in dealing with tungsten is China's leading tungsten smelting and carbide experts and industry leaders have repeatedly presided over the completion of the national "863" plan, the State Torch Program, national key new product plans, national Science and Technology support Program and Xiamen major industrial projects, and achieved significant technological achievements 10 The remainder, patented and national, provincial and municipal science and technology awards a number of inventions.

Chonghu Wu Equipment innovation is still much higher than after the introduction of the transformation capacity to raise the level of 2-3 times the energy consumption is reduced three percent, "which makes top experts in the field of foreign tungsten surprised, they wanted to find ways to buy our equipment," now the world's five largest companies want to stake Carbide spoonbill.
