Tungsten market trend is steady since last week with small transaction volume of tungsten products. The devaluation of RMB which hits 6.7 also affect tungsten price. Tungsten market is expected to be stable in the rest two months.

A new material that emits short-wavelength thermal radiation when heated could be used in systems that convert waste heat into electrical energy. Created by an international team co-led by researchers at Purdue University, the University of Alberta and Hamburg University of Technology, the material comprises alternating layers of 20 nm of tungsten oxide and 100 nm of hafnium oxide.

Tungsten oxide is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals. Tungsten ores are treated with alkalis to produce WO3. It is insoluble in H2O and acids, but soluble in hot alkalis. It is n type semiconductor material, the special physical and chemical property make it used in various filed and become the important functional material in modern scientific research.

The structure was chosen so that the emission of long-wavelength infrared photons from the material is suppressed while the emission of shorter wavelength photons is enhanced. These shorter wavelength photons have enough energy to drive a photovoltaic cell, while the longer wavelength photons do not. The research team tested the material by heating it to 1000˚C and using it to power a photovoltaic cell. They found that the new material produced 90% more electrical energy than a conventional black-body infrared emitter. It could someday be used to generate electricity from the waste heat produced by industrial processes and even automobile engines.

The age of immersion is a kind of experience, such as VR, which can make outsiders be immersive in what happened. This technology has found live in daily life for everybody.

Transportation applied mobile internet is a part of immersion phenomena, such as working in car, alive meeting, transferring files in long distance. Every driver or passengers can screening what they come across, and use mobile or other equipment to transfer for others who are not in the same place, so that they can have an experience the same. It is like a game that the characters are playing as real human beings.

Digital community one-stop service is also applied the same technology. More and more community services, intelligent buildings, supermarket, after-sales service, pipeline repair, travel services, film culture, etc. are using electronic method to spread, which can reach a goal of off line and on line service for communities. More details can be found as water, electricity, pineline repair and other comprehensive information can share by internet, which means households can pay the fee or call for repair teams by a phone or by computer directly, and with immersion technology, the service can be customized.

Digital square is an immersion service for public. Images and videos showing on transportation hub, airport, railway station, bus station, office building, shopping mall, gas station, fast food restaurant, fitness center, port, square for public, which can show for more people are also applied the same technology. Experiencor can use virtual technology to feel what they see, to be a participant but not an outsider. This technology is in-time and thorough.

For tungsten, using immersion technology is a challenge, buyers can experience the part they buy, to know the processes what their parts is processing out, to know what the parts pack, to know what the parts deliver… they are not only a person buys the product, but knows what the processes for this part.

Invention and application of modern tungsten carbide materials is the change of  history material, which known as the "industrial teeth", fully reflects the ability of human transformation of nature with tools to enhance the material and improve.

Tungsten carbide tool as a cutting tool, widely used in all aspects of modern manufacturing, with its excellent performance is to guide the high-quality metal cutting market development. China's consumption of cutting tools, about 69% of high-speed steel cutting tools, carbide cutting tools accounted for only about 28% (the rest of the tool system, diamond and cubic boron nitride cutting tools, etc.). Even with the import of tools, cutting tool consumption in China, about 53% for high-speed steel cutting tools, and carbide cutting tools for 45%, while the diamond and cubic boron nitride tool only 2%. The proportion of the world's cutting tool consumption is probably: high-speed steel cutting tools accounted for 35%, 10% of diamond and cubic boron nitride cutting tools, while the welding carbide cutting tools, solid carbide and carbide can be indexed the rest section.


 

This shows that the cutting tool market in China's tool consumption structure can not reach the world average. We can see China as the world's largest metal cutting market its overall level is not enough, high-end carbide cutting tools is not yet developed. This is for the production of carbide is a big country vigilance!

The overall low level of processing and our rising labor costs and the appreciation of the renminbi have hidden the risks of making our Chinese manufacturing less competitive. Economists and entrepreneurs in some countries, including the United States, are considering Will have moved some of the manufacturing enterprises in Asia moved back to their home. To enable us to continue to attract global enterprises to land manufacturing in China, we need to improve our competitiveness, including, of course, improve the manufacturing level. But also in line with the CPC Central Committee on our "second Five-Year" period to change the mode of development requirements, that is, from the number of low-value, high consumption of manufacturing, to the heavy level, high value-added, green manufacturing.

Direction of development for cutting tool market must be high value-added, high-performance carbide cutting tools and other high-end superhard cutting tools become mainstream, high-speed steel and other traditional materials, tool overcapacity, performance and other factors is restricting China's high-end carbide Tool development is an important bottleneck.
