Tungsten market off season ended last week, the flowing trend is unobvious, market is in an intensive situation. Demand still doesn’t increase. Tungsten market volume of business keeps decrease, most enterprises hold wait and see attitude for tungsten market.

Tungsten market not only needs demand but also stability of market. Last week, some enterprises sell the price below market level which is challenging the confidence of market. However, volume of business is still small.

Last week, tungsten products price changes originates from ammonium paratungstate, the mainstream enterprises maintain stable quotation. Some large metallurgy factories say that due to the cost of raw material, ammonium paratungstate price won’t decrease in the next few weeks. APT quotation stays 105~107 thousand RMB/ton. Some other enterprises show that they have advantages both in raw material cost and manufacturing cost. In order to sell the product intiative, quotation maintains at 103~105 RMB/ton, but the selling amount is negative.

Today the indicative price by Ganzhou Tungsten Industry Association, China Minmetal and Jiangxi Rare Earth and Rare Metals Tungsten Group Corporation will come out. It will indicate market price and keep the mainstream stay positive. The indicative price is mainly based on support market confidence, it will be a bit higher than spot market.

The future market trend will greatly depend on this week. It will either turn splendid or fade away. Break weak balance of market is easy, but there is no one who will intervene market balance. Although supply and demand are the most important factors, tungsten price is already below the cost level which is unchangeable. We predict that in short times market will turns weaker and stay stable in the whole as a whole. Dynamic of large enterprises is a key to market, once the stimulus appears, to promote and develop the market is not difficult.

China's new generation carrier rocket "Long March VII"; in at 20:00 on June 25, 2016 the entire spaceport Wenchang in Hainan successfully launched. Long on the 7th is the near-Earth orbit carrying capacity of China's largest rocket, its first flight as China's manned space project Spacelab mission phases starting gun, flush China Aerospace multiple records, opened a new chapter in China's rocket development.

June 25, Beijing time 20:00 sharp, a bright orange light pierced the darkness shrouded in Hainan Island, along with the roar of the engine, a 53 m long rocket into the sky.

In the past few years, the number of rockets launched by China increased significantly, but this rocket because of four reasons unusual. Firstly, it is the Long March series VII first rocket, the Long March rocket VII advent to carry with multifunction cabin space station to orbit. Secondly, since it is built in Wenchang, Hainan Cosmodrome launch of the first rocket. Hainan Wenchang launch site will become China's future space exploration space program base. Again, rocket engines using tungsten copper nozzle . Finally, this is the first rocket to visitors disclosed.

In this sultry June evening, thousands of people gathered in the center of the large for viewing platform launch, a much-anticipated rocket into the sky. Rockets Yiqijuechen cheers of the crowds, began its 394 km above the surface of the journey.

Tungsten copper alloy used in the aerospace missile, rocket engine nozzle, gas vane air rudder, the nose cone, the main requirements are high temperature (3000K ~ 5000K), high-temperature airflow flushing capacity, the use of copper at high temperatures the formation of volatile cooling sweat role (copper melting point 1083 ℃), reducing the surface temperature of tungsten and copper, to ensure use in high temperature extreme conditions.

August 16, China at the Jiuquan spaceport launched the world's first quantum communications satellite "Mo Number." US and Russian experts say, quantum communication is the best choice to ensure information security and defense hackers. "Mo Number" is a phenomenon of quantum entanglement satellite. Quantum entanglement obscure abstruse problems, and even Einstein chanting "Just Like Ghostly."

China's annual spending on space projects expected to be about $ 6 billion, although more than Russia nearly $ 1 billion, but still far less than the $ 40 billion the United States. Although the United States in the space program ho throw tens of billions, but in 2013, only the United States successfully launched 19 rockets; the same year, China launched 14, Russia launched 31. From the data, China clearly has a place in space, and in the future will only grow stronger.
