With the gradual recovery of the global economy, the demand for global aviation aircraft will be huge in the next few years. According to the forecast of Airbus and Boeing in the next 20 years of the civil aviation aircraft market, the global civil aviation aircraft market will reach 5.6 trillion US dollars in the next 20 years.
In 2019, the steady supply of tungsten in the market will continue. The price of tungsten concentrate is affected by the decline of resource grade, rising cost, increased safety and environmental protection pressure, and the space for decline is small
China's tungsten industry has generally maintained a stable operating situation. The output continued to grow steadily, the export remained high, the price fluctuated slightly, and the economic benefits of the company continued to improve.
Since 2018, the tungsten industry has generally maintained a stable operation.The output of major products increased steadily. From January to November, the national tungsten concentrate production was 105,000 tons (WO365%), up 2.8% year-on-year;
The powder particle size and uniformity of tungsten powder and copper powder will affect the sintering effect of tungsten-copper alloy electrode to a certain extent. The reduction of powder particle size will make the comprehensive properties of materials such as density, hardness etc.
The morphological distribution of the tungsten-copper powder sintered material is uniformly distributed on the copper substrate with tungsten as a skeleton. Due to the high melting point and high hardness of tungsten W, the ultimate tensile strength of tungsten at 1000 ° C is still 50kgf / mm2
Tungsten industry situationIn in the first three quarters of this year, China's tungsten industry generally maintained a stable operation. The output continued to grow steadily, the export remained high, the price fluctuated slightly, and the economic benefits of the company continued to improve.
