Due to a high melting point and high corrosion resistance, tungsten heater is widely used in vacuum aluminizing. With the rapid development of electronic information market, high-performance chips, the new display and other electronic devices market has a good development space. The key support of electronics manufacturing is a thin film material, and because of the lower resistivity, and it is easy to deposit, and the mature technology and other excellent characteristics, a thin aluminum film has become core material for integrated circuits, discrete devices, liquid crystal display and other related fields. Compared to developed countries, the time of the development of ultra-high purity aluminum and its alloys evaporation material is relatively late, there is still a certain gap to well-known international companies in process maturity and industry development. Although China is one of the largest countries for reserves of tungsten resources in the world, but due to the immaturity of the technology, tungsten heater cannot satisfy domestic market in vacuum aluminizing. As a result of it, most buyers have to import products from abroad, which would not only time consuming but also a greater cost.

Recently, China News reported that sets of technology system have been established of ultra-high purity aluminum and its alloy coating materials, realizing the development and industrialization of electronic information field the ultra-high purity aluminum evaporation materials, semiconductor of aluminum and its alloy target material and a full range of coating materials. The localization of ultra-high-purity aluminum and its alloy coating materials will accelerate the development of high-end high-purity thin film material, greatly facilitate the improvement of traditional non-ferrous metal industries and industrial extension technology, and prefect the advanced electronic information manufacturing industry and supply chain of accessory products. Vacuum aluminizing has the feature of plastic film and the properties of the metal. The function of vacuum aluminizing is that it can prevent ultraviolet ray, which prolongs quality guarantee period and improves the brightness and perception of film.

Mineral resources are non-renewable resources, due to its limited reserves, China has strengthen the control of it in recent years. It is an important material basis for the development of social production, and production and life of modern society have already cannot separate with mineral resources. Moreover, China is currently in the mid-industrialization, the demand of mineral resources is increasing. China Mining News reported that the Ministry of Land and Resources of the People’s Republic of China made it clear in the near future that China will further strengthen the exploration and protection of important mineral resources. Land and Resources issued the “Land Resources ‘Thirteen Five’ Plan” which focus on the implementation of effective control of mining tungsten, rare earth ions, etc., strictly limiting the development of minerals and tailings resources which cannot be reasonably used, so that it can avoid the destruction and the waste of resources. Strictly managing development access of mineral resources, improving entry barriers of environmental protection, technology, investment, efficiency of resource use and others.

Although China is one of the biggest tungsten ore reserves countries in the world, but because of irrational exploitation and utilization, leading to the depletion of mineral resources. This regulation has the impact on the tungsten market. On the one hand, it would limit the production of the tungsten heater to a certain extent, and now it can ease the problem of oversupply of tungsten market. On the other hand, this plan can improve the development and utilization of mineral resources, protection China’s mineral resources. With the development of China's industrialization process, environmental pollution has also increased year by year, haze, acid rain and other natural disasters annually cause some damage to economy and the environment. This strengthening of controls will slow down the pollution of the environment to some extent.

In recent years, China's economic situation is not optimistic, not only China, the global economy is in the doldrums, although China's GDP is still growing, but the growth rate has declined for five years, and it is likely to continue declining in next few years. After years of rapid economic growth, the current slow growth is a normal phenomenon. Peking University scholars believe that China is undergoing historic economic restructuring. In this tough economy condition, businesses and individuals need to do the pre-judgment for the future development. In addition, the continuous depreciation of the RMB has a great impact on the domestic economy.

What are the main reasons for the decline of China's current economy? Professor of Economics Hai Wen said that the first reason is a long-term trend. The growth of a country's economic cannot always keep 10% of high growth. On the other hand, the second reason is now China is now facing macroeconomic cycle. This recession is still a continuation of the 2009 recession. It can be seen from the tungsten market a few months ago that the price is fluctuating and most buyers have been kept wait-and-see attitude for a long time, resulting in the overall trading volume of whole tungsten market (tungsten heater) is in decline. While China's GDP growth rate has slowed compared to previous years, China's economy still has a great potential for development. Because China is in the take-off stage of economic, and the development potential is from the four areas, including services, urbanization, technology, innovation and manufacturing industry and the new developed space to brought by " The Belt and Road Initiative ". With the development of science and technology, it is believed that there will be more room for the development of China's economy in the future. Therefore, the tungsten market will be better soon.
