At present, a number of provinces, municipalities and districts have held a standing committee policy, requiring leaders to transfer to domestically-owned brand cars. Among them, Gansu, Ningxia, Xinjiang, Hunan, Anhui and other provincial (district) committees have passed relevant regulations on improving work style, and demanded to gradually transfer to self-owned brands without causing waste. It is a gray-black metal with metallic luster (body-centered cubic crystal). Melting point 3400 ℃. Boiling point 5555℃. The hardness of tungsten is the hardest among metals. The hardness of the sintered Tungsten Rod is 200~250, and the tungsten rod passed through the rotary hammer is 350~400. Soluble in mixed acid of nitric acid and hydrofluoric acid. Melt with a mixture of sodium hydroxide and sodium carbonate. Slightly soluble in nitric acid, sulfuric acid, aqua regia; insoluble in water, hydrofluoric acid, potassium hydroxide. Tungsten is available in two variants, a and B. At standard temperature and atmospheric pressure, type a is a stable body-centered cubic structure. Type B tungsten can only appear in the presence of oxygen. It is stable below 630 °C, and is converted into a-tungsten above 630 °C, and this process is irreversible. Tungsten is mostly used in the production of cemented carbide and ferrotungsten. Tungsten and chromium, molybdenum and cobalt form heat-resistant and wear-resistant alloys for making tools, metal surface hardening materials, gas turbine blades and combustion tubes, etc. Tungsten and tantalum, niobium, molybdenum, etc. form refractory alloys. Tungsten copper and tungsten silver alloys are used as electrical contact materials. High-density tungsten-nickel-copper alloy is used as a radiation shield. Metal tungsten wires, rods, sheets, etc. are used to make parts of light bulbs, electronic tubes and electrodes for arc welding. Tungsten powder can be sintered into filters of various porosity. FW-1 is used as raw material for large slab and tungsten-rhenium galvanic couple. FW-2 is used for contact alloy, high specific gravity shielding material. FWP-1 is used for plasma sprayed materials.

"This news is undoubtedly good for independent brands. I hope more cities will respond to the call and expand the scope of procurement." The marketing department of Brilliance Auto Sales Company admitted to the newspaper yesterday that it was frank.
Since last year, several favorable support policies for self-owned brands have been introduced, but some policies have quickly disappeared. For example, on February 24, 2012, the "2012 Catalogue of Official Vehicles for Official Use of Government and Government Officials (Consultation Draft)" (hereinafter referred to as "Catalogue") was introduced. The 412 models selected for the Catalogue are all self-owned brands, but since the publication of the consultation draft, no official documents have been produced.
Some insiders have bluntly said that the Catalogue has actually not progressed. There are also analysts in the industry who believe that bus purchases of self-owned brands have encountered resistance, and most of them come from foreign car companies.
But a few days ago, when reporters interviewed the relevant person of FAW-Volkswagen Audi sales company on the topic of official vehicles, it was learned that as a car company that was “smashed†in the official car market many years ago, Audi has now “retreated†in the official car market, “Now The number of government-only vehicles is very low, accounting for only about 10% of Audi's sales in China throughout the year," the source said.
However, the proportion of joint venture brands in the government official car market has not changed much. According to public data, before 2010, the amount of joint venture brand purchases accounted for nearly 90% of the procurement volume of official vehicles in China. From January to June 2011, the proportion of independent brands in government procurement was only 20%.
The industry believes that with the continuous improvement of domestic auto brands such as BAIC, GAC, Changan, Geely, Chery, Great Wall, BYD, etc., supplemented by policy assistance, independent brand auto companies will slowly open the official car market, “although overall The quantity is not large, but the market demonstration is not to be underestimated."
Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into wire, rod, tube, plate and other processed materials and certain shaped products. Tungsten powder mixed with other metal powders can be made into various tungsten alloys, such as tungsten-molybdenum alloy, tungsten-rhenium alloy, tungsten-copper alloy and high-density tungsten alloy. Another important application of tungsten powder is to make tungsten carbide powder, and then prepare cemented carbide tools, such as turning tools, milling cutters, drills and molds.
