Analysis of demand status and development trend of cemented carbide industry

Hard alloy is a kind of alloy material made by powder metallurgy process of hard compounds of refractory metals and bonding metals. Carbide products are mainly tungsten carbide as the hard phase, cobalt as the bonding phase, by ball milling, spray granulation, pressing, sintering, with high hardness, strength, wear resistance and corrosion resistance, carbide known as. Industrial teeth; Mainly used in cutting tools, stamping tools, molds, mining and road construction machinery and other fields.

Cemented carbides can be classified into tungsten-cobalt alloy, tungsten-titanium-cobalt alloy, tungsten-titanium-tantalum (niobium) cobalt alloy, titanium carbide base alloy and coated alloy.

Cemented carbide can be divided into cutting tools, geological mining tools, molds, structural parts, wear-resistant parts, high pressure and high temperature resistant cavity and other uses.

Demand structure of cemented carbide products

Carbide is mainly used in cutting tools, mining tools, molds and high pressure and high temperature resistant cavity, among which the cutting tools and mining tools accounted for 33% and 25% of the application of carbide. In cutting tools, hard alloy is mainly used as tool materials, such as turning tool, milling cutter, planer, drill, boring tool, etc., used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel and difficult to process materials, etc., cutting processing mainly rely on machine tools to achieve. In terms of mining tools, hard alloy is mainly used as drilling tools, mining tools, drilling tools, and plays an important role in mining, oil exploitation, infrastructure construction and so on.

Demand for cemented carbide in cutting tools

The downstream application of cutting tools is very wide, at present, the domestic key customers have a greater demand for cutting tools products are: automobile industry enterprises; Ten major industrial groups in aviation, aerospace, weapons, shipping and nuclear industries; Machinery, railway locomotive, mold, textile, energy equipment, agricultural machinery, major complete equipment production and manufacturing enterprises. According to statistics, the world's cutting tool demand, general machinery and automotive manufacturing accounts for about 35% each, aerospace accounts for about 10%.

In recent years, the demand of Chinese cutting tools for cemented carbide is increasing year by year. In 2016, the demand for cemented carbide in cutting tools was about 9,686 tons, up 4.15 percent from the previous year. Demand is expected to break the 10,000 tons mark in 2017.

According to the national planning, by 2020 our country will become the manufacturing base for key sets of equipment and advanced scientific instruments for automobiles, large aircraft, ships, electronic components, large-scale integrated circuits, high-grade CNC machine tools and other components, all of which will greatly increase the demand for cutting tools. Forward estimates, to 2023, cutting tools for carbide demand will reach about 13600 tons.

Demand for cemented carbide in geological mining tools

In recent years, the rapid development of geology and mining industry in China has driven the demand for geological mining tools industry, and the demand for hard alloy for geological mining tools has also shown a growing trend. In 2016, the demand for hard alloy in geological mining tools industry was about 7512 tons, with a year-on-year growth of 4.39%. Demand is expected to grow to about 8,000 tons in 2017.

With the advance of coal mine integration, there will be a great deal of demand for mine tools. In terms of other minerals, the National Mineral Resources Plan (2016-2020) issued by the Ministry of Land and Resources clearly indicates that China is still in the middle stage of industrialization, and the growth rate of energy and resources demand is slowing down, but the total demand will still maintain a high level. It is estimated that by 2020, China's primary energy consumption will be about 5 billion tons of standard coal. 750 million tons of iron ore, 13.5 million tons of refined copper, 35 million tons of primary aluminum. Under the influence of the international mining market, the investment in domestic exploration tends to decline, but generally speaking, the demand for mineral resources in China is increasing, but the domestic mining is in a downward trend. The previous mode of low-yield and crude collection will be gradually replaced by the mode of high-yield mining, and the demand for high-quality mining tools will be greater. The Qianzhan Industrial Research Institute predicts that by 2023, the demand for cemented carbide for geological mining tools will reach about 10,000 tons.
