Analysis of application prospects of nickel, copper and cobalt powder for diamond tools

The metal powder for diamond tools mainly includes nickel powder, copper powder, cobalt powder and alloy powder. With the continuous development of the world economy and science and technology, its market demand has increased dramatically, and its application prospects in new high-tech industries are broader.

(1) Prospects for the development of nickel powder market
Nickel powder has a wide range of applications due to its special properties. Nickel powder in the diamond tool industry is also very promising as a catalyst. At present, the amount of nickel used in the catalyst industry is 5,000 tons. The annual consumption of nickel powder in other fields is also increasing. From the perspective of the development of the domestic market, diamond thin-walled drill bits, cutting sheets, oil and natural gas, and other diamond drill bits for cement and natural gas drills are mostly made of nickel powder; metal materials processing, automobiles, motorcycles. Most of the tools used for mechanical grinding and processing use diamond abrasives, and most of the carcass materials are nickel powder. With the rapid development of the diamond tool industry, electrical alloy industry, powder metallurgy machinery parts and other industries, the demand for nickel powder has shown a rapid development momentum. China's existing nickel powder production enterprises only 7 to 8 (including carbonyl nickel powder, electrolytic nickel powder and reduced nickel powder), the production capacity of about 1,000 tons, the production capacity is far from meeting the needs of the domestic market. From the perspective of the development of foreign markets, according to the data of the international nickel market in recent years, the consumption of nickel-based powder is about 130,000 to 150,000 tons/year, accounting for almost 17% of the world's average nickel consumption. Its price has been stable. Between 12,000 and 13,000 US dollars per ton. It can be seen that the demand for nickel powder in the international market is very considerable.

(2) Prospects for the development of cobalt powder market
China's cemented carbide and diamond tools account for the world's largest output, and the consumption of cobalt is relatively large, about 2,000 tons. In recent years, due to the rapid development of the international and domestic battery industry, the amount of cobalt powder has risen sharply. From the perspective of domestic market demand, there are mainly 10 enterprises that use cobalt and cobalt to produce cobalt salt and cobalt powder in China. The total production capacity is 1,850 tons/year, which has become one of the world's major cobalt consumers. The consumption accounts for about 10% of the total cobalt. . At present, the domestic demand for cobalt is about 3,000 tons per year. In cemented carbide, cobalt powder is mainly used as binder, and its average content is about 10%. The consumption has reached 800 tons/year in China, accounting for 33% of the total cobalt consumption in the country, and is nearly 5.4% per year. The amplitude is increasing. From the perspective of foreign market demand, since the 1990s, the world's cobalt consumption has been on an upward trend, with an average annual growth rate of 2.6%. In 1998 alone, the world's cobalt consumption reached 29,500 tons. According to relevant information, the consumption of cobalt powder in the world will increase by about 8,000 to 10,000 tons in the next few years, and the consumption will rise sharply.

(3) Prospects for the development of copper powder market
Copper powder is an important powder material after iron powder. Copper and its alloy powder metallurgy products are widely used in friction materials and oil-bearing bearings because of their good electrical conductivity, thermal conductivity, corrosion resistance, surface finish and non-magnetic properties. , electrical contact materials, conductive materials, diamond products, filters and mechanical parts. Among them, electrolytic copper powder is more widely used in diamond tools, powder metallurgy, friction materials, electric carbon products, electrical alloys, metal coatings and pigments, electronic pastes, conductive rubber and other products with its excellent physical properties and chemical purity. In recent years, the amount of copper powder has increased at a rate of more than 10% per year. Taking the automobile industry as an example, the amount of copper powder used has exceeded 10,000 tons. If the electronics, electrical appliances and other industries are taken into consideration, the potential market is broader. From the perspective of the development of the domestic market, in China, copper powder is widely used in iron-based copper-based powder metallurgy parts, of which copper-based powder metallurgy parts are the largest. The average copper content in powder metallurgy parts is calculated as 5%. By 2005, the copper powder consumption will reach 5,000 tons/year. In the diamond tool industry, in recent years, due to increased competition from diamond tools, carcass materials have been tilted toward inexpensive iron-based, copper-based and bronze-based materials, particularly export tools and home interior finishing tools. The relevant data shows that there are more than 100 enterprises with annual usage of copper powder and copper-based powder for diamond tools of more than 20 tons. Therefore, the annual use of copper powder in the diamond tool industry is estimated to be between 2000 and 3000 tons. In the case of electrical alloys, the amount of electrolytic copper powder is about 200 tons. According to the demand of foreign markets, according to the statistics of the Nonferrous Metals Association, the annual demand for copper and copper alloy powders in the world is more than 100,000 tons, of which annual output in North America accounts for about half of the total demand. In 2002, China's copper powder imports were 23,274 tons, an increase of 22.78% over the previous year. At the same time, copper powder in other Southeast Asian countries is mainly used for material processing, and the demand is expanding year by year, but none of them have copper powder production enterprises.
