Copper-based special alloy electrical contact material is an innovative product. This material can be used to manufacture a variety of electrical contact elements, such as electrical contact rivets, copper clad silver strips, silver copper electrical contact point, etc. The welding resistance of electrical contact materials can be greatly improved by adding a small amount of diamond and other trace elements to the copper matrix and compounding it with the copper matrix. This can improve the safety of electrical contact materials and greatly reduce the possibility of fire. At the same time, diamond has the characteristics of high hardness and high wear resistance, which improves the mechanical wear resistance and arc ablation resistance of the material, so that the material has high arc extinguishing ability. In addition, other trace elements in copper matrix can also improve the oxidation resistance of materials at room temperature and high temperature.
Compared with silver-based electrical contact materials, the cost of copper-based special alloy electrical contact materials is lower, and its price is about one third of that of the former. Therefore, copper-based special alloy electrical contact materials have strong market competitiveness.
At present, the demand for copper-based special alloy electrical contact materials is higher and higher in the market because of its good performance and low price. However, because this material is an alternative to the core components of household appliances, its promotion still needs the testing and running in of various household appliance manufacturers. Because of this, its marketing process is relatively slow.
On the other hand, this material is the main material for making cold forming contact elements, which are the core components of various electrical appliances. Therefore, this material is a consumable in great demand. With the development of electric power and the increase of electrical appliances all over the world, the demand for this material is also increasing. Take China as an example, China's annual increased power consumption is about 40 million kilowatts. For every 10000 kW of power consumed, 40000 electrical appliances and 0.5 tons of electrical contact materials are required. By 2020, China's home appliance sales will reach 100 billion yuan. This shows that the market has a huge demand for copper-based special alloy electrical contact materials.
At present, the international custom electrical contact component market shows a rapid growth trend. Asia Pacific regions such as China and South Korea have become the regions with the fastest growth in the professional contact component market. The United States, Japan and Germany are still the countries with the largest market distribution of electrical contact components. Copper-based special alloy electrical contact materials are conducive to changing the market pattern of all purpose electrical contact components. In countries with developed power industry, there is also a great demand for industrial electrical contact components. The emergence of copper based special alloy electrical contact materials will bring huge market space. It is estimated that the annual export volume of the electrical contact material market in Europe and Asia is about 1875 tons.
Therefore, copper-based special alloy electrical contact materials will bring great changes to the electrical contact material market.
