SMM10 March 27: at the 2020 China International Silver Industry chain Summit Forum and China Silver Market Application Symposium, Song Zhenyang, Technical Director of Fuda Alloy New Materials Co., Ltd., brought you a speech on "the development status and future trend of silver-based electrical contact materials".
General situation of Electrical contact Materials Industry
Song Zhenyang first introduced low-voltage electrical appliances, which manually or automatically turn on and off the circuit according to external signals and requirements, so as to realize the switching, control, protection, detection, transformation and adjustment of circuits or non-electrical objects. According to its working voltage, the control appliances can be divided into two categories: high voltage control appliances and low voltage control appliances with AC 1200V and DC 1500V as the boundary.
Generally speaking, low-voltage electrical appliances can be divided into two categories: distribution appliances and control appliances, which are the basic components of complete sets of electrical equipment.
Material composition and technology
Application field
If there is electricity, there is electrical contact, so the application field of electrical contact materials is very broad. Commonly used for life switch, industrial control, power distribution protection. In terms of specific environment, it can be used for communication equipment, building power distribution, household appliances, motor control, 5G new base station, railway signal system, automatic control device, automobile industry and so on.
Market capacity
In 2019, the global market for electrical contact materials reached US $4.1 billion and is expected to reach US $5.9 billion in 2025, with an annual compound growth rate of (CAGR CAGR) of 6.34%. During the 13th five-year Plan period, the overall output value of the electrical alloy industry has increased year by year, but the overall profit level of the industry is not high, and the average sales profit margin per enterprise is only about 2-3%.
The use of silver
In terms of the amount of silver used in the industry, in recent years, the total production of low-voltage electrical contact materials has been increasing in 2019. The amount of silver used in the industry is more than 2000 tons, and the output of key products such as silver tin oxide, fine-grained nickel-carbon tungsten and other key products have increased slightly or remained the same.
The situation faced by the Development of Electrical Alloy Industry during the 14th five-year Plan
Song Zhenyang believes that the development of the electrical alloy industry during the 14th five-year Plan is mainly faced with the following situations:
1. The competition of global electric contact industry presents a new pattern.
The physical output of electric contacts in China has accounted for more than 40% of the world's total output, and the product line extends from the middle and low end to the high end. Foreign-funded enterprises are gradually at a disadvantage in the competition, constantly closing factories or restructuring their business. During the 14th five-year Plan period, the pattern of the global electric contact industry will be further adjusted, the competitive pressure faced by Chinese enterprises will increase, and the tasks of structural adjustment and industrial upgrading will be urgent and arduous.
2. The space contained in the implementation of the new national strategy.
The implementation of national strategies such as "Belt and Road Initiative", "new infrastructure" and free trade zone will vigorously promote the construction of transportation infrastructure and energy infrastructure, implement intelligent manufacturing projects, and develop intelligent equipment and intelligent products. At the same time, the steady growth of home appliances, office equipment, new energy vehicles and other industries, and the continuous expansion of electrical contact materials in aviation, military and other new fields will provide a new driving force for the sustainable development of the whole electrical contact materials industry.
3. New requirements for high-quality economic development
With the rapid development of China's economy, users' demand for high-quality products is getting stronger and stronger, which forces domestic enterprises to speed up their strategic adjustment, positioning transformation, technological innovation and ability enhancement. with high-end, high-quality products to join the competition in the domestic and foreign high-end product market.
4. the integration of manufacturing and information technology leads to new changes.
The "2025-year Plan" and "Internet +" made in China have been promoted in an all-round way, and the in-depth application of information technology in product design, manufacturing, equipment management, process quality control, etc., will promote the transformation of the production mode to flexibility, intelligence and refinement. Change from traditional manufacturing to service-oriented manufacturing. The deep integration of contact manufacturing and information technology not only provides a broad space for innovation and development, but also challenges the traditional mode of production and management.
