Electrical contact materials are electrical appliances complete "connect - conduction - cut off current and carrier signal and transmission function, the electric contact performance is the key to influence the reliability of electrical and electronic engineering, in the field of low voltage apparatus has a" heart "of low voltage apparatus, is widely used in the relay, circuit breaker, contactor, sensors, industrial control, etc.
According to the new thought world industry research center released the 2018-2022 China electric contact material product market research and investment feasibility assessment report showed that the main producers of electrical contact materials in the world are mainly concentrated in Europe and Japan, because of its basic science is developing rapidly, science and technology talents reserve enough, in the preparation of new materials research and development capabilities, capacity, production automation, etc are one of the world's leading position, leading the development of the industry.At present, foreign companies producing and developing electrical contact materials mainly include DODUCO (Duck, Germany), Metalor (Mattel, Switzerland), Umicore (Meiko, Belgium), TANAKA (TANAKA, Japan), etc.
After years of development, China's electrical contact material industry has made considerable progress, with a complete range of basic products, which meet the demand of middle and low-end electrical products and some high-end products, and occupy a certain share in the international market.As far as the variety and performance of electric contact materials are concerned, all kinds of electric contact materials commonly used in the world can be produced domestically.
However, in terms of production scale, technological level and product quality, there is still a gap between China and developed countries in terms of contact materials. In addition to some advantages of individual enterprises, there are also many problems in the development of the whole industry.
First, there are many small-scale enterprises in the industry, whose technical personnel are insufficient and management level is relatively low. Meanwhile, they ignore r&d investment and replacement of production equipment, and have a low degree of automation. They adopt extensive mode of production and operation, and take price competition as their main means of competition.
Second, the research and development investment is insufficient, the preparation process updates slowly.Due to the increasingly fierce market competition at present, the pressure of enterprise survival has limited the development process of new materials, making Chinese electric contact material manufacturers lack competitiveness in the performance of high-end products (such as high performance silver-tin oxide contact materials, etc.).
