The development trend of the solder industry is improving. Hard solder and soft solder are the two major market segments.

Solder refers to the filler metal material used to form welds during brazing. According to different melting points, it can be divided into soft solder (solder with a melting point lower than 450°C) and hard solder (solder with a melting point higher than 450°C). Solder) two categories. Solder is an important material required in modern industry. It has connection functions, sealing functions, electrical conductivity functions, thermal conductivity functions, etc. It is mainly used in brazing connection scenarios between the same metal, dissimilar metals, metals and non-metals. The terminal application fields include Motors, air conditioners, refrigeration, electronics, automobiles, instruments, etc.

In terms of hard solder, according to different matrix elements, hard solder can be divided into aluminum-based solder, silver solder, copper-based solder, nickel-based solder, etc.; according to different brazing temperatures, hard solder can be divided into High-temperature brazing material with a welding temperature higher than 900°C and medium-temperature brazing material with a brazing temperature lower than 900°C. Among them, silver solder and copper-based solder are the two types of solder with high consumption in my country’s hard solder market.

Hard solder has the advantages of high connection strength, good high temperature resistance, strong corrosion resistance, and not easy to break. It is mainly used in the connection scenarios of high melting point metals such as steel, iron, and alloys. The terminal application fields include aviation, automobiles, machinery, etc. In 2022, my country’s hard solder output will be approximately 58,000 tons. The production companies mainly include Hangzhou Huaguang Welding New Materials, Jinhua Xinhe Welding Material Technology, Zhengzhou Machinery Research Institute, Changshu Huayin Solder, Hebei Yuguang Welding Industry, and Jinhua Jinzhong Welding Materials etc. There are a large number of domestic hard solder manufacturers, and they are concentrated in the Yangtze River Delta region. They have formed a relatively mature strategic emerging industry cluster, and the industry development trend is good.

In terms of solder, according to different base materials, solder can be divided into tin-based solder, lead-based solder, zinc-based solder, etc. Among them, lead-free solder is currently the mainstream product in the solder market, mainly including tin-based solder and tin-silver-copper lead-free solder. Representative products include soldering paste, BGA balls, etc. Soft solder has the advantages of high connection strength, good sealing, and will not damage the base material. It is widely used in connection scenarios with low melting point metals such as copper, aluminum, and magnesium. The terminal application areas are mainly electronic components, instrumentation, refrigeration equipment, etc.

According to the“2023-2028 Solder Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that my country’s solder market is currently growing at an average annual compound growth rate of more than 7%, and the industry has good development prospects. Domestic solder manufacturing companies mainly include Tongling Longfeng New Materials, Luoyang Junhao Electronic Materials, Zhejiang Tianli Jiutian Pipe Industry, Shenzhen Yuhang Metal New Materials, Zhejiang Yatong New Materials, etc.

Industry analysts said that solder is an important welding material used to connect metal parts. It plays an important role in industrial production and daily life, and has a broad market development space. Soft solder and hard solder are the two major segmented products in the solder market. Currently, their industries are showing a good development trend, which in turn drives the development of the domestic solder industry to continue to accelerate.
