Aluminum automated brazing filler metals

R&D background In recent years, as copper becoming a scarce strategic resource, the price of electrolysis copper increased so high that the consumers in the entire materials industry are choosing aluminum instead of copper; which is carried forward and processed smoothly and quickly through materials scientist and a group of enterprises. And in some specific field, “aluminum replaces copper” has implemented successfully. While, there also exist problem in aluminum brazing industry.

Disadvantages of traditional aluminum brazing 1. The melt point of aluminum soldering materials is 580 degree or so, which is close to the parent materials’ of 630 degree. With high defective rate of welding, it requires using experienced and skilled aluminum technician in real brazing production, caused high cost as well.

2. Choosing corrosive flux is easy to cause solder corroded once it entered inside of tube.

3. for the flux and solder are separately, there would be certain difficult to carry out automatic brazing. And directly restrict the implementation of the process of mass automation.

Filled the gap domestically Therefore, in recent years, specialists working in technical research of brazing domestic and overseas are seeking for solution of non-corrosive automatic brazing aluminum solder; which was developed and applied successfully in one of foreign enterprises, and absolutely monopoly domestically, but clogged up the promotion of new technology for expensive price. To breakthrough the technical domination overseas, striving for high-end materials nationalization, For many years constant efforts, R&D team of Jinghang brazing technology, overcame this problem ultimately, developed and researched the non-corrosive automatic brazing aluminum solder, filled the gap in domestic market.

Features: automatic brazing solder, without smearing corrosive weld paste and flux during welding. Brazing directly, cut off smearing brazing flux process and improved product efficiency. Without cleaning after welding for non-corrosion material on surface.
