Brazing directly, cut off smearing brazing flux process and
improved product efficiency.

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.
