  • Our company has a series of copper brazing pastes, such as Copper brazing paste, Bronze brazing paste, Brass brazing paste and Copper Phosphorus brazing paste and so on. All the product can be provided by two major categories of water-based paste and oil-based paste and may be adjusted according to requirements.

    The welding powder, flux and paste fluid for the brazing paste are produced by ourselves, so we can perform quality control strictly for every link of paste production. Because of our unique pulverizing process, the oxygen content of welding powder with good sphericity can be controlled under 600 ppm.

    To customers' needs, the paste fluid with major categories of water-based copper brazing paste and oil-based copper brazing paste, can be adjusted on viscosity, volatility, adhesive strength with substrate, etc.


    Product Feature:

    1、Brazing temperature range: 700℃-1100℃.

    2、Welding powder by gas atomization with high quality can certify for good welding with stable quality and high strength.

    3、Copper brazing paste with good demouldability for steel network printing, glue needle point and convenient automatic production.

    4、Copper brazing paste with mild smell and non-toxic side effects to the human body.
