Brass brazing alloy is a welding material with copper (Cu) as the basic component and an appropriate amount of zinc (Zn) added to form a brass body. In some specific brass brazing alloy formulas, it may also contain a small amount of other auxiliary elements, such as tin (Sn), lead (Pb), aluminum (Al), etc. The addition of these elements can further optimize the various properties of the alloy to better meet the needs of different brazing scenarios.
It can quickly fill the weld gap to ensure that the weld joint is dense and defect-free; at the same time, the alloy layer formed after welding has excellent tensile strength and corrosion resistance, and is suitable for dissimilar material connections of various metals such as copper, steel, and cast iron.
Efficient operation can be achieved by cooperating with conventional brazing process, and the workpiece surface is smooth after welding without complicated post-processing.
After brazing, it can ensure that the connected parts have a certain ability to withstand external forces, which is convenient for processing during the brazing operation and can ensure that the joints after welding have sufficient wear resistance.
The parts brazed together can maintain good performance under different environmental conditions and extend their service life.
The brass brazing rod is affordably priced. While ensuring welding quality, it effectively controls costs.
