As a kind of brazing filler metal, the aluminum-based alloy has a melting point of 450 ° C or higher, and the brazing temperature is usually selected to be higher than the liquidus temperature of the brazing material by 25 ° C to 60 ° C to ensure that the brazing filler metal can fill the gap. The bearing capacity of the brazed joint is related to the size of the joint surface. Therefore, the brazing is generally lap joint and kit to compensate for the lack of brazing strength.
 
The aluminum alloy brazing circle has high joint strength, good heat resistance and can work at high temperatures. The brazed aluminum circles produced by Mingtai mainly have 3 series and 4 series products, such as aluminum circles such as 3003, 3103, 4004, etc., which are commonly used in the field of oxygen equipment and radiators for the automotive industry. All kinds of brazed aluminum plates produced by Mingtai use German world-class advanced equipment such as Luke Spectrometer, Hitachi Scanning Electron Microscope and Energy Spectrometer, and American Thermoelectric Spectrometer to ensure the fine quality of the products. The products produced are beautiful and flat, bright in color, free from cracks on the surface, ensuring seamless welding during welding, good fluidity during welding, and no air bubbles.


 
Aluminum Brazing circle performance advantages:
A: High strength and excellent welding performance.
B: It has good heat and high temperature resistance and has certain corrosion resistance.
C: Excellent processing performance, small change in structure and mechanical properties, small deformation, easy to form.
D: The product is beautiful, the welding has no pores, cracks, welding tumors, etc., the surface of the welded joint is bright and the fillet is even.
