Alloy state: O, H14, H18
Can produce alloy thickness: 1.0-3.0mm Processing technology: hot rolling
As a kind of brazing filler metal, aluminum-based alloy has a melting point above 450°C, and the brazing temperature is usually selected to be 25°C-60°C higher than the liquidus temperature of the solder to ensure that the filler metal can fill the gap. The load-bearing capacity of brazing joints is related to the size of the joint connection surface. Therefore, brazing generally uses lap joints and kit inlays to make up for the lack of brazing strength.
The joint strength of the aluminum alloy brazing plate is high, the heat resistance is good, and it can work at high temperatures. The brazing aluminum plates produced by Henan Chalco mainly include 3 series and 4 series products and composite materials, such as aluminum plates such as 3003, 3103, 4004 3003 4004 aluminum brazing clad sheet roll, etc., which are commonly used in oxygen production equipment and radiators for the automotive industry. field. The products produced are beautiful and smooth, with bright colors and no cracks on the surface. Seamless welding can be ensured during welding, with good fluidity during welding and no bubbles.
4004 3003 4004 aluminum brazing clad sheet roll performance advantages:
A: High strength and excellent welding performance.
B: Good heat resistance and high temperature resistance, and a certain degree of corrosion resistance.
C: Excellent processing performance, small changes in structure and mechanical properties, small deformation, and easy molding.
D: The product is beautiful, there are no pores, cracks, weld bumps and other phenomena in the welding. The surface of the weld joint is bright and the fillet is even.
