1.The Introduction of 4045 brazing aluminum sheet foil coil strip
4045 brazing aluminum sheet foil coil strip belong to the A-Si series near eutectic alloy, which cannot be heat-treated and strengthened aluminum alloy. It has excellent welding performance, casting performance, good wear resistance, high penetration, high specific strength, and low expansion coefficient etc advantages. Because of its low melting point, narrow solidification range, and good fluidity, it is conducive to the shrinkage and cracks of the weld during solidification, and it is often used as an aluminum alloy brazing material. But its thermal processing performance is relatively poor.
