4043 aluminum sheet plate

Introduction of 4043 aluminum sheet plate
Application of welding alloy aluminum plate: 4000 series aluminum alloy (Al-Si series) is typically represented by 4043 and 4343 aluminum alloys, which are specially used as welding materials. 4043 aluminum sheet plate has the characteristics of low melting point, good fluidity, and good corrosion resistance, which is very beneficial to avoid welding cracks.
It is conducive to the shrinkage of the welding seam during solidification to reduce cracks, and is used as a composite brazing sheet coating.
