This paper discusses the processing methods of brazed plate and building panel by aluminum plate manufacturers
1. Heat exchanger brazing plate (coating)
真空釬焊散熱器用的W31C合金是由鋁板制造商開發的。該合金是由1-m n-sn合金作為散熱器的核心材料和4005合金(ai-9.8% si-0.6% Mg)作為兩側的熔覆層組成。傳統上，鋁鋅合金7072是散熱器的核心材料。它作為功能陽極，防止上部管道的腐蝕。但是，這種合金中的鋅會發絲，所以不適合制作真空散熱器。在W31C合金中，錫代替了傳統散熱器和鐵芯中的鋅。該合金已成功開發并廣泛應用于管道材料的陽極真空釬焊散熱器的生產中。
W31c alloy for vacuum brazing radiator is developed by aluminum plate manufacturer. The alloy is composed of 1-m n-sn alloy as the core material of radiator and 4005 alloy (ai-9.8% si-0.6% Mg) as the cladding layer on both sides. Traditionally, aluminum zinc alloy 7072 is the core material of radiator. It serves as a functional anode to prevent the corrosion of the upper pipe. However, the zinc in this alloy can hair, so it is not suitable for making vacuum radiator. In w31c alloy, tin replaces zinc in traditional radiator and iron core. The alloy has been successfully developed and widely used in the production of anode vacuum brazing radiator for pipeline materials.
The thickness of these brazed plates is 0.13x0.16mm. The grain size of the plate is limited to more than 100 microns to prevent excessive diffusion of silicon from the cladding to the core during brazing.
2. Make colored or anodized panels for building panels
Industrial pure aluminum 1050, 1100 and Al Mg 5005 are widely used because of their excellent glossiness after anodizing and coloring with 6063 extruded profiles. It is a common defect that there are stripes on the surface after anodizing. Because these defects correspond to inhomogeneous metallographic defects in ingots, such as polar dendrite or suspended crystal, these defects can be prevented by controlling the casting process.
