DAIKOWT AlSi5

AlSi alloys are widely used due to their excellent aesthetic characteristics and surface smoothness. They exhibit low sensitivity to crack formation during welding, especially when used with 6000 series base alloys. Due to the silicon content, these alloys have a lower melting point and increased fluidity compared to 5000 series filler alloys, offering an improved weld appearance. However, the weld metal is not suitable for decorative anodizing purposes. The main applications of these alloys are found in general construction and the automotive industry, thanks to their good mechanical properties and excellent corrosion resistance. Their low melting point ensures minimal distortion in the base metal. A higher silicon content improves fluidity while reducing the risk of hot cracking. This type of alloy is generally used for brazing aluminum sheets, extrusions, and castings, as well as in applications involving high and prolonged temperatures.
