Gold-based solder

Gold-based solder is based on gold. The main alloy components are nickel, copper, palladium, zinc, copper, germanium, tin, etc. Compared with silver solder, it has strong corrosion resistance, low vapor pressure and good performance. Features such as fluidity and wettability. It can braze copper, nickel-substitutable alloys and stainless steel, etc. It is especially suitable for the brazing of important parts such as electric container parts and aero-engines. It has a wide range of applications in the aviation industry and the electronics industry.
