(1) Silver-based solder, mainly based on silver-copper-zinc alloy-based alloy series, such as AgCuZn series, AgCuZnCd series, AgCuZnNi series; silver-nickel alloy, silver-copper alloy; alloy containing 90% silver and 10% copper Called currency silver, melting point 875. C; An alloy containing 80% silver and 20% copper is called fine industrial silver and has a melting point of 814. C; An alloy containing 40% or 60% silver and copper, zinc, and cadmium is called a silver flux, and its melting point is greater than 600. C. Mainly used for metal products with high connection strength requirements.
(2) Silver-based contact materials, mainly silver-copper alloys (AgCu3, AgCu7.5), silver-cadmium oxide alloys and silver-nickel alloys;
(3) Silver-based resistance material, silver manganese-tin alloy has moderate resistance coefficient, low temperature coefficient of resistance, small thermoelectric potential for copper, can be used as standard resistance and potentiometer winding materials; silver-molybdenum alloy, silver-tungsten alloy, silver-iron alloy, Silver-cadmium alloy;
(4) Silver-based electroplating materials, commonly used are silver-tin alloys AgSn3 ~ 5, AgPb0.4 ~ 0.7, AgPd3 ~ 5, etc .;
(5) Silver-based dental material, silver amalgam alloy, also known as amalgam, is a kind of alloy formed by reaction of mercury with mercury as solvent and silver copper tin zinc as alloy powder. It is an ideal dental implant material. Silver amalgam AgxHg, brittle solid with white unevenness. Its composition varies with the formation temperature; Ag13Hg (445.C), Ag11Hg (357.C), Ag4Hg (302.C), AgHg2 (less than 300.C).
