What is silver solder and what is hard solder?

Silver-copper-zinc environmental protection solder Silver solder can be combined with black and non-ferrous alloys. It is more advantageous when used in some vibration situations. Stay-Brite (tin-silver soft covered electrode): The performance is the same as above, and each set contains Stay-Brite covered electrode 14g and Stay-Clean low-temperature welding water 14g. It is especially suitable for small dose leak repair and welding. It is extremely convenient to carry and use. Stay-Brite E8 (No.8 tin-silver soft covered electrode): diameter 1.6mm, 454g/ coil, silver content 6%. Widely used in refrigeration and air conditioning industry. Compared with Stay-Brite, all components of Stay-Brite E8 have been strengthened, which is especially effective in the case of loose welding. The practical performance is better. Comparison between silver solder and Stay-Brite solder: Performance parameters: Sn and Ag in Stay-Brite Stay-Brite E8 composition (melting point) 221.1℃ 221.1℃ liquid phase temperature (water). 221.1℃ 221.1℃ tensile strength, copper sleeve pipe joint 9.84kg/mm2 10.54kg/mm2 shear strength 7.5kg/mm2 27.734kg/mm2 elongation 48% 48%. Solder paste (composed of Stay-Brite powder and flux) Flux: Stay-Clean flux can be used in any metal shape except aluminum alloy: 116, 3/32, 1/8 welding wires with equal diameters, containing rosin and flux, and welding ring packaging:1. Bridgit, 1/2 oz lead-free solder provides flux for Harris, which is a high-performance lead-free solder patent applied by Harris in response to the law prohibiting the use of lead-containing solder in drinking water system. This solder is also very suitable for loose and tight connections. The existence of nickel makes Bridgit's weld stronger than other lead-containing solders. Bridgit has outstanding ability in welding large welds, which can be easily welded. Bridgit solder paste is effective below 426.7℃, and it will not burn at welding temperature, which can reduce welding cavities and cracks caused by carbon deposition. This kind of solder has excellent effect in welding lead joints such as copper, brass, bronze and galvanized parts, and its operation form is the same as other solders. Cleaning Flux: For solders with liquid temperature below 37 1. 1℃, such as silver solder, Sn-Pb solder or Sn-Sb solder, use this flux to keep the solder paste clean: it can provide unparalleled cleaning work for copper, brass and steel, and can be used for any metal except lead alloy, magnesium alloy and tin alloy. Don't use it in electronic and electrical engineering. Harris flux I, keep it clean and flux can be used. All metals except magnesium alloy and tin alloy can be used with Stay-Brite solder, and can also be used with almost all other solders whose liquid temperature is lower than 37 1. 1℃, and cannot be used in electronic and electrical engineering. Clean aluminum alloy flux is used to weld aluminum alloy together with Alsolder500. Fourthly, Stay-Silv flux (white) is used with all silver-containing solders to weld all metals except aluminum alloy, magnesium alloy and tin alloy. The maximum effective temperature is 87 1℃. Fifth, Stay-Silv flux (black) is used together with silver solder or other solder with liquid temperature below 982℃. Large workpieces and places that need long-term heating. Suitable for all metals except aluminum, magnesium alloy and tin alloy. VI. Al-brass 1070 Flux Powder Flux (solder powder) is used together with1070 aluminum alloy solder.
