The alloy composition of the tin wire is divided into tin-lead, tin-copper, etc., which are made by adding flux and evenly pouring into the middle part of the tin alloy.
Silver wire is a chemical substance with a molecular formula of Ag. It is a white shiny metal with a face-centered cubic structure. It is an excellent conductor of heat and electricity; it does not react with water and oxygen in the atmosphere, and it does not react with ozone sulfide It turns black with sulfur; it is inert to most acids and can quickly dissolve in dilute nitric acid and hot concentrated sulfuric acid,  its surface and dissolve in molten alkali peroxide in air or in the presence of oxygen. and alkali cyanide; most silver salts are light sensitive and insoluble in many acids.
From the above concepts of tin wire and silver wire, we can roughly know that tin wire and silver wire are actually two different types of substances. The differences are mainly manifested in the following aspects:
1. The color is different: the tin wire is a kind of bluish white luster, and the color of lead-free tin wire will be yellow. The silver color is white and more pure white.
2. The melting point is different: the melting point of tin is 183-227°C, which is very low compared to silver wire. The melting point of silver wire is 960°C (lit.), which is much higher than that of tin wire.
3. Different hardness: Tin wire has low hardness, and it is easy to break after being folded several times by hand. Compared with tin wire, silver wire has a higher hardness and is not easy to break.
4. Different uses: Tin wire is mainly used for tinning solder joints of electronic products, post-soldering processing, etc.; while silver is a very small trace element in the process of manufacturing tin wire, and the main use of silver is for gifts and accessories , handicrafts, electronics industry, etc.
