Solder is an important raw material for connecting electronic components when soldering lines, including tin wire, tin ball, tin bar, etc. Applied to all kinds of electronic soldering, suitable for manual soldering, wave soldering, reflow soldering and other processes. The wire solder used in standard soldering operations is called rosin cored solder wire or wire. Flux is added to the solder. This flux is composed of rosin and a small amount of activator.
Tin is a metal element, an inorganic substance, and white tin in a common form is a low-melting metal with a silvery white luster. These two are completely different products and substances. Today, the editor of Double Chile Soldering Co., Ltd. collected and sorted out soldering tin The difference between tin and tin and relevant information are analyzed as follows:
1. The essence of solder and tin is different: tin is a simple metal; heating tin is odorless. Solder is made of alloys, and rosin and flux are added to solder during production, so the solder will have the smell of rosin when heated.

2. The physical properties of solder and tin are different: the common solders are environmentally friendly solder and tin-lead solder. Due to the different alloy composition ratios, the melting point is also different. The common solder wire and strips are made by melting ingots first, and then pressure processed into Lines or strips. Tin is a metal element with a silvery white luster and a low melting point. It is divalent or tetravalent in the compound and is not easily oxidized by oxygen at room temperature, so it often maintains a silvery luster. Metal tin is soft and easy to bend, with a silvery white metallic luster, a melting point of 231.89°C, a boiling point of 2260°C, and is non-toxic. Tin belongs to the fourth main group element in the periodic table of elements, with atomic number 50, atomic weight 118.71, and element symbol Sn. Tin is malleable at room temperature. Especially at 100°C, the ductility is very good, and it can be developed into extremely thin tin foil, which can be as thin as less than 0.04 mm. But the ductility is very poor, and it will break when it is pulled, and it cannot be pulled into filaments. At the same time, tin is a metal that is afraid of both cold and heat. At different temperatures, the form of tin is completely different.
3. The application of solder and tin is different: solder is widely used in electronics industry, home appliance manufacturing industry, automobile manufacturing industry, maintenance industry and daily life. Commonly used solder materials include tin-lead alloy solder, tin-copper alloy solder, antimony-added solder, cadmium-added solder, silver-added solder, and copper-added solder, which are indispensable solder materials in the manufacturing industry. Tin is non-toxic, not easy to oxidize and change color, and has good sterilization, purification, and fresh-keeping functions. In daily life, it is often used in food preservation, anti-corrosion film on the inner layer of cans, etc. As a trace element in the human body, tin plays a very important role in our health.
