Woods Metal, M.P. 70℉ - Introduction
Woods Metal(Woods Metal) is a low melting point alloy, mainly composed of bismuth (Bi), lead (Pb), antimony (Sb) and tin (Sn). Its chemical composition can be adapted to specific needs.
Woods Metal has the following main properties:
1. Low melting point: The melting point of Woods Metal is about 70°C to 100°C, so it can become a liquid state at a relatively low temperature.
2. Good fluidity: Woods Metal is very liquid when it is liquid, and can be easily filled or soaked into more complex shapes and small spaces.
3. Low surface tension: Woods Metal's low surface tension allows it to cover or fill small holes and cracks in contact with other materials.
4. Small expansion coefficient: The expansion coefficient of Woods Metal is small, so that it can be used to make high-precision molds and measuring instruments.
Key applications of Woods Metal include:
1. mold manufacturing: Because of its low melting point and good fluidity, Woods Metal is often used to make molds, especially for the manufacture of small parts and precision castings.
2. Fine abrasive particle curing: Due to its low melting point and low surface tension, Woods Metal can cure fine abrasive particles and provide support and protection during processing.
3. Smelting and welding: Woods Metal can be used as an auxiliary material for welding and smelting low melting point metals.
A common method of preparing Woods Metal is to heat bismuth, lead, antimony and tin in specific proportions to the melting point, mix well and then cool. Safety precautions such as wearing protective gloves and goggles to avoid direct contact with the molten alloy are required during preparation.
It should be noted that Woods Metal contains toxic elements such as lead and antimony, so safety measures should be paid attention to during use and handling. Avoid breathing its vapors or dust, be sure to operate in a well-ventilated area, and follow the relevant safety procedures. Make sure to store Woods Metal in a safe place when it is not needed to avoid harm to the human body and the environment.
