Metal with Low Melting Point

There are several metals with low melting points, but two notable examples are lead (Pb) and tin (Sn). These metals have relatively low melting points compared to other metals, making them useful for a variety of applications.

Lead (Pb)
- Melting Point: 327.5°C (621.5°F)
- Symbol: Pb
- Atomic Number: 82

Tin (Sn)
- Melting Point: 231.93°C (449.47°F)
- Symbol: Sn
- Atomic Number: 50

Properties of Lead (Pb)
- Soft and malleable: Lead is a soft metal that can be easily shaped or bent without breaking. This characteristic makes it useful for applications such as piping, roofing, and soldering.
- Low melting point: Lead has a relatively low melting point of 327.5°C, which means it can be melted easily using common heat sources like a gas flame. This property makes lead a suitable material for casting, alloying, and soldering purposes.
- Ductile: Lead is highly ductile, meaning it can be stretched into thin wires without breaking. This property makes it useful for electrical wiring and cable sheathing applications.
- Corrosion-resistant: Lead has excellent corrosion resistance, making it suitable for use in environments with high humidity or exposure to chemicals. This property makes it an ideal choice for lining tanks, pipes, and containers that transport corrosive substances.
- High density: Lead is a dense metal, which provides it with unique properties such as sound dampening and radiation shielding. It is commonly used in the construction of soundproof rooms, radiation protection equipment, and weights for various applications.

Properties of Tin (Sn)
- Malleable: Tin is a malleable metal that can be easily shaped or bent without breaking. This property makes it suitable for applications such as tin cans, soldering, and plating.
- Low melting point: Tin has a relatively low melting point of 231.93°C, which means it can be melted easily using common heat sources like a gas flame. This property makes it ideal for soldering and casting purposes.
- Ductile: Tin is highly ductile, meaning it can be stretched into thin wires without breaking. This characteristic makes it useful for electrical wiring and soldering applications.
- Corrosion-resistant: Tin is highly resistant to corrosion, making it suitable for use in environments with high humidity or exposure to chemicals. It is commonly used in the production of food cans, tin roofs, and protective coatings.
- Alloying agent: Tin is often used as an alloying agent in combination with other metals to improve their properties. For example, tin is used in the production of bronze (copper-tin alloy) and solder (tin-lead alloy), which have enhanced strength and durability.

Conclusion
Lead and tin are two metals with low melting points, making them versatile materials for various applications. Their unique properties, such as softness, low melting points, ductility, corrosion resistance, and alloying capabilities, make them suitable for a wide range of industries, from construction and electrical to automotive and manufacturing.

Gallium and Caesium are the two metals which have low melting point.
