Tin Metal | Sn Metal

Tin, a silvery-white metal, is a member of group 14 in the periodic table. It is commonly used in a wide range of applications due to its unique properties, including corrosion resistance and ease of alloying with other metals. Tin (Sn) is soft and flexible, with a melting point of 231.89℃ and a boiling point of 2260℃. There are three isotypes: white tin, gray tin, and brittle tin. When you put it into a coal ball stove, it melts into a mercury liquid. It is stable and not easily oxidized by oxygen at room temperature, so it often maintains a silver luster. Tin is non-toxic and is often plated in the inner wall of a copper pot to prevent copper and warm water from producing toxic aerugenerine (alkali copper carbonate).

Tin Metal Specifications

Tin Metal Application

High-purity and ultra-high-purity Tin (Sn) materials are crucial components for the research, development, and production of advanced technologies that require optimum properties, performance, and quality.

• Used in soldering applications due to its low melting point and ability to form strong bonds between metal surfaces.
• Used to coat steel or iron to produce tinplate, which is used for packaging food and beverages.
• Used to create alloys with desirable properties.
• Used in electrical applications, such as in the production of tin-plated copper wires, connectors, and circuit boards.
• Used in the production of thin-film solar cells, which are an alternative to traditional silicon-based solar cells.

Tin Alloy Application

• Bell metal, is made by combining tin with copper. This alloy is prized for its use in making bells and other musical instruments due to its acoustic properties.
• Tin-lead alloys, often used in soldering materials, are also widely used in the electronics industry. In these applications, small amounts of tin are typically combined with lead to improve the solder’s melting point and workability.

Oxidation States of Tin

Tin exhibits two main oxidation states: +2 and +4.

• +2 Oxidation State (Stannous): The stannous (Sn²⁺) state, also called stannous chloride (SnCl₂), represents the +2 oxidation state.
• +4 Oxidation State (Stannic): The stannic (Sn⁴⁺) state, found in compounds like tin oxide (SnO₂), represents the +4 oxidation state.

These oxidation states enable tin to form a variety of compounds, including:

• Salts
• Oxides
• Alloys

Aside from its alloys, tin oxide plays a crucial role in various industrial applications, such as:

• Coating for glass to enhance durability
• Ceramics for improved resistance to corrosion

Tin Metal Packing

Tin (Sn) is carefully packaged in carton boxes with foam protection to minimize damage during storage and transportation and to preserve the quality of our products in their original condition. The vacuum packing is 1kg/bag, 25kg/barrel, or based on specific requirements.
