Stannum (Sn) powder, commonly known as tin powder, is a fine, metallic powder made from tin, a relatively soft, silvery-white metal with a low melting point (231.9°C). Tin is widely used in various industries for its corrosion resistance, soldering ability, and electrical properties. As a powder, it is used in a range of specialized applications that take advantage of these unique characteristics.

Application

1. Metal nanometer lubricating additives: add 0.1 ~ 0.5% nano tin powder to lubricating oil, grease, make the friction pair in the process of friction surface self-lubricating, self-healing membrane, significantly reduce the friction pair antiwear and antifriction performance.

2. Activated sintering additives: nano tin powder in the powder metallurgy slash powder metallurgy sintering temperature and high temperature ceramic products.

3. Metal and non-metallic conductive coating on the surface treatment: under anaerobic conditions, below the powder coating of the melting point temperature, the technology can be used in the production of microelectronic device.
