Tin (Sn, symbol: stannum) is an almost silver-white metallic element, malleable, somewhat ductile and highly crystalline. Its atomic number is 50, and it is abundant in the Earth’s crust, chiefly in cassiterite which is an oxide mineral.
Typical applications include self-lubricating bearings, friction materials, chemical formulations, metal-bonded abrasive wheels and cutting tools, and metallic bonding. It is also used in cosmetics and jewelry.
sn powder has excellent physical properties and a wide range of uses in additive manufacturing, including ceramics, electronics, medical devices and industrial coatings. It can be sprayed or atomized to produce a range of particle shapes and sizes.
Nano-tin has a high surface activity, a large specific surface area, good dispersion characteristics and a uniform particle size. It can be mixed with lubricating oil and used to reduce friction, wear and corrosion in engine systems.
sn powder can be applied to metal and non-metal conductive coating under anaerobic conditions and low melting temperature. It can significantly reduce the sintering temperature of powder metallurgy products and high temperature ceramic products, while it can form a self-lubricating and self-repairing membrane on the surface of friction pairs during the friction process, remarkably reducing anti-friction and anti-wear performance of friction pairs.
