Application
Metal nano lubrication additive: add 0.1~0.5% nano tin powder to lubricating oil and grease, make the surface of friction pair form self-lubrication and self-repair film in the friction process, reduce the anti-wear and anti-friction performance of friction pair.
Activated sintering additive: nano tin powder can greatly reduce the sintering temperature of powder metallurgy products and high temperature ceramic products in powder metallurgy.
Conductive coating treatment of metal and non-metal surface: coating under the condition of no oxygen, below the melting point of the powder, this technology can be used in the production of micro-electronic devices.
