    1. Metal nano lubricating additive: Add 0.1~0.5% nano bismuth powder to the grease to form a self-lubricating and self-healing film on the surface of the friction pair during the friction process, which significantly improves the performance of the grease;

    2. Metallurgical additives: bismuth powder can be used as additives for cast iron, steel and aluminum alloys to improve the free cutting properties of alloys;

    3. Magnetic materials: bismuth has a small thermal neutron absorption cross section, low melting point and high boiling point, so it can be used as a heat transfer medium in nuclear reactors;

    4. Other applications:

    It is widely used in various bismuth alloy products, oil exploration perforating charges, low temperature solders, plastic fillers, electroplating wheels, grinding discs, sharpening knife, and the preparation of high-purity semiconductor materials and high-purity bismuth compounds.

    Quality control system

    quality control

    Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.

    Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
