    Product Description

    There are two kinds of boron powder in our company:
    Crystalline boron powder & amorphous boron powder.

    Compared with amorphous boron powder, crystalline boron powder is chemically more inert. Our crystalline boron powder has high purity, uniform particle size, strong oxidation resistance, good heat resistance and excellent compression resistance. At high temperature, boron powder can interact with oxygen, nitrogen, sulfur, halogen and carbon, and can also directly combine with many metals to form metal compounds, and can also react with organic compounds to form compounds in which boron is directly linked to carbon or compounds in which oxygen exists between boron and carbon.

    Crystalline boron powder is mainly used in alloy additives, synthetic diamond, wire drawing dies, other boron compounds raw materials or propellants, detonators, fluxes in the military industry, etc.
    1. 2N crystalline boron powder is generally used in boron-copper alloy, ferroboron alloy, boron-aluminum alloy, boron-nickel alloy, etc.
    2. 3N, 4N crystalline boron powder is mostly used in lithium-boron alloys.
    3. 3N, 4N crystalline boron powder can be made into amorphous boron powder

    Quality control system

    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.
