CAS 7440-42-8 25kgs/bag,20tons/20'container CAS 7440-42-8 is a black or dark brown powder. When it is oxidized in the air, it will prevent the internal boron from continuing to oxidize due to the formation of a boron trioxide film. It can react at normal temperature Amorphous Boron Powder is insoluble in water, powdered boron is soluble in boiling and most molten metals such as copper, iron, manganese, aluminum, and calcium. 1. Boron fiber has high strength (breaking strength at room temperature is 2744 ~ 3430MPa) and high modulus of elasticity (39200 ~ 411600MPa), which is an excellent reinforcing material. 2. Composite materials made of boron fiber with metal (aluminum, magnesium, titanium, etc.), various resins (epoxy resin, polyamide, etc.) and ceramics are excellent high-temperature structure materials. 3. Reinforcement ceramics made of titanium boride have excellent abrasive resistance and high toughness (up to 10 MPa�·m 1/2 or more), which are used to manufacture conductive parts for heating equipment and ignition devices. 4. Used as a deaerator in the metallurgical industry and an additive to improve the structure of metal grains. 5. Boron-cast iron is widely used in automobile, tractor, machine tool and other manufacturing industries.
It is Made with wear & heat resistant tungsten carbide. While the high speed drill touching the work piece and giving it downward force, the heat created by friction will melt the surface and the burrs will be made by the force on the surface. It require the drill has outstanding rigidity and hardness in the operation.
