boron carbide nozzle made by b4c ceramic with the highest service life for wear resistant
boron carbide nozzle is used by 100% pure boron carbide materials, wear-resistant function is three times more
than tungsten steel, five times more than silicon carbide, super wear-resistant. The common chemical properties of
boron carbide ceramic are as follows:super hard and wear resistant, no reaction with acid and alkali, high
temperature and high pressure resistant, the density of boron carbide nozzles is more than 2.46g/cm3.
Microhardness is larger than 3500kgf/mm2, the bending strength is more than 400Mpa, the melting point of 2450 DEG
C. The boron carbide nozzle can replace the known sandblasting nozzle which is made of cemented carbide, silicon
carbide, silicon nitride, alumina, zirconium oxide and other materials.B4C nozzle made of B4C ceramic is the highest service
life for wear resistant with competitive price.
