Boron Nitride Machined Products

Hexagonal Boron Nitride, or h-BN, with hardness about 4, is a machinable material. As the sintering of this material is not quite easy, it requires about 1900C if it is hot pressed without any additive(usually boron oxide)High purity boron nitride material could withstand higher temperature in vacuum. Although we usually claim the maximum working temperature as 2500C, but some of our customer has records to use ou boron nitride product under about 3500C and its totally fine. Our boron nitride custompartswould have similar performance with other reputable brands, especially for high temperature applications.
HBN is originally a product code for Momentive Performance Materials and represents for the calcium enhanced boron nitride material. Amerigo Scientific also providies calcium borate enhanced boron nitride with similar performance compared with HBN. Although calcium (or zirconium) enhanced HBN (or ZSBN) are the most common composite boron nitride material, we also produce a series of other composite boron nitride, such as AlN-BN, SiC-BN.
