Specifications

Boron Nitride PBN Parts
1: high purity level
2: it is easily machined, such as cutting, boring and polishing
3:non-toxic

Performance PBN is a non-porous, opaque material with mechanical properties that are actually enhanced at high temperatures. Its crystalline structure- consisting of layers of hexagons composed of boron and nitrogen atoms stacked on top of each other in parallel planes-gives it good flexural strength, high compression strength and high fracture resistance.
