QSAM's machinable boron nitride ceramics
High purity boron nitride could withstand higher temperature in vacuum than lower purity and composite boron nitride products. However, the composite materials generally enhanced mechanical properties such as bending strength, and the high temperature performance in air. Due to the low wetability with metals, boron nitride rod is an ideal material for metal melting works, especially for high purity material metal in vacuum.
QS Advanced Materials is a leading supplier of boron nitride machinable ceramics in the market. Our products are available in the largest sizes, with dimensions up to 16" x 16" x 8". In addition to the conventional BN99 pure boron nitride ceramics, we also offer high purity TPBN with a purity of 99.9%, and enhanced boron nitride ceramic with improved hardness and wear resistance (ALNBN, ZCBN,etc.). All of our BN products are machinable, and we can supply raw materials for your workshop as well as finished products based on customer drawings. Choose QS Advanced Materials for the highest quality boron nitride machinable ceramics on the market.

About other boron nitride brands
Hexagonal Boron Nitride (h-BN) has a hardness of about 4, making it a machinable material. HBN/HBR originally referred to product codes for other manufacturers and denoted boric oxide or calcium-enhanced boron nitride materials, respectively. QSAM also provides calcium borate-enhanced boron nitride rods with similar performance to HBN and HBR. While calcium (or zirconium) enhanced HBR (or ZSBN) is the most common composite boron nitride material, we also produce a range of other composite boron nitrides, such as AlN-BN and SiC-BN.
