Grade AC6043 is a titanium diboride/boron nitride composite that is machinable and exhibits better oxidation resistance and improved strength compared to common furnacing materials such as graphite.
BNC 1 & 2
Grades BNC 1 & 2 offer excellent corrosion and wear resistance, have excellent thermal shock capability and low CTE, are non-wetting and are self lubricating.
AC6043 is used in replacement parts for areas of high oxidation where longer life and much lower erosion rates are needed such as vents, plates, stacks, crucibles, and capsules.
BNC 1 & 2 are useful in a broad range of metallurgical applications, including side dams, break rings, submerged nozzles, heat shields, spatter guards, stopper rods, slide gates, thermocouple wells and many other super refractory
AC6043, BNC1, and BNC2 can be machined using standard practices for hard ceramic materials, including diamond tooling with high cutting or grinding speeds and normal feed rates.
Momentive Performance Materials produces over 75 standard and custom grades of BN powders to meet a wide range of application requirements, and has over 40 years of expertise in the synthesis and refinement of boron nitride powders.
