Carbide-Supported BZN® Compacts

Hyperion PCD blanks

Hyperion Materials & Technologies manufactures a complete line of high quality polycrystalline cubic boron nitride (PCBN) products for machining ferrous materials. BZN® Compacts consist of the finest Borazon® CBN particles sintered and integrally bonded to a cemented tungsten carbide substrate or produced as solid PCBN products.

The products are designed to deliver maximum productivity in specific applications. BZN® Compacts excel on cast irons, hardened steel, powdered metal, hard facing alloys, and superalloys. They are commonly used in the automotive, aerospace, heavy machining, die and mold, and medical industries.
