Thermal Filler (Alumina & hBN)

Product Information

Wide variety of Aluminum Oxide and Hexagonal Boron Nitride when thermal management is key!

Aluminum Oxide (Al2O3) filler been manufactured at Resonac for over 80 years and continues to make strides in this market.  Commonly referred to as alumina, Resonac supplies a wide variety of grades with unique and distinguishing features.

  • Roundish Alumina (AS Series): Manufactured in Yokohama, Japan, the AS Series of roundish alumina is a single grain corundum with fewer crystal edges.  Roundish Alumina is great for high filling into resins for thermal conductivity and low viscosity due to its large particle diameter and particle size distribution.
  • Spherical Alumina (CB Series): A single grained corundum that has an almost perfect spherical particle shape. Spherical Alumina lends itself extremely well for applications that require optimal fluidity such as potting compounds and greases.

Hexagonal Boron Nitride (hBN) can provide optimal thermal conductivity and is offered as both platelet and agglomerate types.  By utilizing Resonac’s proprietary technology, our agglomerate grade is particularly unique by providing exceptionally high particle hardness while maintaining a low level of impurities.

Abrasives and Super Abrasives

Product Information

Sinter Morundum (SM and SR), are a low porosity, high body strength, rod shaped sintered abrasives that are manufactured from bauxite (SM) and calcined alumina (SR), respectively.

SM and SR can be utilized in a number of abrasive wheel applications and provide a distinct advantage to other materials commonly used, such as Alumina Zirconia.  This is due to their lower density and higher thermal conductive capabilities.

Cubic Boron Nitride Abrasive Grain (cBN) was first synthesized in Japan by Resonac in 1978 and has continued to create cBN with new and unique properties since.

cBN has a hardness that is only second to diamond and is great for grinding/polishing steel since it does not chemically react to iron.  Resonac offers numerous grades with varying shape and crystal strength to meet different application requirements.

K-TIP is a sintered compact of cubic boron nitride (cBN) that utilizes Resonac’s proprietary ultra-high-pressure technology.  K-Tip is recommended for cutting hard ferrous alloys and other difficult to work materials.  This material is offered in two types, KT and KS Series and eight various grades for a wide range of machining materials.
