Machinable Aluminum Nitride BAN

BAN combines Aluminum Nitride with Boron Nitride, a hybrid machinable Aluminum Nitride ceramic with excellent thermal conductivity, high strength, and resistance to thermal shock. Innovacera provides BAN, and it has very similar properties to SHAPAL material. SHAPAL is a trademark of Tokuyama Corporation.


These ceramics are used in various industries, including electronics, semiconductor manufacturing, aerospace, automotive and medical. BAN ceramics have properties that make them suitable for applications such as heat sinks, heater substrates, semiconductor processing components, and optical equipment.


Material Advantages:

  • High mechanical strength.
  • High thermal conductivity.
  • Low thermal expansion.
  • Low dielectric loss.
  • Excellent electrical insulation.
  • High corrosion resistance–non-wetted by molten metals.
  • Excellent Machinabilit–BAN can be machined to high-precision complex shapes.
  • It has excellent sealing ability to vacuum and hasn’t given off much gas.
  • High-frequency wave properties, allow visible infra-red light to pass through easily.
