BNP2 Machinable Aluminium Nitride
(Shapal M soft alternative)

BNP2 has all but identical properties to that of Shapal M and is a very cost effective alternative, it should be machined & treated in exactly the same way.

Grades of ceramic have been developed which can be machined but they are not suitable for all engineering applications due to their low flexural strength. BNP 2 has been developed as a direct eqvielent to Shapel M soft.

BNP 2 is a machinable ceramic which offers both high mechanical strength and thermal conductivity. The material has a composite sintered body of AlN and BN. This material has unique characteristics which make it suitable for a wide range of applications.

We have it available in block, rods, sheets and finished components. High precision tight tolerance components can be machined using a wide range of techniques including drilling, grinding, turning and milling.

The thermal conductivity of BNP2 is approximately 5x that of alumina, with a flexural strength of 30kg/mm2 which is comparable to that of alumina.

BNP 2 maintains a low dielectric loss and also has an ultra high purity level.

Please contact our technical sales team who will discuss your application and answer any technical issues.
