Aluminum Nitride Rod Descriptions

Aluminum Nitride RodAluminum nitride ceramic is a high-performance material particularly suited to demanding electrical applications. Aluminum nitride rod is stable at high temperatures in a range of inert environments including hydrogen and carbon dioxide atmospheres. It is principally used in the electronics area, particularly when heat removal is an important function.

The excellent properties of the AlN rod also make it particularly useful in the creation of corrosion-resistant products. Our unique approach to developing and manufacturing means that our engineers collaborate with customers to ensure that corrosion-resistant products or components consistently satisfy customer requirements.
