Aluminum Nitride Ring Descriptions
Aluminum nitride is a high performance material particularly suited to demanding electrical applications. We combine expansive technical understanding with a commitment to working with customers, ensuring that our material solutions meet exacting specifications whilst providing exceptional performance.
Aluminum nitride can be produced by dry press and sinter or by hot pressing with appropriate sintering aids, the result of these processes is a material that is stable at high temperatures in a range of inert environments including hydrogen and carbon dioxide atmospheres. Aluminum nitride is principally used in the electronics area, particularly when heat removal is an important function.
Aluminum nitride properties 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.
