Aluminum Nitride Ceramics (AlN), also known as AlN ceramics, are gaining widespread attention for their outstanding thermal conductivity, low density, and excellent electrical insulation. With a thermal expansion coefficient similar to silicon, AlN ceramics are especially suited for applications requiring both efficient heat dissipation and electrical isolation.
Puwei offers a wide range of customizable AlN ceramic components, including discs, rods, tubes, rings, and complex shapes. We specialize in tight tolerance machining, fine grinding, and surface polishing to meet specific design and performance requirements.
One of the most popular products in our lineup is the AlN ceramic disc, often used in electronic substrates and heat management systems due to its dimensional stability at high temperatures. In inert atmospheres, AlN ceramics maintain their integrity, while in air, they form a protective oxidation layer effective up to 1370°C.

Thanks to these unique properties, AlN ceramic substrates are widely applied in circuit protection, heat exchangers, flame tubes, sealing gaskets, and even medical prosthetics and ceramic cutting tools.
Whether you’re in the electronics, automotive, or medical field, Aluminum Nitride Ceramics deliver the durability and performance your applications demand.
