Aluminum Nitride

Polished ceramic, quartz, high dielectric, sapphire, glass, fused silica, AlN and numerous other hard materials can be shipped from stock. Aluminum Nitride (AlN) features a high thermal conductivity of 170 W/mK, excellent dielectric properties, and a low thermal expansion similar to silicon. These characteristics make AlN ideal for electrically insulating nontoxic substrate material for hybrid, power and microwave electronics applications. Some items may have notch or flat.

Aluminum Nitride Ceramic

Aluminum Nitride Ceramic is the perfect material choice when high thermal conductivity and electrical insulation properties are needed. Aluminum Nitride has a combination of high dielectric strengthening, high electrical insulation properties, and low thermal expansion.  AlN Aluminum Nitride is optimal for hybrid, power and microwave electronics applications where an electrically insulating nontoxic substrate material is required.  It is the ideal material for a wide variety of uses in the growing Semiconductor, Aerospace, Defense and Medical Industries.

Aluminum Nitride Advantages

The difference between Aluminum Nitride Ceramic material and other electrically insulative and sometimes thermally insulative is its unique ability to dissipate heat quickly while maintaining maximum efficiency. Aluminum Nitride’s thermal profile is similar to Silicon, making it a popular choice for semiconductor wafer processing applications.

Valley Design’s Aluminum Nitride products manage rapid heat buildup and offer the unique ability to dissipate heat in components such as heat sink spreaders and a wide variety of other electronic applications where high temperatures are often an issue. Aluminum Nitride substrates are perfect for power modules and LED applications.
