Aluminum Nitride
- What is Aluminum Nitride?
Aluminum Nitride Powder (AlN) is a light grey or white ceramic material with a density of 3.26 g/cm³. Its high thermal conductivity and excellent electrical insulation make it valuable in the microelectronics industry. Although AlN surfaces oxidize in air at room temperature, the resulting aluminum oxide layer protects the material up to 1370°C. AlN can be metallized, enabling its use in electronic applications similar to alumina and beryllium oxide. Additionally, AlN ceramics are harder than traditional alumina ceramics, making them ideal for applications that require good wear resistance.

FAQs
Aluminum Nitride (AlN) products are highly valued for their exceptional properties, making them suitable for various advanced applications. Key features include high thermal conductivity (170-220 W/m·K), excellent electrical insulation, a high melting point (around 2200 °C), and low thermal expansion. AlN is chemically stable and resistant to most reagents, with high mechanical strength and wear resistance. It can form a protective aluminum oxide layer when oxidized, which withstands temperatures up to 1370 °C. Biocompatible and machinable into complex shapes, AlN can also be metallized for conductive paths, making it ideal for electronics, aerospace, automotive, and biomedical applications.
Yes, our samples are free. Generally speaking, our free samples are based on existing molds. There are many similar situations. We will change our own molds to produce the products you need. In this case, the samples are free. If the product you provide is too complicated, and we need to make a custom-made mold, under this condition, a mold fee is required, because it is very expensive.
Under normal circumstances, we recommend T/T payment, but if this payment method is not suitable for you, you can consider Western Union, which has a lower fee. If your amount is small, you can also use PayPal to pay, which is more convenient.
Factors affecting price fluctuations generally include raw material prices, epidemics, domestic energy issues, etc., but we will quote you the most suitable price under the premise of ensuring quality.
