electronic radiating cooling AIN ceramic plate sheet
Reputation depends on quality, quality comes from Hard!
Aluninum Nitride Ceramic:
Aluminum nitride ceramics are mainly used for materials other than DDQ applications. This material is characterized by relatively low elongation (≧45%), relatively high hardness (≦180HB), and internal grain size grade of 8.0~9.0 Compared with DDQ materials, its deep drawing performance is relatively poor. It is mainly used for products that can be obtained without stretching, such as spoons, spoons, forks, electrical appliances, steel pipes and so on. But it has an advantage compared with DDQ material, that is, the BQ property is relatively better, which is mainly due to its slightly higher hardness. Stainless steel sheet is an inexpensive material, but customers have very high requirements for its surface quality. Various defects such as scratches, pits, sand holes, dark lines, creases, and pollution will inevitably appear in the production process of stainless steel sheets. Therefore, the surface quality, such as scratches and creases, is a high-grade material. It is not allowed, and defects such as pockmarks and sand holes are never allowed in the production of spoons, spoons, forks, because it is difficult to throw them away during polishing. It is necessary to determine the quality level of the table according to the degree and frequency of various defects on the surface to determine the product level.
Using AIN ceramics for heat resistance, melt erosion and thermal shock resistance, GaAs crystal crucible, Al evaporating dish, magnetic fluid power generation device and high temperature turbine corrosion resistant parts can be fabricated, and its optical properties can be used as an infrared window. The aluminum nitride film can be made into a high frequency piezoelectric element, a very large scale integrated circuit substrate, or the like.
Aluminum nitride heat-resistant, resistant to molten metal erosion, stable to acid, but easy to be eroded in alkaline solution. The AIN fresh surface is exposed to moist air and reacts to form a very thin oxide film. By utilizing this property, it can be used as a crucible and a die-casting mold material for smelting metals such as aluminum, copper, silver, and lead. AIN ceramics have good metallization properties and can be widely used in the electronics industry as an alternative to toxic cerium oxide.
