Aluminum nitride ceramic positioning parts
Alias: AlN ceramic locating strips
Description：
The Aluminum nitride ceramic positioning parts have high hardness and strength, making them excellent in harsh physical environments, and have a wide range of applications in power electronics, high-temperature environments, high-performance computing, medical equipment, and aerospace.
Features:
1. High thermal conductivity
The thermal conductivity of aluminum nitride is as high as 170 W/m·K, which allows it to quickly absorb and conduct heat from heat sources (such as semiconductor devices), thereby ensuring the operational efficiency and stability of the equipment.
2. Good thermal stability
It can be used in aerobic environments up to 1000℃ and has good thermal shock stability (ΔT400℃), making it suitable for operating environments with high temperatures or large temperature changes.
3. High strength and hardness
The Aluminum nitride ceramic positioning parts have high hardness (Rockwell hardness R45N is 78.5, Vickers hardness 1122kg/mm2) and high strength (flexural strength of 470 MPa and compressive strength of 2100 MPa), making them excellent in demanding physical environments.
4. Low coefficient of thermal expansion
Its coefficient of thermal expansion is 3.2-3.4×10-6/℃, which is close to silicon, which makes it have excellent compatibility with semiconductor materials when the temperature changes, and reduces the stress caused by the difference in thermal expansion.
5. Excellent electrical insulation
With an electrical breakdown strength of up to 17-19 KV/mm and low dielectric losses, with 0 air permeability and water absorption, Aluminum nitride ceramics provide excellent thermal management capabilities without compromising their electrical insulation.
6. Chemical stability
Aluminum nitride ceramics have excellent chemical stability and are able to resist various chemical corrosion and oxidation.
7. Precision manufacturing
This ceramic material can be manufactured with high-precision molding and processing techniques that ensure the accuracy of its size and shape.
Applications:
1. High temperature environment
In high-temperature and high-pressure environments, such as the oil and gas industry, the high-temperature stability and corrosion resistance of Aluminum nitride ceramics make them an ideal choice.
2. Power semiconductors and power electronics
Including drive systems for frequency converters and electric vehicles, the heat generated by power elements in these systems needs to be controlled through efficient thermal management. Due to its excellent insulating properties, Aluminum nitride ceramic positioning parts are widely used in power and electronic equipment, such as insulation brackets, terminal blocks and connectors.
3. High-performance computing equipment
Such as servers and workstations, these devices generate a lot of heat and need to dissipate heat efficiently to maintain stable and efficient operation.
4. Electronic packaging
Aluminum nitride ceramic materials are also widely used in semiconductor packaging to help reduce heat buildup inside the package and improve overall device performance and reliability.
5. Aviation & Aerospace
In the aerospace sector, the high strength and heat resistance of Aluminum nitride ceramics allow them to be used in the manufacture of a wide range of high-performance components.
