Sapphire lift pins are precision components made of sapphire (an aluminium oxide crystal) and are widely used in many fields.
Sapphire has a very high hardness, with a Mohs hardness of 9, second only to diamond, so sapphire lift pins have extremely strong wear resistance and scratch resistance. In addition, sapphire has excellent thermal stability and can maintain its performance in high-temperature environments, making it suitable for applications that require heat resistance.
In the electronics industry, sapphire lift pins are often used as substrates for semiconductor devices and are widely used for their excellent electrical insulation properties.
At the same time, sapphire needles are also used in optoelectronic devices, providing optical transparency and high strength, suitable for working in harsh environments.
Due to its excellent corrosion resistance, sapphire needles are also used in the chemical industry and medical instruments.
The production process of sapphire lift pins usually involves high temperature and high-pressure synthesis to ensure the integrity and purity of their crystal structure.
This makes sapphire lift pins an ideal choice for precision instruments, watches and other high-tech equipment.
With the advancement of science and technology, the application areas of sapphire lift pins are constantly expanding, showing their importance in modern industry.
