4J33 pins
4J33 pins are made of 4J33 alloy, which is a metal material with special physical and chemical properties and is widely used in electronics, aerospace, precision instruments and other fields.
The density of 4J33 precision alloy is 8.27g/cm3, and the material is a ceramic sealing alloy, belonging to the iron nickel cobalt constant expansion ceramic sealing alloy. 4J33 precision alloy and 4J34 precision alloy are ceramic sealing alloys developed based on the characteristics of ceramics in China. In the temperature range of -60 ℃ to 600 ℃, 4J33 precision alloy has a linear expansion coefficient similar to 95% AI2O3 ceramic. In use, the selected ceramic should match the expansion coefficient of the alloy.
Application:
In the field of electronic components: 4J33 pins are often used to manufacture key components such as seals, electric vacuum devices，connectors and lead frames due to their good thermal expansion matching performance and high temperature stability.Due to its excellent thermal stability, low expansion coefficient and good processing properties, 4J33 pins can provide stable connection effects and good sealing performance.
