Everything You Need to Know About FeNi42 Glass Sealing Alloy

1. What is FeNi42 Glass Sealing Alloy?

FeNi42 Glass Sealing Alloy is a type of Nickel-Iron alloy commonly used in glass-to-metal sealing applications. It has a thermal expansion coefficient well-matched to borosilicate and soda-lime glass, making it ideal for creating hermetically sealed environments in electronic components such as vacuum tubes, transistors, and sensors.

2. What are the key properties of FeNi42 Glass Sealing Alloy?

FeNi42 Glass Sealing Alloy exhibits a low coefficient of thermal expansion, high electrical resistivity, and excellent corrosion resistance. These properties make it an excellent choice for applications where a reliable and durable seal between metal and glass is required. The alloy also has good mechanical strength and can withstand temperature changes without cracking or deforming.

3. How is FeNi42 Glass Sealing Alloy used in practical applications?

FeNi42 Glass Sealing Alloy is often used in the manufacture of hermetically sealed electronic components such as vacuum tubes, sensors, and connectors. The alloy is typically formed into a component shape, and then attached to a glass component using a controlled heating process. The thermal expansion match between the alloy and glass ensures a tight seal that prevents the ingress of moisture and contaminants, preserving the integrity of the enclosed electronics.In summary, FeNi42 Glass Sealing Alloy is a versatile and reliable material for creating hermetically sealed environments in electronic components. Its unique combination of properties, including low thermal expansion, high resistivity, and corrosion resistance, make it an ideal choice for applications where a durable and long-lasting seal is essential.
