

4J42 alloy, also known as Invar 42 alloy or Nilo 42, is a high-performance nickel-based Precision Alloy. It is composed of iron, nickel, cobalt, copper and other elements, with unique physical properties and a wide range of applications.

FEATURE

Low coefficient of expansion: 4J42 alloy has a very low coefficient of thermal expansion in a specific temperature range, which means that its size changes very little when the temperature changes, thus ensuring the accuracy and stability of the device. This feature makes it widely used in electronics, aerospace and other fields.
Good mechanical properties: The alloy exhibits high tensile strength and yield strength, as well as good elongation and hardness. This allows it to withstand high mechanical loads without deformation or fracture. In the aerospace and automotive industries, such high strength characteristics ensure the stability and safety of parts under complex working conditions.
Excellent corrosion resistance: 4J42 alloy is resistant to a variety of corrosive media and is suitable for use in harsh environments. This characteristic prolongs the service life of the equipment and makes it widely used in chemical industry, electric power and other fields.
Stable physical properties: Physical properties such as thermal conductivity, resistivity and specific heat capacity remain stable at high temperatures, ensuring the performance consistency of the alloy in different working environments.
