4J33 Ceramvar Alloy
4J33 alloy, also known as iron nickel cobalt constant expansion alloy, is a precision alloy material with a specific coefficient of thermal expansion. Its main components include iron (Fe), nickel (Ni), cobalt (Co), as well as small amounts of chromium (Cr), molybdenum (Mo) and other elements. By precisely controlling the ratio and processing technology of each element, the alloy can maintain a relatively stable size change rate when the temperature changes, that is, it has an extremely low coefficient of thermal expansion or specific thermal expansion characteristics. This characteristic makes 4J33 alloy an ideal choice for manufacturing high-precision instruments, devices, and structural components
Leírás
4J33 Ceramvar Alloy is a fixed expansion sealing iron nickel cobalt alloy mainly used for matching sealing with 95% Al203 and other ceramics. Its main characteristics are that it has a linear thermal expansion coefficient similar to that of 95% AL203 ceramics in the range of -60-+600 degree
