expansion wire 4J36 ALLOY wire FeNi alloy rod









The expansion wire, specifically the 4J36 alloy wire, is a type of low-expansion alloy material. It is characterized by its extremely low coefficient of thermal expansion, which makes it highly suitable for applications requiring high precision and stability. The 4J36 alloy wire is composed mainly of iron and nickel, with nickel content typically around 36%. This composition gives it excellent dimensional stability over a wide temperature range.
The FeNi alloy rod is another form of this material, available in a rod shape. It shares the same low-expansion properties as the 4J36 alloy wire, making it ideal for manufacturing mechanical components, tools, and other parts where minimal thermal expansion is crucial. Both the 4J36 alloy wire and FeNi alloy rod are widely used in industries such as precision instruments, aerospace, electronics, and mechanical engineering.
