    4J36 (similar grades: Invar, FeNi36, Invar Standard, Vacodil36) alloy, also known as Invar (INVAR) alloy, the Curie point of the alloy is about 230 ℃, below this temperature the alloy is ferromagnetic, with very low The expansion coefficient is higher than this temperature, the alloy is non-magnetic, and the expansion coefficient increases. Alloy control of carbon and manganese composition is very important. 4J36 has corrosion resistance in dry air at room temperature, while corrosion (rust) may occur in other harsh environments, such as humid air. The alloy is mainly used to manufacture components with approximately constant dimensions within the range of temperature changes, and is widely used in the radio industry, precision instruments, meters and other industries.The main supply form of the product:wire,strip,plate,bar,pipe.The minimum order quantity is 50kg.
