Overview Of 3D Printing Alloy Metal Materials Iron Nickel Alloy InVar36 Metal Powder

Iron Nickel Alloy InVar36 Metal Powder refers to the InVar36 metal powder of iron-nickel alloy used for 3D printing. InVar36 is a special type of iron-nickel alloy, also known as Invar 36 or alloy 36. This alloy mainly comprises iron (about 63.8%) and nickel (about 36%) and contains a small amount of carbon and chromium. InVar36 is famous for its extremely low coefficient of thermal expansion, meaning its size changes very little when temperature changes. Therefore, it is widely used in applications that require high precision and dimensional stability, such as aerospace, precision instruments, and electronic equipment.
