Chung Metal manufactures Nilo Alloy 36 Bars and Rods, also known as Invar 36, in Da Nang, Vietnam. This iron-nickel alloy is known for its near-zero thermal expansion, making it critical for applications requiring high dimensional precision. Nilo 36 is widely used in aerospace, scientific, and metrology instruments. Our products are available in a variety of diameters and lengths to meet exacting design specifications.
Nilo 36 contains 36% nickel and remainder iron. It is characterized by a very low coefficient of thermal expansion (~1.2 µm/m-°C), tensile strength approximately 450 MPa, and great dimensional stability. The material is resistant to corrosion in dry conditions and machinable and weldable with common methods.
