Chung Metal provides Da Nang, Vietnam-based Nilo Alloy 42 Bars and Rods with controlled expansion alloys for precision electrical and electronic devices. Nilo 42 is commonly applied due to its coefficient of expansion well-suited for most ceramic and glass materials. It provides outstanding bonding performance in hermetic seals. Chung Metal guarantees each bar to be quality-checked for dimensionality accuracy and stability.
Nilo 42 is 42% nickel with balance iron. It possesses a thermal expansion coefficient of ~4.6 µm/m-°C, tensile strength of approximately 430 MPa, and good resistance to corrosion and oxidation. The alloy is soft magnetically and suitable for uses under tight dimensional tolerance requirements due to temperature change.
