1. What is UNS K94100?

UNS K94100(Alloy 42) is a nickel-iron alloy with 41-43% nickel, engineered for a low coefficient of thermal expansion (CTE ~4.9 µm/m·K), ensuring dimensional stability from -100°C to 400°C. This makes UNS K94100 material ideal for applications requiring matching expansion with glass or ceramics, such as electronic packaging and precision instruments. Compared to UNS K93600 (Invar 36), UNS K94100 has a higher CTE, making it better for sealing with higher-expansion materials like soft glass.

Gangsteel’s UNS K94100 alloy steel plate is crafted for precision engineering, offering a reliable alternative to nickel alloy steel grades like UNS N08904 or UNS S31254.
