Precision Alloy 52 (UNS N14052): Technical Overview and Properties

Technical Specification of Alloy 52 Precision Alloy

Alloy 52, classified as UNS N14052, is a binary iron-nickel precision material designed for applications requiring a strictly controlled Coefficient of Thermal Expansion (CTE). EV Group China supplies this alloy in the form of calibrated rods, bars, and precision wire, ensuring consistent physical and mechanical characteristics for mission-critical components in high-tech industries.

Elemental Composition of Alloy 52

Operational stability and specific physical properties of the material are achieved through strict adherence to a binary composition, where nickel and iron are alloyed in an equiatomic ratio, ensuring predictable thermal behavior.

Mechanical Properties at Room Temperature

Alloy 52 possesses a balanced complex of mechanical properties, combining high ductility with sufficient strength. This combination is essential for the production of hermetic glass-to-metal seals and components for vacuum electronics, where forming without compromising structural integrity is required.

Physical Constants and Thermal Properties

The nominal density of Alloy 52 is 8.3 g/cm³. A key characteristic is the presence of the Curie point (the inflection point on the CTE curve), which determines its application in heat-sensitive assemblies and bimetallic elements operating under cyclic thermal loads.
