Precision Alloy 51 (UNS N14052): Technical Specifications and Properties

Technical Passport for Alloy 51 (UNS N14052)

Alloy 51, classified under UNS N14052 and also known by trade names Pernifer 51 or VDM Alloy 51, is a precision iron-nickel alloy. Its key technological feature is a strictly controlled and stable coefficient of thermal expansion (CTE) over a wide temperature range. EV Group China supplies certified rolled metal products made from this alloy, which is indispensable in the production of high-precision measuring instruments, components for the radio-electronic industry, and in the construction of cryogenic equipment.

Chemical Composition of Alloy 51 (nominal values)

EV Group China guarantees that the supplied Alloy 51 has a chemical composition that precisely conforms to international standards. This ensures the absolute reproducibility of its physical properties, including magnetic permeability and thermal stability, within the operational parameters specified by engineers.

Mechanical Properties at Room Temperature (20°C)

The mechanical characteristics of Alloy 51 provide an optimal balance between tensile strength and ductility. This ratio is a critically important parameter for critical assemblies and components operating under conditions requiring high positioning accuracy and minimal elastic and plastic deformations.

Physical Properties and Temperature Dependencies

The nominal density of the material is 8.2 g/cm³. Key physical constants, such as modulus of elasticity and thermal conductivity, demonstrate a predictable and documented dependence on temperature. This allows design engineers to accurately model the behavior of components made from Alloy 51 under real operating conditions and during temperature fluctuations.
