Alloy 52

Alloy 52 is a nickel-iron alloy known for its excellent thermal expansion properties, high electrical resistivity, and good corrosion resistance.

Alloy 52 consists primarily of nickel (Ni) and iron (Fe), with nickel being the major component. The alloy is specifically formulated to exhibit a low and constant coefficient of thermal expansion (CTE) over a wide temperature range.

One of the notable features of Alloy 52 is its high electrical resistivity, which enables efficient electrical insulation and helps minimize unwanted electrical losses.

Alloy 52 exhibits good corrosion resistance in various environments, including atmospheric conditions, freshwater, and mild alkaline or acidic solutions. It is generally resistant to oxidation and can withstand prolonged exposure to moisture or humid environments.
