Overview

Alloy 46 is a nickel-iron controlled expansion alloy containing 46% nickel. 46 Alloy is a controlled expansion alloy used mostly in electronic applications, especially for glass and ceramic seals. Alloy 46 is also known as Pernifer 462, NILO 464, and Glass-Seal 461.It has a fairly constant coefficient of thermal expansion from room temperature up to 932 °F (500 °C).

It has superior mechanical strength, heat, and corrosion resistance at elevated temperatures, making it ideal for aerospace and chemical processing applications.

Physical Constants

Mechanical properties

Corrosion Resistance

Alloy 46’s primary advantage over other materials is its high corrosion resistance. Even in severe environments, such as those in the aerospace industry, alloy 46 remains highly resistant to corrosion, oxidation, and erosion. Additionally, its resistance to acidic and alkaline solutions and seawater makes it an ideal choice for use in harsh marine environments.

Heat treatment

Alloy 46 is heat treated at 1100°C for eight hours, followed by a water quench. This process provides excellent tensile strength, making it highly desirable for industrial applications.Alloy 46 is non hardenable by heat treatment.
