Overview

Name: 4J42 UNS K94100 /W. Nr.1.3917
SKU: 0

NILO alloy 42 (UNS K94100/W. Nr. 1.3917), a binary nickel-iron alloy containing 42% nickel. It has a low, and nominally constant, coefficient of expansion over the range 20-300°C (85-570°F). It is used for tooling for aerospace composites, thermostat rods, for semiconductor lead frames, in thermostatic bi-metal strip, and for glass sealing applications in microelectronic components, vacuum devices and electric lamp bulbs.

Corrosion Resistance

NILO alloy 42 has excellent corrosion resistance. It is a nickel-based superalloy with excellent corrosion resistance and high temperature strength.

It is important to note that although Alloy 42 has good corrosion resistance, corrosion is still possible when exposed to highly corrosive media or environments. Therefore, in the process of use, it is necessary to take corresponding protective measures according to the specific application environment and use conditions, such as surface coating, passivation treatment, etc., to enhance its corrosion resistance.

Thermal Treatments

Where maximum dimensional stability is required the alloys should be used in the annealed condition. Annealing can be carried out in the range 850°-1000°C (1560-1830°F) in a protective atmosphere.
