Alloy 42 is an iron-nickel alloy containing 42% nickel. It exhibits low thermal expansion characteristics over a range of temperatures, which makes it particularly suitable for use in glass and ceramic seals. It finds application in a variety of electronic components and lead frames.

42 Alloy, a low expansion alloy, is very similar to Invar 36 with a slightly different Coefficient of Thermal Expansion. This nickel-iron alloy is ideal for lid, lead frames, stencil/etching, telecommunications and aircraft industry, offering a more affordable alternative to Kovar when a tight seal is not required.

42 Alloy has a virtually constant low rate of thermal expansion at temperatures up to approximately 650°F (343°C). Easily machined and formed hot or cold, 42 Alloy is also used extensively in the medical, electronics and automotive industries.

Let National Electronic Alloys help you analyze your business needs and objectives. Our procurement side and supply side experience can save you money and ensure that you make the best possible purchasing decisions.

Main purpose:

mainly used for soft glass and ceramic sealing, Make electronic tubes, transistors and integrated circuit leads, Frame and seal plug.

Supply status

There are rods, tube, rods, strip and wire.
