A FULL range of copper-cored steel alloys for making glass-to-metal seals used in electrical switches and motor controls, where size and conductivity are important, is available from Anomet Products.
Copper-cored steel alloys combine the conductivity of copper with low thermal expansion materials and feature a complete metallurgical bond which provides total hermetic sealing between the metals.

Permitting the use of smaller and lighter pins, they are offered in 0.5mm to 10mm sizes with 2:1 and 3:1 ratios of the alloy to the copper core.

Supplied on spools, reels, or wrapped coils, they are available as Alloy 52 Nickel-Iron, Kovar Nickel-Iron-Cobalt, Alloy 42-6 Nickel-Chromium, and Alloy 446SS Iron-Chromium, each with a copper core (100% IACS minimum conductivity).

Any customer specified temper is offered, with dimensional tolerances to ±.01mm, depending upon diameter.

Anomet alloys are priced according to type and quantity. Literature and evaluation samples are available upon request.
