Kovar® is a nickel alloy, which is composed of approx. 54% iron, 29% nickel and 17% cobalt. The material is characterized by a low coefficient of thermal expansion of approx. 5 ppm / K and excellent toughness. The material has good physical and mechanical properties and can be processed by deep drawing and punching. It is not corrosion-resistant in damp and wet environments and must be coated with an additional corrosion-resistant protective layer. 1.3981 has a tensile strength of 530 N / mm² and cannot be magnetized. The quality is easy to solder with solder.

Nilo® K pipes are available in the Evek GmbH online shop. We are a reliable supplier for nickel base alloys and we ship worldwide.

Since Kovar® enables a connection between glass and metal, it is mainly used for metal-to-glass feedthroughs. The material is also used in the field of microelectronics and microsystem technology as a housing material. Other fields of application of 1.3981 are

  • X-ray tubes;
  • Electronics (transistors and diodes);
  • various hermetic seals;
  • Chemistry (vacuum systems).

The following features distinguish Kovar®

  • extremely low coefficient of thermal expansion;
  • excellent toughness;
  • good physical and mechanical properties;
  • can be deep drawn and punched;
  • not corrosion resistant;
  • easily solderable with tin solder;
  • not magnetizable.

Evek GmbH Online Shop offers 1,3912 tubes. Get the nickel alloys and more from Evek GmbH.
