Kovar® is a nickel-iron-cobalt alloy, made up of about 54% iron, 29% nickel, and 17% cobalt. It features a very low coefficient of thermal expansion (approximately 5 ppm/K) and offers excellent toughness. This material is known for its strong physical and mechanical properties and is suitable for deep drawing and punching processes. However, Kovar® is not resistant to corrosion in humid or wet conditions and should be protected with a corrosion-resistant coating. With a tensile strength of 530 N/mm², it is non-magnetic and can be easily soldered. Nilo® K tubes are available from Evek GmbH, your trusted supplier of nickel-based alloys with worldwide shipping. Kovar® is primarily used to create seals between glass and metal, making it ideal for metal-glass feedthroughs. It is also commonly used as a housing material in microelectronics and microsystems technology. Other typical applications for 1.3981 include: - X-ray tubes - Electronics (transistors and diodes) - Hermetic seals - Chemical industry (vacuum systems) Key features of Kovar®: - Extremely low thermal expansion - Excellent toughness - Strong physical and mechanical properties - Suitable for deep drawing and punching - Not resistant to corrosion - Good solderability - Non-magnetic Evek GmbH Online Shop offers 1.3912 tubes and a wide range of nickel alloys.
