Nilo® K Kovar® K 1.3981 Alloy K pipe N08825 Round pipe 6x1-26х2mm (size : 26 x 2mm, length : 1 meter x 5 st/pc)

Length tolerance: +/-2mm- Production time: 2-3 weeks - Shipping preparation: 2-3 business days - Delivery time: Varies by parcel service (see FAQ for details)Kovar® is a nickel alloy made up of approximately 54% iron, 29% nickel, and 17% cobalt. It is known for its very low thermal expansion coefficient (about 5 ppm/K) and excellent toughness. With strong physical and mechanical properties, Kovar® can be processed through deep drawing and punching. However, it is not resistant to corrosion in moist environments and requires a protective coating for such conditions. The material, also known as 1.3981, has a tensile strength of 530 N/mm² and is non-magnetic. It is easy to solder with standard solder.You can purchase Nilo® K tubes in the Evek GmbH online store.
