Nilo® K Kovar® K 1.3981 Alloy K pipe N08825 Round pipe 6x1-26х2mm (length : 1 meter x 10 st/pc, size : 11 x 1.25mm)

Length tolerance is +/-2mm.- Production time: 2-3 weeks. - Preparation for shipping: 2-3 business days. - Delivery time: Varies based on the shipping service. Please check our FAQ for details.Kovar® is a nickel alloy made up of about 54% iron, 29% nickel, and 17% cobalt. It is known for its very low thermal expansion coefficient of around 5 ppm/K and outstanding toughness. The alloy offers good physical and mechanical properties and can be processed through deep drawing and punching. However, Kovar® is not resistant to corrosion in moist or wet conditions, so it requires a protective coating. The 1.3981 grade has a tensile strength of 530 N/mm² and is non-magnetic. It is also easy to solder.You can find Nilo® K tubes in the Evek GmbH online shop.
