Nilo® K Kovar® K 1.3981 Alloy K pipe N08825 Round pipe 6x1-26х2mm (length : 1 meter x 10 st/pc, size : 20.5 x 1.75mm)

Length tolerance: +/-2mm- Production time: 2-3 weeks - Shipping preparation: 2-3 working days - Delivery time: Varies by parcel service (see FAQ for details)Kovar® is a nickel-based alloy composed of approximately 54% iron, 29% nickel, and 17% cobalt. It is known for its very low coefficient of thermal expansion (about 5 ppm/K) and outstanding toughness. With good physical and mechanical properties, Kovar® can be deep drawn and punched. However, it is not resistant to corrosion in humid or wet environments and should be coated for protection. The material 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.
