Nilo® K Kovar® K 1.3981 Alloy K pipe N08825 Round pipe 6x1-26х2mm (size : 8 x 1mm, length : 1 meter x 10 st/pc)

Length tolerance is +/-2mm.- Production time: 2–3 weeks - Preparation for shipping: 2–3 working days - Delivery time: depends on the parcel service (see FAQ for details)Kovar® is a nickel alloy made up of approximately 54% iron, 29% nickel, and 17% cobalt. It stands out for its very low coefficient of thermal expansion (about 5 ppm/K) and excellent toughness. This material offers solid physical and mechanical properties and is suitable for processes like deep drawing and punching. However, Kovar® is not corrosion-resistant in moist or wet conditions and requires an additional protective coating. The alloy (1.3981) has a tensile strength of 530 N/mm² and is non-magnetic. It also features good solderability.You can find Nilo® K tubes in the Evek GmbH online shop.
