Nilo K (Kovar) / UNS K94610 / 1.3981 / NiCo2918

Nilo K – Kovar / EN 1.3981 / 29NK

Precision grade NILO alloy K (UNS K94610) has a complex ferritic-nickel composition with cobalt additions (stainless steel KOVAR). The composition also contains minor inclusions of molybdenum, silicon, manganese, carbon, chromium, copper and aluminum.

An alloy of this type has a narrow specific scope. Its temperature coefficient of linear expansion corresponds to borosilicate glass, which is used for the production of lamp bulbs.

You always have the opportunity to buy stainless steel of this type in our company, whose specialists will answer any questions and advise if necessary. The domestic analogue is 29HK stainless steel.

Features and application

Nilo K (Kovar) alloy is necessary for the manufacture of electrical contacts-pins passing through glass lamps. Ideally soldered to glass, forming a reliable and high-quality connection during this process.

It is in demand in optical production, it works in the widest temperature range. The alloy is used to manufacture equipment used on space satellites.

Standard rolled metal alloy for industrial use is produced. You can purchase wire, rods, pipes, strips and other types of rolled products at the most affordable prices in our catalog.
