Kovar Round Bar / Wire Supplier, Stockist

What is Kovar?

Kovar Bar and Wire are versatile, high-performance materials used in industries such as electronics, aerospace, automotive and medical device production. Kovar is composed of 29% Nickel, 17% Cobalt and 54% Iron which gives it unique characteristics that make it an ideal choice for applications requiring tight dimensional control. It has excellent thermal expansion properties which ensure a secure fit between components during extreme temperature fluctuations. Additionally, its superior strength makes it incredibly durable under pressure and vibration. The malleability of Kovar allows manufacturers to shape the material into complex shapes without compromising on performance. Its ability to be machined easily furthers its appeal for precision parts fabrication with intricate details.


Kovar is a nickel-iron-cobalt alloy with controlled thermal expansion properties. It is often used in hermetic sealing applications. It is tough and versatile and has a coefficient of thermal expansion similar to hard glass. Kovar alloy is made with extensive quality controls to ensure uniformity in physical properties.

What is Kovar?

Kovar Round Bars are an alloy made up of 29% nickel, 17% cobalt, 0.2% silicon, 0.3% manganese, and 53.5% iron. It is specifically known for its low coefficient of thermal expansion and is suitable for uses that require a matched expansion seal between metal and glass parts.

This nickel-iron-cobalt-based controlled expansion alloy matches both borosilicate glasses and ceramics. This material ensures it is a highly recommended alloy for hermetic sealing or glass or metal sealing uses.

What are Kovar and Wires?

Kovar Wires are a key component in many products. These alloys are made of nickel, cobalt, and iron and contain a low coefficient of thermal expansion. Like Kovar Sheets, Kovar Wires has unique qualities allow them to be fabricated into many different parts. Unlike many other alloys, Kovar Wires chemical composition can be controlled within very narrow limits, ensuring uniformity in thermal expansion.

Lint Steels is a renowned manufacturing company that offers the best quality Kovar round bars and wires. Our company places strong commitments towards client satisfaction through excellence, reliable quality, and competitive pricing of different products.
