Kovar Wire
What is Kovar Wire ?
Kovar wire is a nickel-iron-cobalt alloy known for its low thermal expansion, which easily connects with glass and ceramic. It is made of nickel, cobalt, silicon, manganese, and iron. This makes it ideal for glass-to-metal sealing in high-precision applications. Parag Metals is a leading Kovar wire supplier, delivering high-quality alloys across industries.
Kovar wire is widely used where a tight bond between metal and glass is needed. It is used in electronic packaging, power tubes, transistors, diodes, and lightbulbs. It plays a key role in microwave tubes, x-ray and vacuum tubes, hybrid circuits, and other sensitive electronics. Our wires heat resistance, reliability, and dimensional stability are critical. Kovar wire for sale is available at competitive prices, depending on quantity, dimensions, and custom requirements.
