Kovar Round Bar
What is Kovar Round Bar ?
Kovar round bar is a nickel–cobalt–iron alloy known for its low and consistent thermal expansion. This round is used in glass-to-metal seals and electronic packaging. It contains about 29% nickel, 17% cobalt, 0.2% silicon, 0.3% manganese, and the rest iron. These bars have a tensile strength of 518 MPa and a yield strength of 276 MPa which ensures stability and strength. Parag Metal is a trusted name in the industry and a leading supplier of Kovar round bars, providing high-quality bars to meet strict performance needs.
Kovar rod is available in many sizes and shapes. Diameter ranges from 5 mm to 500 mm, with lengths between 9 to 12 metres. Width varies from 10 mm to 2500 mm. Available forms include round, rod, square, hollow, hex, triangle, rectangle, threaded, flat bar and T-bar. Surface finishes include cold drawn, bright drawn, hot rolled, peeled and turned, smooth turned and more. These options help match specific project demands.

Kovar round bars are used where tight thermal control is needed. They are utilized in electronic parts, vacuum systems, and aerospace. They are resistant to cracking which make them ideal for critical components. Strength, formability, and bonding with glass or ceramics make them reliable. The kovar bar price is based on size, form, thickness and finish.
Each bar goes through quality checks to meet ASTM F15 / ASME SF15 standards. We conduct hardness, tensile, and chemical tests. Kovar bars are carefully packed to avoid damage during shipment. As a kovar bar stockist, we provide bars in various sizes. Contact us to discuss your requirements.
