Kovar Forgings
What is Kovar Forgings ?
Kovar forgings are precision-engineered parts made from a nickel-cobalt-iron alloy known for its controlled thermal expansion. This alloy is composed of nickel, cobalt, silicon, manganese, and iron. They are used where sealing to glass or ceramic is critical. Parag Metals is a trusted Kovar Forgings supplier, supplying high-performance materials.
Kovar forgings offer excellent machinability, dimensional stability, and uniform grain structure. These forgings are used in aerospace, electronics, and high-vacuum systems. Their stability at high temperatures and low expansion rate make them perfect for applications that involve extreme thermal changes. As a kovar forgings distributor, we offer competitive pricing without compromising on quality.

Our Kovar forgings are available in specific shapes and sizes to meet industrial needs. Hot forged bars start from 3/4″ and above. Forged blocks are available up to 200 lbs with 36″ in length. Each piece is crafted with precision to meet application requirements. Pricing depends on size, shape, and volume.
All our forgings go through strict quality checks, including ultrasonic and hardness testing. Packaging is done securely to avoid damage during transit. Every product meets ASTM F15 standards. We follow consistent quality procedures to ensure each batch meets performance expectations.
Advantages of Kovar Forgings
- Kovar has a thermal expansion coefficient similar to that of borosilicate glass, which minimizes stress and cracking when joined to glass or ceramics.
- Its compatibility with glass and ceramics makes it ideal for creating hermetic seals in electronic components, vacuum tubes, and feedthroughs.
- Forged Kovar exhibits excellent tensile strength, toughness, and resistance to deformation, making it suitable for high-stress structural applications.
- Kovar offers good resistance to oxidation and corrosion, which extends the lifespan of components in harsh environments.
- It maintains its shape and size under varying temperatures and mechanical loads, which is crucial for precision engineering and aerospace applications.
Uses of Kovar Forgings
- Used in lead frames, connectors, and semiconductor packages due to its ability to form hermetic seals with glass and ceramics.
- Ideal for creating the metal-to-glass seals in vacuum tubes, X-ray tubes, and certain types of bulbs.
- Suitable for components exposed to extreme heat and stress, like nozzles and turbo-pumps
- Used in precision parts, sensors, and instruments that require dimensional stability under extreme temperature variations.
- Suitable for components in cryogenic systems because it maintains strength and stability at very low temperatures.
