Kovar Bar Manufacturer, Supplier, and Stockists in India

Kovar Bar, a nickel-cobalt ferrous alloy, is extensively used in industrial manufacturing due to its unique properties and versatility. Its thermal expansion coefficient closely matches that of glass, making it an ideal choice for applications involving glass-to-metal seals. This compatibility allows Kovar Bar to be utilized in the production of electronic components, vacuum tubes, and other devices where reliable hermetic sealing is essential. Its ability to maintain structural integrity across a wide range of temperatures further enhances its applicability in demanding environments.

One of the standout properties of Kovar Bar is its excellent mechanical strength combined with good ductility. With a tensile strength of approximately 965 MPa and a yield strength of around 690 MPa, Kovar Bar provides robust performance under stress. Additionally, it exhibits significant elongation, typically around 30%, which allows for easy machining and fabrication without risking brittleness. The hardness of Kovar Bar, measured at Rockwell B90, ensures it can withstand wear and tear in industrial applications, making it a preferred material for components that require both durability and precision.

In terms of thermal and corrosion resistance, Kovar Bar excels in various environments. It can withstand extreme temperatures, with a melting point around 1350°C, making it suitable for high-temperature applications. Moreover, its corrosion resistance is noteworthy, performing excellently in both marine and chemical environments. This property is critical for industries such as oil and gas, aerospace, and telecommunications, where exposure to harsh conditions is common. The combination of these properties makes Kovar Bar a reliable choice for manufacturers seeking longevity and performance in their products.

Furthermore, Kovar Bar is available in various forms, including rods and bars, and can be customized to meet specific size requirements. Its typical applications span a wide range, including oil and gas, chemical processing, and electronic manufacturing. The material is exported globally, reaching markets in the USA, Canada, Germany, and beyond. By choosing Kovar Bar, manufacturers can benefit from its unique combination of thermal stability, mechanical strength, and corrosion resistance, ensuring high-quality production standards in their operations.
