Al Summan Metals, a highly regarded manufacturer and supplier based in Dubai, UAE, specializes in producing high-quality **Kovar Bars and Rods** that comply with demanding industrial and technological standards. These Kovar products are renowned for their outstanding thermal expansion compatibility with glass and ceramics, which makes them a preferred option for precision, durability, and reliability in critical applications. Al Summan Metals uses advanced manufacturing methods and stringent quality control practices to ensure consistent mechanical performance and accurate dimensional precision. Serving industries such as electronics, aerospace, and vacuum technology, the company provides Kovar solutions that stand out in performance, longevity, and operational efficiency, particularly in settings that require exact thermal and mechanical stability.
Kovar Bars and Rods consist mainly of nickel (29%), cobalt (17%), and iron (making up the balance), producing an alloy with a precisely regulated coefficient of thermal expansion. This distinctive makeup enables Kovar to expand and contract in step with borosilicate glass, effectively avoiding thermal stress in seals and joints. From a mechanical standpoint, Kovar bars and rods offer remarkable tensile strength, excellent ductility, and consistency over a broad temperature range. These traits make them ideal for uses that demand high dimensional precision and reliable performance during thermal cycling.

Kovar rods, made up mainly of iron, cobalt, and nickel, resist galvanic corrosion because their electrochemical properties are similar to those of most alloys, lowering the risk when combined with compatible materials.
Kovar bar can indeed be welded, though it demands specialized methods and safeguards owing to its distinctive makeup and thermal expansion characteristics. Careful heat management and appropriate filler metals are crucial.
Kovar rods are generally available in diameters spanning 1/8" to 4" and can be up to 12 feet long. Available finishes include mill, polished, and brushed surfaces suited to a range of applications.
Kovar Bars and Rods are utilized in industries demanding accurate thermal and mechanical compatibility. They are commonly applied in electronic components, glass-to-metal seals, vacuum tubes, and hermetic packaging. Within the aerospace and semiconductor fields, Kovar rods act as connectors, electrodes, and structural parts capable of withstanding thermal cycling. Their distinctive combination of mechanical strength and matched thermal expansion ensures reliability, precision, and durability in demanding applications. Kovar bars and rods play an essential role in producing high-performance components across technology-driven and industrial environments.
We supply products accompanied by mill test certificates as well as third-party test certificates, guaranteeing the highest standards of quality and compliance.
