Hassan Sheets and Plate Manufacturer and Supplier, based in Riyadh, Saudi Arabia, is your go-to source for top-notch **Kovar Sheets and Plates**. This material is essential in precision engineering and electronics. Kovar is celebrated for its remarkable thermal expansion properties and its ability to create hermetic seals, making it a popular choice in the electronic, aerospace, and medical fields. At Hassan, we offer Kovar products that adhere to international standards, available in various sizes and thicknesses. With a solid reputation for quality and prompt delivery, we’ve become a trusted partner for clients throughout Saudi Arabia and the broader Middle East industrial landscape.
Kovar Sheets and Plates are made up of about 29% Nickel, 17% Cobalt, and the rest Iron. This unique blend gives Kovar a thermal expansion coefficient that closely matches that of glass and ceramics, which is perfect for creating glass-to-metal or ceramic-to-metal seals. It boasts a tensile strength ranging from 517 to 689 MPa and maintains its shape across a wide temperature spectrum. Kovar is magnetic, easy to machine, and has good thermal conductivity, with a melting point around 1450°C. These characteristics make it a favored choice for applications that require high reliability and vacuum sealing.
