In Delhi, India, Daksh Sheets and Plates is a reputable producer and supplier of high-grade metal sheets and plates. Daksh specialises in providing a broad range of industrial-grade materials, such as Kovar Sheets and Plates, with an emphasis on precision engineering and client satisfaction. Strict quality control and cutting-edge technology are used in the manufacturing of our products to guarantee superior performance in demanding settings. Having been in the business for many years, Daksh has established a strong reputation for dependability, prompt delivery, and affordable prices, which has made us a popular option for customers in the engineering, electronics, and aerospace industries.
The main constituents of Kovar Sheets and Plates are 29% Nickel, 17% Cobalt, and the remaining iron, with trace amounts of silicon and manganese. The extremely low coefficient of thermal expansion provided by this special alloy composition is comparable to that of borosilicate glass. Kovar has a high tensile strength of roughly 500–700 MPa, good machinability, and outstanding dimensional stability. In addition, it has exceptional magnetic permeability and hermetic sealing qualities, which make it perfect for specialised applications needing minimal heat distortion and high precision.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Because of their remarkable thermal expansion compatibility with glass and ceramics, Kovar Sheets and Plates are widely used in high-reliability electronic and scientific applications. They are crucial to the production of hermetically sealed glass-to-metal parts, such as headers, feedthroughs, and enclosures for electronic packages. Because of these characteristics, Kovar is perfect for use in high-vacuum systems, medical devices, telecommunications, and aerospace instrumentation. Kovar guarantees structural stability under thermal cycling in the semiconductor industry. Relay bases, sensor housings, and other precision components needing little expansion and magnetic interference can benefit from its special thermal and magnetic characteristics.
