Home > Kovar Sheets and Plates
Wai Nickel Alloys is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar. They specialize in high-quality Kovar Sheets and Plates, crafted for precision and performance in demanding industrial applications. These products are made from a nickel-cobalt-iron alloy that features controlled thermal expansion, making them perfect for sealing with glass and ceramics. Wai Nickel Alloys is committed to maintaining tight dimensional tolerances, delivering a superior surface finish, and adhering to international standards, ensuring reliability and consistency. Their Kovar Sheets and Plates are widely utilized in the electronics, aerospace, and instrumentation sectors, where thermal compatibility and high stability are essential.
The composition of Kovar Sheets and Plates includes about 29% nickel, 17% cobalt, and the remainder iron, along with trace amounts of manganese, silicon, and carbon. This specific blend provides a controlled coefficient of thermal expansion that aligns with borosilicate glass, as well as impressive tensile strength (around 520 MPa) and good ductility. The alloy retains its mechanical and magnetic stability even when subjected to fluctuating thermal conditions. Kovar also boasts excellent oxidation resistance in controlled environments and is easy to work with for forming, welding, and machining, making it a top choice for high-precision fabrication.
