Technological breakthrough: precise matching, stable success
YIWU YITECH TRADING CO., LTD Kovar alloy is based on a unique composition design (29% nickel, 17% cobalt, and iron balance), which achieves a linear expansion coefficient that is almost consistent with that of borosilicate glass, ceramics and other materials (5×10⁻⁶/K to 10×10⁻⁶/K) in the temperature range of -60℃ to 450℃, effectively solving the cracking problem caused by thermal stress at the metal-non-metal sealing interface. The product has a tensile strength of more than 520MPa and has excellent machinability and corrosion resistance, making it particularly suitable for high-reliability precision device packaging.
Service advantages: Full-cycle escort for customer value
YIWU YITECH TRADING not only provides standardized alloy products but also customizes composite material solutions according to customer needs. For example, it's developed "oxygen-free copper core-Kovar alloy" composite material has a 400% increase in thermal conductivity and has been successfully applied in the field of high-power semiconductor packaging. At the same time, the company is equipped with a professional team to provide material selection consultation, process optimization, and after-sales technical support to help customers shorten the R&D cycle and reduce cost risks.
Future layout: Targeting emerging fields and leading material innovation
Facing cutting-edge tracks such as quantum computing and new energy, YIWU YITECH TRADING is accelerating the integration and innovation of Kovar alloy with nano-plating and 3D printing technology. The person in charge of the company said, "We will continue to invest in research and development to promote the development of Kovar alloy towards higher precision and lighter weight, and inject new momentum into global high-end manufacturing."
YIWU YITECH TRADING CO., LTD takes "materials create value" as its mission and is working with industry chain partners to jointly write a new chapter in precision manufacturing.
