In the rapidly evolving landscape of high-frequency electronics and aerospace engineering, the demand for stable, high-reliability materials has never been greater. Kovar (ASTM F15 alloy), a nickel-cobalt-ferrous alloy, stands as the gold standard for EMI (Electromagnetic Interference) shielding components due to its unique physical properties. Its coefficient of thermal expansion (CTE) is specifically designed to match that of borosilicate glass and alumina ceramics, making it indispensable for hermetic packaging.
Kovar provides exceptional magnetic permeability at low frequencies, effectively blocking external electromagnetic fields that could disrupt sensitive semiconductor performance in 5G and AI hardware.
With a CTE of approximately 5.1 × 10⁻⁶/°C, Kovar ensures that seals remain airtight during extreme temperature fluctuations in space and deep-sea environments, preventing mechanical stress failures.
Advanced Kovar shielding requires Ra < 0.3μm surface roughness to support high-quality gold or nickel plating, essential for corrosion resistance and solderability in military-grade assemblies.
Founded in November 2014, Xinyunyang has adhered to the business principles of Integrity, Innovation, Cooperation, and Sharing. We specialize in Kovar precision processing, deeply cultivating fields such as semiconductors, optical communications, aerospace, and medical devices.

The global supply chain for precision electronic components has shifted significantly towards integrated hubs that offer both material expertise and manufacturing scale. Chinese manufacturers, specifically those in the Pearl River Delta like Xinyunyang, provide a competitive edge through:
Immediate access to 4J29 Kovar raw materials and secondary processes like vacuum brazing, gold plating, and laser welding in a single geographic cluster.
Utilizing high-end 5-axis machining centers to achieve tolerances within ±0.005mm, meeting the stringent requirements of the aerospace and semiconductor industries.
Competitive pricing models optimized by intelligent production scheduling and high-volume throughput without compromising on REACH/RoHS compliance.
As we move towards the 6G era and widespread AI deployment, EMI shielding is no longer just about protection; it's about thermal-electromagnetic co-design. Modern solutions focus on:
