Founded in November 2014, Xinyunyang Precision Technology Co., Ltd. has established itself as a premier global supplier of Kovar (4J29) precision components. We operate on the principles of Integrity, Innovation, and Cooperation, focusing specifically on the intricate needs of high-reliability industries.
Our core competitiveness lies in the deep cultivation of Kovar precision processing technology, catering to semiconductors, optical communications, aerospace, and medical devices. As Israel continues to lead in global R&D, we provide the essential hardware backbone for miniaturized, customized, and hermetically sealed electronic systems.
Israel is home to global defense giants like IAI, Elbit Systems, and Rafael. These entities require 4J29 Kovar shells for missile guidance systems and satellite transponders where thermal stability is non-negotiable between -65°C and +400°C.
With massive R&D centers for Intel and Nvidia in Haifa and Jerusalem, the demand for hermetic packaging that protects sensitive silicon from moisture while matching the expansion of borosilicate glass is soaring.
From ingestible cameras to implantable sensors, the biocompatibility and vacuum-tight sealing capabilities of Kovar alloy make it a staple for Israel's burgeoning Bio-convergence sector.
Kovar (ASTM F15 / 4J29) is a vacuum-melted, iron-nickel-cobalt alloy. Its chemical composition is controlled within extremely narrow limits to ensure precise, uniform thermal expansion properties. In the context of Israel’s high-tech manufacturing, this alloy is the "golden standard" for glass-to-metal and ceramic-to-metal seals.
| Property | Value (Typical) | Israeli Industry Benefit |
|---|---|---|
| CTE (20-400°C) | 4.6 – 5.2 x 10⁻⁶/K | Matches Hard Glass (Pyrex) |
| Thermal Conductivity | 17.3 W/m·K | Efficient Heat Dissipation |
| Tensile Strength | 450 MPa | Structural Integrity in Flight |
Leveraging China's mature industrial ecosystem allows for a 30-40% reduction in production costs compared to domestic Israeli or US-based machining, without sacrificing MIL-SPEC quality.
For Israeli startups in the "Seed to Series B" phase, our CNC machining capabilities allow for rapid iteration of Kovar shells—moving from CAD to physical prototype in as little as 7 days.
We provide full documentation for Israeli customs, including RoHS, REACH, and Conflict-Free Mineral declarations (ESG), ensuring smooth transit to Ashdod or Ben Gurion Airport.
