The shipment, manufactured to ASTM F15 and IEC 60191-2 standards, features outer diameters from 2 mm to 12 mm and wall thickness tolerances within ±0.02 mm. Each tube is cleaned, capped, and vacuum-sealed to prevent oxidation during the 18-day sea-and-rail journey via Ningbo to Port Said.
According to YITECH's export manager, the order was placed by a Cairo-based electronics packager that supplies hermetic feed-throughs for aerospace and telecom modules. To meet the customer's urgent ramp-up schedule, the company dedicated two production lines and completed the lot in 12 days, 20 % ahead of contract.
Kovar is an iron-nickel-cobalt alloy with favorable thermal expansion characteristics. The thermal expansion coefficient of Kovar is compatible with that of hard glass and ceramics. It is used in the production of electronic parts and in aerospace, vacuum sealing, and other high-end engineering industries. The Kovar alloy tubes, precision rolled and heat treated, feature high dimensional accuracy, and 500 kg of Kovar alloy are exported on this occasion. Their surface quality and stable performance, other than meeting material reliability and consistency, are also aligned with the Egyptian customers' stringent requirements.
Egypt, the second fastest industrializing nation on the African continent, has been focusing on electronics manufacturing, new energy, and high-end equipment. Kovar alloy tubes are a strategic material in vacuum devices, used domestically in cheap resonance laser equipment and lacking in local supply. Through domestic supply chain and logistics systems, Yiwu Yitech offers an integrated option of supplies, processing, and quality testing.
Fulfilling this order serves as proof to the Egyptian market of the quality that Chinese raw materials offer, while simultaneously showcasing the prowess of Chinese companies in the processing and exportation of high-performance materials. The company collaborates with foreign monitoring organizations to control alloy composition, mechanical properties, and dimension tolerances to ASTM standards and specific client technical requirements.
