Qingchuan New Materials: Professional Power in Iron-Nickel Fixed Expansion Sealing Alloy Field
In the field of special alloy materials, iron-nickel fixed expansion sealing alloys are widely used in industries such as electronics, aerospace, and precision instrument manufacturing due to their unique thermal expansion properties. As a company focusing on the research, development, and manufacturing of high-purity metals and special alloys, Qinchuan New Materials (Zhengzhou) Co., Ltd. has become a significant player in the field with its profound technical accumulation and modern production capabilities.

Step 1: R&D-driven, Technologically Advanced
Qingchuan New Materials, leveraging the区位 advantage of Zhengzhou High-tech Industrial Development Zone, has established a research and development team consisting of material science experts and engineers, focusing on the composition optimization and process improvement of iron-nickel fixed expansion sealing alloys. By introducing advanced vacuum melting technology and precise casting processes, the company has successfully developed alloy products with stable thermal expansion coefficients and excellent sealing properties, capable of meeting temperature matching requirements in various application scenarios. For example, the 4J29 alloy produced by the company has a thermal expansion coefficient fluctuation of less than ±1×10⁻⁶/℃ within the range of -60℃ to 400℃, significantly enhancing the reliability of electronic components.
STEP 2: Equipment Upgrade, Quality Assurance
The company's modernized standard workshop is equipped with multiple special alloy production lines, covering the entire process from raw material mixing, melting and casting to heat treatment processing. Among them, the vacuum induction melting furnace achieves precise control of alloy composition with an error rate lower than 0.05%; the CNC machining center ensures that the product size tolerance is within ±0.01mm. In addition, Qinchuan New Materials has established a comprehensive quality control system, strictly inspecting each batch of products through means such as spectral analysis, metallographic testing, and expansion coefficient testing, to ensure that performance indicators meet the requirements of ASTM F30-99 and GB/T 15018-2018 standards.

Step 3: Application Expansion, Service Upgrade
Qinchuan New Materials' products are widely used in fields such as electronic packaging, vacuum devices, and precision sensors. For instance, a communication equipment manufacturer used its 4J33 alloy as sealing material for microwave devices, which improved the product's temperature resistance by 30% and reduced the failure rate to below 0.5%. The company also offers customized services, adjusting alloy composition and processing techniques according to specific customer needs, and is equipped with a technical support team to assist in solving technical challenges in applications. Through continuous technological innovation and quality improvement, Qingchuan New Materials is gradually becoming a professional force in the iron-nickel fixed expansion sealing alloy field.
