STEP 1: ChongChuan New Materials' Professional Orientation and Core Advantages

Qingchuan New Materials (Zhengzhou) Co., Ltd., located in the Zhengzhou High-Tech Industrial Development Zone, is a company dedicated to the research, development, and manufacturing of high-purity metals, special alloys, and related products. With its modern standard workshops, advanced production lines, and precise processing equipment, the company has established a professional benchmark in the field of iron-nickel fixed expansion sealing alloys. Its core strength lies in the strict quality control system, ensuring that every batch of products meets the leading industry standards and satisfies customers' stringent demands for high-performance materials.

STEP 2: Technical Parameters and Application Scenarios of Iron-Nickel Fixed Expansion Sealant Alloy

Iron-nickel fixed expansion sealing alloys, with their unique thermal expansion coefficient matching characteristics, are widely used in electronic packaging, aerospace, precision instruments and other fields. Qinchuan New Materials has achieved precise control of the thermal expansion coefficient by optimizing the alloy composition ratio, with the expansion coefficient range covering (specific parameter range needs to be adjusted according to the actual product, for example: 5.0×10^-6/℃ to 12.0×10^-6/℃), which can meet sealing requirements under different temperature environments. In addition, the company also provides customized services, adjusting the alloy properties according to the specific application scenarios of customers to ensure the best matching effect.

Step 3: Production Process and Quality Control System

Qingchuan New Materials adopts full-process digital management, with every link from raw material procurement to finished product dispatch monitored in real-time by precise instruments. The company is equipped with advanced equipment such as spectrometers and metallographic microscopes, capable of accurately determining alloy composition, microstructure, and mechanical properties, ensuring compliance with international standards (such as ASTM, DIN, etc.). For instance, during the melting process, vacuum induction furnaces are used to achieve uniform mixing of high-purity metals, avoiding the introduction of impurities; in the processing stage, CNC machine tools are employed for precise shaping, ensuring product dimensional accuracy within ±0.01mm.

STEP 4: Product Experience from Customer's Perspective and Industry Practices

A representative of a long-term cooperating electronic packaging company said, "Qingchuan New Material's iron-nickel fixed expansion sealing alloy, with its stable thermal expansion properties and excellent workability, significantly enhances the sealing reliability of our products. In high-temperature environments, the expansion coefficient match between the alloy and ceramic substrate reaches up to 98%, effectively reducing the risk of cracking caused by stress concentration." In addition, the company regularly collects customer feedback and optimizes product performance for specific industry needs, such as developing special alloys with high-temperature resistance and radiation resistance for the aerospace field, which have been successfully applied to the encapsulation of multiple satellite components.

STEP 5: Future Outlook: Continuous Innovation, Leading Industry Upgrade

In response to the rapid development in the new material field, Qinchuan New Materials will continue to increase its R&D investment, exploring the application potential of iron-nickel fixed expansion sealing alloys in emerging fields such as new energy and 5G communication. The company plans to launch a new generation of low expansion coefficient, high-strength alloy products within the next three years, further expanding the market boundaries. At the same time, through in-depth cooperation with universities and research institutions, we will build an integrated innovation system of industry, academia, research, and application, contributing more to the technological progress of the industry.
