Introduction
High-purity metals and special alloys, as core materials in high-end manufacturing, have their preparation technologies directly determining product performance and application boundaries. However, issues such as difficulty in purity control, poor compositional uniformity, and low production efficiency in traditional processes have long hindered the industry's advancement towards high-end development. Leveraging its independently developed advanced preparation technologies, Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully overcome multiple technological bottlenecks, providing high-performance material solutions for fields such as aerospace, semiconductors, and new energy. This article will systematically analyze the technological advantages and industry value of Qingchuan New Materials from dimensions including technological principles, process innovations, and application cases.

Opening on the Pain Points of Industry Technology
In the field of high-purity metals and specialty alloys, technological bottlenecks are primarily manifested in three aspects: First, purity control is difficult. Traditional smelting processes are prone to introducing impurities, making it challenging to achieve material purity above 99.999% and failing to meet the demands of high-end sectors such as semiconductors and aerospace. Second, component uniformity is poor. Alloying elements are prone to segregation during the smelting process, resulting in significant fluctuations in material properties and affecting product consistency. Third, production efficiency is low. Traditional processes rely on manual operations, leading to long production cycles and difficulties in achieving large-scale, automated production. These issues not only increase manufacturing costs but also constrain the localization process of high-end materials.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, is a high-tech enterprise specializing in the research, development, and manufacturing of high-purity metals and special alloys. Leveraging modern standardized workshops and advanced production lines, the company has established a full-process technological system encompassing material design, smelting, refining, forming, and testing, with its core strengths reflected in the following three aspects:
STEP 1: Advanced Technology and Equipment
The company has introduced internationally leading Vacuum Induction Melting Furnace (VIM) and Electron Beam Melting Furnace (EBM), combined with independently developed inert gas protection technology, enabling metal purity to reach 99.9999% (Grade 6N) with impurity content below 0.1 ppm. For instance, in the preparation of high-purity tungsten targets for semiconductors, the VIM-EBM combined process controls oxygen content below 0.0002%, significantly outperforming the industry average (0.001%).
STEP 2: Component Uniformity Control Technology
To address the issue of alloy segregation, Qingchuan developed a "multi-stage homogenization treatment process" that achieves an alloy element distribution uniformity (σ) of ≤0.5% by controlling the melting temperature gradient (±5℃) and stirring speed (50-200 rpm), representing a threefold improvement over traditional processes. Taking the nickel-based superalloy GH4169 used in aerospace engines as an example, after adopting this process, the standard deviation of the material's room-temperature tensile strength decreased from 15 MPa to 5 MPa, significantly enhancing product consistency.
STEP 3: Intelligent Production System
The company has established an intelligent production platform based on the industrial internet, integrating PLC control systems with online inspection equipment to monitor key parameters such as melting temperature, pressure, and composition in real time. It automatically adjusts process parameters through AI algorithms, reducing production cycles by 40% and manual intervention by 70%. Currently, this system has been applied to a high-purity metal production line with an annual output of 500 tons, achieving a product qualification rate of 99.2%.

FAQ Q&A Technology Selection Guide
Q1: What are the preparation processes for high-purity metals and special alloys? How do we choose among them?
A: Common processes include Vacuum Induction Melting (VIM), Electron Beam Melting (EBM), Arc Melting (ARC), etc. The selection should consider material purity requirements, composition complexity, and production scale:
- Purity ≥ 99.999%: The combined VIM+EBM process is preferred for effectively removing gaseous and non-metallic impurities;
- Alloys with complex compositions: Employ a multi-stage homogenization treatment process to control the smelting temperature gradient and stirring parameters;
- Mass production: Integrate an intelligent production system to achieve automated adjustment of process parameters through PLC control.
Q2: How to evaluate the performance of special alloys? What are the key testing indicators?
A: Performance evaluation should be based on three aspects: chemical composition, physical properties, and processability.
- Chemical composition: ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is employed to detect impurity content, with a purity requirement exceeding 99.999%;
- Physical properties: Tensile strength (≥800 MPa), yield strength (≥550 MPa), and elongation (≥15%) are tested using a tensile testing machine (ASTM E8 standard);
- Processability: Evaluate the forgeability, weldability, and thermal treatment stability of materials. For example, nickel-based alloys must meet a requirement of enduring strength ≥ 300 MPa for 1000 hours at 650°C.
Q3: In which specific cases are Everpro New Materials' technological advantages reflected?
A: Taking high-purity molybdenum targets for semiconductors as an example, the oxygen content in molybdenum targets prepared by traditional processes reaches 0.001%, leading to particle defects during the sputtering process and affecting chip yield. Qingchuan has reduced the oxygen content to 0.0002% through the combined VIM-EBM process and inert gas protection technology, increasing the target sputtering rate by 20% and raising the chip yield from 92% to 98%. Currently, this product has been supplied in bulk to leading enterprises such as SMIC and Yangtze Memory Technologies.
