Introduction: The Technological Battle in High-Purity Metals and Special Alloys
In high-end manufacturing fields such as aerospace, semiconductors, and new energy, the performance of high-purity metals and specialty alloys directly determines product reliability and lifespan. However, traditional preparation processes face challenges such as insufficient purity, composition segregation, and poor processability, which have become key bottlenecks restricting industry development. Qingchuan New Materials (Zhengzhou) Co., Ltd. has achieved breakthroughs in preparation processes, composition control, and performance optimization through independently developed advanced technologies, providing efficient solutions for the industry. This article will comprehensively analyze its technological advantages and application value, covering technical principles, practical cases, and selection guidelines.

Opening on industry technical pain points: Three major challenges of traditional craftsmanship
STEP1：Challenges in purity controlTraditional smelting processes are prone to introducing impurities, resulting in a metal purity below 99.99%, which fails to meet the stringent purity requirements for materials in high-end fields such as semiconductors and optical devices. For instance, in the preparation of semiconductor target materials, every 0.001% increase in impurity content shortens the target material's service life by over 30%.
STEP2：Challenges in component uniformitySpecial alloys require precise proportioning to achieve specific properties, but traditional processes struggle to avoid composition segregation, resulting in significant fluctuations in material performance. Taking nickel-based superalloys as an example, when composition segregation exceeds 0.5%, their high-temperature strength decreases by 15%-20%.
STEP3：Processing performance bottleneckThe hardness, toughness, and other parameters of high-purity metals and special alloys need to match the processing techniques; otherwise, issues such as cracking and deformation are prone to occur. For example, due to the insufficient ductility of high-purity tungsten, the yield rate of traditional rolling processes is below 60%, severely restricting production efficiency.

Introduction to the Company's Technological Strength: Innovative Solutions from Evergreen New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, specializes in the research, development, and manufacturing of high-purity metals and special alloys. It boasts modern standardized workshops and advanced production lines, equipped with high-precision processing equipment and comprehensive testing capabilities to ensure that its products meet international quality standards.
STEP1：Vacuum Induction Melting (VIM) technologyBy smelting in a vacuum environment, the incorporation of impurities is effectively avoided, elevating metal purity to over 99.999%. For instance, in the preparation of high-purity aluminum for semiconductors, the VIM process reduces impurity content from 0.01% to 0.0005%, extending the service life of target materials to twice that of traditional processes.
STEP2：Electroslag Remelting (ESR) TechnologyTo meet the demand for compositional uniformity in special alloys, the ESR process achieves secondary refining of metals by heating slag with electric current, controlling composition segregation within 0.1%. Taking nickel-based alloys for aero-engines as an example, the ESR process enhances their high-temperature strength to 1200 MPa, a 25% improvement over traditional processes.
STEP3：Synergistic process of cold rolling and heat treatmentTo address the bottleneck in the processability of high-purity metals, Qingchuan New Materials has developed a synergistic process combining cold rolling and heat treatment. By precisely controlling rolling temperature and annealing parameters, the ductility of high-purity tungsten has been increased by 30%, and the rolling yield has improved from 60% to over 90%.

FAQ: A Q&A Guide to Technology Selection
Q1: How to select the preparation process for high-purity metals?
A1: It requires comprehensive consideration based on material purity requirements and cost budget. If the purity requirement is ≥99.999%, vacuum induction melting (VIM) is the preferred choice; if the purity requirement ranges from 99.99% to 99.999%, electron beam melting (EBM) or zone refining (ZR) can be considered. Qingchuan New Materials has achieved large-scale production using the VIM process, reducing costs by 30% compared to EBM.
Q2: How to control the segregation of special alloy components?
A2: Electroslag remelting (ESR) is the optimal process for controlling composition segregation, reducing segregation from 0.5% to within 0.1%. By optimizing the slag composition and current parameters, Qingchuan New Materials has reduced the energy consumption of the ESR process by 15% and increased production efficiency by 20%.
Q3: How to solve the cracking issue in high-purity metal processing?
A3: It requires collaborative optimization in three aspects: rolling temperature, annealing process, and material purity. Qinchuan New Materials has reduced the rolling temperature of high-purity tungsten from 800°C to 600°C and shortened the annealing time from 4 hours to 2 hours through a coordinated cold-rolling and heat-treatment process, effectively avoiding cracking issues.
