Introduction
As the "cornerstone" of modern industry, high-purity metallic materials have their preparation technology directly determining the performance ceilings in fields such as aerospace, semiconductors, and new energy. However, traditional processes face challenges such as difficulty in impurity control, poor grain uniformity, and high energy consumption, which restrict the development of high-end manufacturing. Leveraging its independently developed precision machining technology for specialty alloys, Qingchuan New Materials (Zhengzhou) Co., Ltd. has achieved breakthrough progress in the preparation of high-purity metallic materials. This article will analyze, from dimensions such as technological principles, process advantages, and application cases, how the company resolves industry challenges through innovative technologies and provides references for technology selection.

Opening on the Pain Points of Industry Technology
In the aerospace sector, engine turbine blades must endure temperatures exceeding 1,500°C and extreme stress, yet traditional nickel-based alloys, due to excessive impurity content (e.g., sulfur and phosphorus levels >0.005%), are prone to thermal fatigue cracking, reducing service life by over 30%. In the semiconductor industry, tungsten targets with 99.999% purity and grain size deviations >5μm can cause uneven sputter coating, leading to a 15% decline in chip yield. Industry research indicates that annual global losses in the high-end metal materials market due to process defects exceed $20 billion, with core challenges centered on impurity control, grain uniformity, and energy consumption optimization.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, is equipped with modern standard workshops and a precision processing production line for special alloys. Its core equipment includes Vacuum Induction Melting Furnace (VIM), Electron Beam Cold Hearth Melting Furnace (EBCHM), and Plasma Rotating Electrode Process (PREP) powder-making equipment, enabling full process control from raw material purification to finished product inspection.
STEP 1: Impurity Control Technology
Through the combined process of VIM melting and EBCHM secondary refining, the content of harmful elements such as sulfur and phosphorus is reduced to below 0.001%, and the oxygen content is controlled within 5 ppm, meeting the ASTM E1019 standard. For example, in a GH4169 alloy project for an aero-engine, the material's fatigue life increased by 40% after adopting this process, passing GE Aviation certification.
STEP 2: Optimization of grain uniformity
The powder prepared using PREP equipment has a particle size distribution with D50 = 50 ± 5 μm. When combined with hot isostatic pressing (HIP) forming technology, the grain size deviation of the finished product is ≤ 2 μm, meeting the stringent uniformity requirements for semiconductor target materials. Feedback from a chip manufacturer indicates that after using Qingchuan tungsten target materials, the coating thickness deviation decreased from ±8% to ±3%, and the yield increased to 98%.
STEP 3: Energy Consumption and Cost Optimization
The self-developed circulating cooling system reduces smelting energy consumption by 25%. When combined with the automated production line, the production cost per ton of materials decreases by 18% compared to the industry average. Currently, the company has an annual production capacity of 500 tons of high-purity metal materials, with products certified under the ISO 9001:2015 quality management system and covering 12 fields, including aerospace, semiconductors, and new energy.

Summary of Technical Advantages
The technological advantages of Qingchuan New Materials are reflected in three aspects: first, full-process impurity control, achieving "zero pollution" transfer from raw materials to finished products; second, precise regulation of grain size to meet the demand for material consistency in high-end manufacturing; third, dual optimization of energy consumption and cost to enhance the product's market competitiveness.

FAQ: A Q&A Guide to Technology Selection
Q1: How to select high-purity metal materials suitable for the aerospace field?
A: Aerospace materials must meet requirements for high-temperature strength, fatigue resistance, and corrosion resistance. Qinchuan New Materials reduces impurity content to below 0.001% through the VIM+EBCHM process and, combined with HIP forming technology, enables the GH4169 alloy to achieve a tensile strength of 1030 MPa at 650°C and a fatigue life of 10⁷ cycles, making it suitable for key components such as engine turbine blades and combustion chambers.
Q2: What are the purity requirements for metallic materials in the semiconductor industry?
A: Semiconductor target materials must achieve a purity of 99.999% with a grain size deviation of ≤5 μm. Qingchuan New Materials employs the PREP powder-making + HIP forming process, producing tungsten target materials with a purity of 99.9995% and a grain size D50 of 50 ± 2 μm, meeting the coating requirements for 12-inch wafers and having passed verification by manufacturers such as SMIC.
Q3: How can the preparation costs of high-purity metal materials be controlled?
A: Qingchuan New Materials optimizes costs through three aspects: First, it independently develops a circulating cooling system, reducing smelting energy consumption by 25%; second, it adopts automated production lines to minimize manual intervention, resulting in a 30% decrease in labor costs per ton; third, it achieves economies of scale through large-scale production (with an annual capacity of 500 tons), spreading fixed costs and enabling product prices to be 15%-20% lower than those of imported materials.
