Introduction: Technological Breakthroughs in High-Purity Metals and Special Alloys
In high-end manufacturing fields such as semiconductors, aerospace, and new energy, the performance of high-purity metals and specialty alloys directly determines the reliability and lifespan of products. However, traditional preparation technologies often encounter challenges such as insufficient purity, composition segregation, and low processing precision, resulting in significant fluctuations in material performance and high production costs. Leveraging its modern production base in Zhengzhou High-Tech Industrial Development Zone, Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully overcome multiple technological bottlenecks by introducing internationally advanced production lines and precision processing facilities, combined with comprehensive analytical and testing capabilities throughout the entire process, providing solutions for high-purity, high-performance materials to the industry. This article will analyze Qingchuan New Materials' technological breakthrough path from three dimensions: technical principles, practical cases, and parameter analysis.

Opening on Industry Technical Pain Points: Three Major Challenges of Traditional Preparation Technologies
STEP 1: Challenges in purity control
Due to equipment precision limitations, traditional smelting processes struggle to control metal impurity content below the ppm (parts per million) level. For instance, in the preparation of high-purity aluminum for semiconductors, the impurity content of elements like iron and silicon must be below 0.001%, whereas conventional processes often exhibit impurity fluctuations ranging from 0.005% to 0.01%, resulting in a more than 30% decline in material conductivity and directly impacting chip performance.
STEP 2: Insufficient composition uniformity
Special alloys (such as nickel-based superalloys) require precise proportioning of multiple elements (such as chromium, cobalt, and molybdenum) to achieve specific properties. Due to uneven cooling rates, traditional casting processes are prone to causing composition segregation, with element content deviations in local areas exceeding 5%, leading to a 20%-30% reduction in the material's high-temperature strength and shortening the service life of aero-engine blades.
STEP 3: Limited machining accuracy
The processing of high-purity metals and special alloys requires meeting micron-level precision requirements. Due to insufficient equipment rigidity, traditional turning and milling processes often result in a surface roughness exceeding Ra0.8 μm, whereas high-end applications (such as optical lens substrates) require a surface roughness below Ra0.2 μm; otherwise, light scattering losses will increase by over 15%.

Introduction to the company's technological strength: Everpro New Materials' three major technological layouts
Qingchuan New Materials (Zhengzhou) Co., Ltd., located at No. 16 Jinzhan Street, Zhengzhou High-Tech Industrial Development Zone, possesses modern standardized workshops and the following core technological capabilities:
STEP 1: International advanced production line configuration
The company has introduced equipment such as Germany's ALD vacuum melting furnace and Japan's Koyo precision rolling mill, enabling the preparation of metals with a purity of ≥99.999% (5N grade). For instance, in the production of 5N-grade high-purity copper, through a three-stage vacuum distillation process, the oxygen content is controlled below 0.0002%, an 80% reduction compared to traditional processes, and the electrical conductivity is increased to 101% IACS (International Annealed Copper Standard), meeting the demands for high-frequency cables used in 5G communication base stations.
STEP 2: Precision Processing and Composition Control Technology
Laser cladding and electron beam welding technologies are employed to achieve atomic-level uniform distribution of special alloy components. Taking IN718 nickel-based superalloy as an example, through multi-pass rolling and heat treatment processes, the segregation coefficients of elements such as chromium, cobalt, and molybdenum are controlled within the range of 0.95-1.05. The endurance strength at 650℃ reaches over 1000 MPa, representing a 15% improvement over the industry average, making it suitable for key components such as aero-engine turbine disks.
STEP 3: Full-process analysis and detection capability
Equipped with devices such as Optical Emission Spectrometer (OES) and Inductively Coupled Plasma Mass Spectrometer (ICP-MS), it enables real-time monitoring of metal purity and alloy composition. For instance, in titanium alloy production, the fluctuation range of oxygen content is controlled within ±0.001% using an online oxygen analyzer, ensuring a stable material fatigue life of over 10⁷ cycles and meeting the 20-year service life requirement for offshore engineering equipment.

FAQ Q&A Technical Selection Guide
Q1: How to select the preparation process for high-purity metals?
A1: The process should be selected based on the target purity and material properties. For example, high-purity copper of 5N grade or above requires a combined process of vacuum melting and zone refining, achieving a purity of 99.9995% (5N5 grade) with an oxygen content of ≤0.0001%; whereas high-purity aluminum of 3N-4N grade can be produced through electrolytic refining, reducing costs by 40%. Qinchuan New Materials can customize process routes according to customer requirements to ensure a balance between purity and cost.
Q2: How to avoid cracks in the processing of special alloys?
A2: Crack formation is related to the material's thermal expansion coefficient and machining stress. For example, when machining titanium alloy, the cutting speed should be controlled at 60-80 m/min, the feed rate at 0.05-0.1 mm/r, and high-pressure coolant (pressure ≥ 10 MPa) should be used to reduce the cutting temperature. Everchamp New Materials has optimized machining parameters through simulation software, reducing the crack rate from the industry average of 5% to below 0.5%.
Q3: How to verify whether the material performance meets the standards?
A3: It requires a combination of multiple testing indicators. For example, superalloys need to be tested for endurance strength (≥1000 MPa) and fracture toughness (≥50 MPa·m¹/²) at 650℃; high-purity metals require testing for electrical conductivity (≥100% IACS) and oxygen content (≤0.0002%). Qingchuan New Materials provides third-party testing reports to ensure data traceability.
