Introduction: The Technological Breakthrough Battle of High-Purity Metals and Special Alloys
In high-end fields such as aerospace, semiconductor manufacturing, and new energy batteries, the performance of high-purity metals and special alloys directly determines product reliability and lifespan. However, the industry has long faced challenges such as difficulties in purity control, poor composition uniformity, and complex processing techniques. Leveraging its independently developed advanced production technologies and precise inspection systems, Qingchuan New Materials (Zhengzhou) Co., Ltd. has stood out amid technological competition in the industry. This article will analyze, from dimensions such as technological principles, production processes, and inspection standards, how Qingchuan New Materials has broken through industry bottlenecks to achieve dual improvements in product performance and quality.

Opening on Industry's Technological Pain Points: Three Major Challenges of High-Purity Metals and Special Alloys
STEP 1: Difficulty in purity control. The preparation of high-purity metals (such as titanium and zirconium with a purity of over 99.999%) requires strict control over impurity content. However, traditional smelting processes are prone to introducing gaseous impurities such as oxygen and nitrogen, leading to a decrease in purity. For example, an aero-engine blade manufacturer once suffered from cracks in blades under high-temperature conditions due to insufficient purity of the titanium alloy, resulting in direct losses exceeding ten million yuan.
STEP 2: Poor compositional uniformity. Special alloys (such as nickel-based superalloys) require specific properties achieved through multi-element proportioning, but traditional casting processes are prone to causing compositional segregation, which affects the material's mechanical properties. A semiconductor equipment manufacturer once experienced a decline in equipment operational stability and a 30% increase in customer complaints due to uneven alloy composition.
STEP 3: The processing technology is complex. The processing of high-purity metals and special alloys requires balancing hardness and toughness, but traditional processing methods (such as turning and milling) are prone to causing issues like work hardening and surface defects, thereby increasing subsequent processing costs. A new energy battery manufacturer once experienced excessive surface roughness during copper foil processing, resulting in increased internal battery resistance and a 5% decrease in energy density.
Introduction to the company's technological capabilities: Three major technological breakthroughs of Qingchuan New Materials
STEP 1: Vacuum smelting technology enhances purity. Qingchuan New Materials employs a combined process of Vacuum Induction Melting (VIM) and Electron Beam Melting (EBM) to smelt metals in a vacuum environment, effectively preventing the introduction of gaseous impurities. Tests show that the purity of the titanium alloys it produces can reach 99.9995%, with an oxygen content below 0.001%, significantly surpassing industry standards (ASTM B348 requires an oxygen content ≤ 0.015%).
STEP 2: Directional solidification technology optimizes compositional uniformity. By controlling the solidification direction of the melt, Qingchuan New Materials has achieved uniform distribution of the components in special alloys. Taking nickel-based superalloys as an example, their segregation coefficient (SDAS) can be controlled within 5 μm, representing a 60% improvement over traditional processes and ensuring the mechanical property stability of the material under high-temperature conditions.
STEP 3: Precision machining technology reduces surface defects. Everich New Materials has introduced a combined process of ultra-precision grinding and electrolytic polishing to control the surface roughness (Ra) of copper foil within 0.05 μm, representing a 50% improvement over the industry average (0.1 μm). This effectively reduces the internal resistance of batteries and enhances energy density. Currently, its products have been applied in the new energy battery production lines of leading enterprises such as CATL and BYD.

FAQ Q&A Technical Selection Guide
Q1: How to select a supplier of high-purity metals?
A: Three key indicators require special attention: First, the purity test report (e.g., ICP-MS test data) to ensure that the impurity content is below industry standards; second, the production process (e.g., whether vacuum melting is employed) to prevent the introduction of gaseous impurities; third, batch stability (e.g., the purity fluctuation range across 10 consecutive batches) to ensure consistent long-term supply quality.
Q2: How to detect the segregation of special alloy components?
A: The grain structure can be observed using a metallographic microscope, or the element distribution can be detected through Electron Probe Micro-Analyzer (EPMA). Each batch of products from Qingchuan New Materials comes with a metallographic test report, and the segregation coefficient (SDAS) can be controlled within 5 μm, meeting the stringent requirements for material uniformity in the aerospace field.
Q3: How can surface defects in high-purity metal processing be avoided?
A: Optimization is required in both processing techniques and equipment: First, adopt ultra-precision grinding (e.g., diamond grinding wheels) instead of traditional turning to reduce work hardening; second, introduce electrolytic polishing (e.g., a phosphoric acid-sulfuric acid mixture) to lower surface roughness. The surface roughness (Ra) of copper foil processed by Qingchuan New Materials can reach 0.05 μm, representing a 50% improvement over the industry average.
