Introduction
High-purity metals and special alloys, as core materials in high-end manufacturing, have their R&D and production technologies directly determining the performance ceilings in fields such as aerospace, new energy, and semiconductors. However, the industry has long faced challenges such as difficulties in purity control, poor composition uniformity, and low process stability. Qingchuan New Materials (Zhengzhou) Co., Ltd. (hereinafter referred to as "Qingchuan New Materials") has achieved key breakthroughs in the field of special alloys and high-purity materials by leveraging its independently developed precision machining technology and a comprehensive quality control system throughout the entire process. This article will analyze how Qingchuan New Materials resolves industry challenges through technological innovation from dimensions such as technical principles, practical cases, and parameter analysis.

Opening on the Pain Points of Industry Technology
STEP 1: Challenges in Purity Control
The preparation of high-purity metals (e.g., with a purity above 5N) requires strict control of impurity content to ppm or even ppb levels. Traditional smelting processes are prone to introducing non-metallic impurities such as oxygen and carbon, leading to a decline in material properties such as electrical conductivity and thermal conductivity. For example, in the field of semiconductor sputtering targets, a 0.1N decrease in purity may result in a 5%-10% drop in wafer yield.
STEP 2: Challenges in Component Uniformity
Special alloys (such as nickel-based superalloys) require the addition of multiple elements in combination to achieve specific properties, but uneven element distribution can lead to localized embrittlement or reduced corrosion resistance in the material. Taking turbine blades of aero-engines as an example, composition fluctuations exceeding 0.5% may trigger high-temperature fatigue cracks, directly threatening flight safety.
STEP 3: Bottleneck in Process Stability
The production of high-purity materials and special alloys is highly sensitive to parameters such as temperature, pressure, and atmosphere. Traditional production lines rely on manual experience for regulation, often resulting in batch-to-batch variation rates of 3%-5%, making it difficult to meet the stringent consistency requirements of high-end customers.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, is a professional enterprise dedicated to the R&D and production of high-purity metals and special alloys. Leveraging modern standard workshops, the company is equipped with internationally advanced precision processing production lines for special alloys and purification equipment for high-purity materials, forming a full-chain technological system covering "R&D - production - testing."
STEP 1: Core technology layout
• Purity enhancement technology: The combined process of Vacuum Induction Melting (VIM) and Electron Beam Melting (EBM) is employed to control oxygen content below 5ppm, achieving a purity level of 5N-6N to meet high-end demands such as semiconductor targets and optical coatings.
• Component Homogenization Technology: By utilizing multi-stage atomization powder production and Hot Isostatic Pressing (HIP) processes, the distribution deviation of alloying elements is controlled to ≤0.3%, significantly enhancing the material's fatigue life and corrosion resistance.
• Intelligent process control: AI algorithms are introduced to monitor key parameters such as smelting temperature (±2℃) and pressure (±0.1kPa) in real time, achieving a batch-to-batch variation rate of ≤1% and ensuring stable output of products that comply with international standards such as ASTM and AMS.
STEP 2: Practical Application Cases
In the battery connection tab project of a new energy vehicle enterprise, the customer required a copper-based alloy with a purity of ≥5N and an electrical conductivity of ≥98% IACS. By optimizing VIM melting parameters (temperature: 1650°C, vacuum level: 10⁻³ Pa) and incorporating directional solidification technology, Everich New Materials successfully reduced the impurity content to 8 ppm and increased the electrical conductivity to 98.5% IACS. The product passed UL certification and achieved bulk supply.

FAQ Q&A Technical Selection Guide
Q1: How to choose a suitable high-purity metal supplier?
A1: Three key indicators require focused assessment:
• Purity testing capability: Require suppliers to provide ICP-MS (Inductively Coupled Plasma Mass Spectrometry) test reports to ensure impurity content ≤ 10 ppm;
• Process stability: Verify performance variations between batches through small-batch trial production, with a variation rate ≤ 2%;
• Certification Qualifications: Prioritize enterprises that have passed ISO 9001 and AS9100D (Aerospace Quality System) certifications, such as Qingchuan New Materials, which has obtained multiple international standard certifications.
Q2: How to solve the problem of uneven composition in special alloys?
A2: Optimization can be carried out from three aspects:
• Raw material control: Select high-purity raw materials (such as 5N-grade metals) to reduce the introduction of impurities;
• Process selection: Adopt multi-stage atomization powder production (particle size D50 ≤ 50 μm) combined with HIP process (temperature 1200 °C, pressure 150 MPa) to enhance compositional uniformity;
• Detection and verification: Cross-detection via EDS (Energy Dispersive Spectroscopy) and XRF (X-ray Fluorescence Spectrometry) ensures that the deviation in elemental distribution is ≤0.5%.
Q3: What are the environmental requirements for the production of high-purity materials?
A3: The following conditions must be met:
• Cleanliness: The workshop achieves ISO Class 7 (Class 100) cleanliness to prevent dust contamination;
• Humidity control: Relative humidity ≤ 40% to prevent material from absorbing moisture and oxidizing;
• Atmosphere protection: Argon protection is used during the smelting process (oxygen content ≤ 5 ppm) to prevent the incorporation of non-metallic impurities.
