Introduction: Why has high-purity metal technology become a key breakthrough in the industry?
In the fields of aerospace, semiconductor manufacturing, and new energy, the performance of high-purity metals and special alloys directly determines the reliability and service life of end products. However, issues such as inadequate impurity control and low processing precision in traditional processes have long hindered industry development. Leveraging its independently developed precision processing technology and full-process inspection system, Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully achieved industry-leading levels, with impurity content in high-purity metal materials below 0.001% and processing precision reaching ±0.5μm, providing critical material support for high-end manufacturing sectors.

Opening on Industry Technical Pain Points: Three Core Challenges of Traditional Processes
STEP1：Challenges in impurity controlIn traditional smelting processes, non-metallic impurities such as oxygen and nitrogen in raw materials are difficult to completely remove, resulting in a reduction of over 30% in material conductivity, which directly affects the yield of semiconductor devices. For example, a photovoltaic enterprise experienced a 5% loss in cell conversion efficiency due to excessive oxygen content in the silver paste material used.
STEP2：Insufficient processing accuracyThe machining error of conventional turning processes reaches ±5 μm, which fails to meet the geometric tolerance requirements for thin-walled parts (thickness ≤ 0.2 mm) in the aerospace field, resulting in an assembly failure rate as high as 20%.
STEP3：Lagging detection methodsMost enterprises only use spectral analysis for composition detection, which cannot identify micron-scale defects, leading to sudden failures caused by the propagation of internal cracks in materials during service and resulting in significant economic losses.

Introduction to the company's technological strength: Three major technological barriers of Everich New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in Zhengzhou High-Tech Industrial Development Zone, boasting modern standard workshops and internationally leading production lines for special alloys. Its technological advantages are reflected in the following three aspects:
STEP1：Ultra-pure smelting technologyBy combining vacuum induction melting and electroslag remelting processes, the oxygen content in metallic materials is controlled below 0.0005% (the industry average is 0.002%), significantly enhancing material conductivity. For instance, the 5N high-purity copper (purity ≥ 99.999%) produced is used in semiconductor lead frames, reducing device leakage current to below 0.1 nA, reaching international advanced standards.
STEP2：Micron-level precision machining systemFive-axis simultaneous CNC machine tools combined with laser interferometer online detection are adopted to achieve a machining accuracy of ±0.5 μm and a surface roughness of Ra ≤ 0.2 μm. In a certain aero-engine project, the geometric tolerances of the machined titanium alloy blades were 40% better than the design requirements, helping the customer pass airworthiness certification.
STEP3：Full-process quality traceability systemFrom the entry of raw materials into the factory to the delivery of finished products, real-time data uploading is achieved through 12 inspection procedures (including direct-reading spectrometers, scanning electron microscopes, metallurgical microscopes, etc.), ensuring traceability for each batch of products. Its inspection reports are recognized by international organizations such as SGS and TÜV, with a customer re-inspection pass rate of 99.97%.

FAQ Q&A Technical Selection Guide
Q1: How to select a suitable supplier of high-purity metals?
A: We need to focus on examining three major indicators:
- Purity grade: Materials with a purity of 5N (99.999%) or higher are suitable for the semiconductor field, while 4N (99.99%) materials can be used in power electronics;
- Processing capability: The supplier must possess micron-level processing equipment and an online inspection system to ensure that geometric tolerances meet design requirements;
- Certification Qualifications: Prioritize enterprises that have passed ISO 9001 and AS9100D aviation quality management system certifications to reduce cooperation risks.
Q2: What are the special requirements for the storage conditions of high-purity metals?
A: Strict control of environmental humidity (≤30%RH) and temperature (20±2℃) is required to prevent surface oxidation of the materials. Everich New Materials offers vacuum double-layer packaging services, enabling the materials to maintain purity requirements for over 12 months when stored in a conventional warehouse.
Q3: How to avoid deformation in the processing of special alloys?
A: We need to follow three major principles:
- Process design: Adopt step-by-step processing + stress-relief annealing process, with a 0.3 mm allowance retained after each procedure;
- Parameter optimization: Control the cutting speed at 80-120 m/min and the feed rate at 0.05-0.1 mm/r;
- Clamping method: Utilize dedicated soft-jaw fixtures to minimize the impact of clamping force on thin-walled components. Qingchuan New Materials can provide customized machining solutions based on customer drawings, with deformation controlled within 0.02mm.
