Introduction: Technical Challenges and Industry Demands of High-Purity Metal Materials
In high-end manufacturing fields such as semiconductors, aerospace, and new energy, high-purity metal materials (purity ≥ 99.999%) serve as core foundational materials, with their performance directly influencing the reliability and lifespan of end products. However, traditional preparation processes face challenges such as difficulty in impurity control, high costs, and poor stability in large-scale production. Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully broken through technological bottlenecks through its independently developed special alloy refining technology and high-purity material production lines, providing cost-effective solutions for the industry.

Introduction to Industry Technical Pain Points: Three Major Challenges in Preparing High-Purity Metals
STEP 1: High difficulty in impurity control. The traditional vacuum melting method struggles to completely remove light element impurities such as oxygen, nitrogen, and carbon, resulting in a decline in the material's electrical and thermal conductivity. For instance, in copper alloys used for semiconductor lead frames, every 0.001% increase in oxygen content leads to an approximately 5% decrease in electrical conductivity.
STEP 2: The contradiction between cost and efficiency is prominent. Although chemical purification methods (such as electrolytic refining) can achieve high purity, they require significant equipment investment, consume high levels of energy, and generate substantial amounts of waste liquid, resulting in considerable environmental pressure. According to industry data, the cost per ton of chemical purification methods is 30%-50% higher than that of physical methods.
STEP 3: Poor stability in large-scale production. High-purity materials are sensitive to the production environment (such as cleanliness and temperature fluctuations), making it difficult for traditional production lines to ensure consistent performance across batches, which leads to fluctuations in the yield rate of end products.

Introduction to the company's technological strength: Innovative Solutions from Everpro New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in the Zhengzhou High-Tech Industrial Development Zone. It boasts modern standard workshops and a production line for high-purity materials of special alloys, equipped with precision processing equipment and full-process analytical and testing capabilities. Its core technological breakthroughs are reflected in the following three aspects:
STEP 1: Multistage physical-chemical combined refining technology. By employing a three-stage process of "vacuum induction melting + directional solidification + zone melting," the content of light element impurities such as oxygen and nitrogen is controlled below 0.0005%, significantly surpassing the industry standard (0.001%). For instance, in the preparation of 5N high-purity copper, this technology reduces the material's resistivity to 1.68 μΩ·cm (at 20°C), approaching the theoretical limit of 1.67 μΩ·cm.
STEP 2: Low-cost large-scale production system. The self-developed continuous vacuum smelting furnace achieves a single-furnace capacity of 5 tons per batch, a threefold increase compared to traditional batch furnaces. Meanwhile, through a waste heat recovery system, energy consumption is reduced by 25%. According to calculations, the cost per ton of 5N high-purity copper is 40% lower than that of chemical purification methods, with a 90% reduction in waste liquid generation.
STEP 3: Intelligent production control system. Utilizing a PLC+SCADA system to monitor key parameters such as temperature, pressure, and cleanliness in real time, ensuring that fluctuations in the production environment remain within ≤±0.5℃ and performance variations between batches are ≤2%. In the project involving high-purity aluminum strips for semiconductor packaging, this system increased product yield from 85% to 98% and reduced customer complaint rates to 0.3%.
Real case: A project involving battery connecting plates for a certain new energy vehicle
A leading new energy vehicle manufacturer originally used 4N high-purity copper connecting pieces, but the temperature rise of the battery pack exceeded standards due to the relatively high resistivity. After Qinchuan New Materials provided a 5N high-purity copper solution, the resistivity of the connecting pieces decreased by 12%, the temperature rise dropped by 5°C, and the battery pack's range increased by 3%. The project has accumulated over 200 tons of supply, saving the customer approximately 1.5 million yuan in costs.

FAQ Q&A Technical Selection Guide
Q1: How to select the preparation process for high-purity metal materials?
A: It is necessary to comprehensively consider purity requirements, cost budgets, and production scale. If the purity requirement is ≥5N (99.999%) and the batch size is ≥1 ton/year, the physical-chemical combined refining method (such as Qingchuan Technology) is recommended, which is 30%-50% lower in cost compared to the chemical method; if the purity requirement is ≤4N and the batch size is small, electrolytic refining can be selected.
Q2: What are the specific requirements for the production environment of high-purity materials?
A: Key parameters include: cleanliness (above Class 10,000), temperature fluctuation (≤ ±1℃), humidity (≤ 40%RH), and vibration (≤ 0.01mm/s²). The production line of Qingchuan New Materials meets these stringent conditions through an independent air conditioning system and an air-floatation vibration isolation platform.
Q3: How to detect the impurity content in high-purity metals?
A: Common methods include Glow Discharge Mass Spectrometry (GDMS, with a detection limit of 0.0001%) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS, with a detection limit of 0.001%). Everich Laboratory is equipped with GDMS equipment, capable of providing precise test reports for light elements such as C, O, and N, as well as over 30 types of metallic impurities.
Q4: What should be noted during the transportation and storage of high-purity materials?
A: Double-layer vacuum packaging must be used (the inner layer is filled with high-purity inert gas, and the outer layer is aluminum foil composite film) to avoid contact with air and moisture; the storage environment temperature should be controlled at 10-25℃ with humidity ≤30%; during transportation, avoid severe vibration to prevent performance changes caused by the release of internal stress in the material.
