Introduction: Technical Challenges and Industry Demands of High-Purity Metals and Special Alloys
In high-end manufacturing fields such as semiconductors, aerospace, and new energy, the performance of high-purity metals (e.g., with a purity of over 99.999%) and special alloys (e.g., high-temperature alloys and corrosion-resistant alloys) directly determines product reliability. However, traditional manufacturing processes often encounter technical bottlenecks such as difficulty in impurity control, poor composition uniformity, and significant processing deformation, resulting in low product yields and high costs. Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully overcome multiple industry challenges through its independently developed precision machining technology and full-process inspection system, providing stable high-performance material solutions for high-end manufacturing.

Opening on Industry Technical Pain Points: Three Core Challenges in Manufacturing High-Purity Materials
STEP1：Difficulty in impurity controlHigh-purity metals require impurity content to be controlled at ppm (parts per million) or even ppb (parts per billion) levels. Traditional smelting processes are prone to introducing non-metallic impurities such as oxygen and carbon, resulting in decreased electrical conductivity and corrosion resistance of the materials. For example, if the oxygen content in high-purity copper for semiconductors exceeds the standard, it will significantly reduce the chip's heat dissipation efficiency.
STEP2：Poor composition uniformitySpecial alloys require specific performance (such as high-temperature strength and fatigue resistance) achieved through multi-element proportioning, but traditional casting processes are prone to causing composition segregation, affecting material consistency. Taking nickel-based superalloys for aero-engines as an example, composition fluctuations exceeding 0.1% may lead to blade cracking under high temperatures.
STEP3：Significant processing deformationHigh-purity metals and special alloys exhibit high resistance to plastic deformation, and traditional processing methods (such as forging and rolling) are prone to causing issues like cracks and residual stresses, resulting in a yield rate of less than 60%. For instance, improper deformation control during the processing of zirconium alloy tubes for nuclear power can reduce their corrosion resistance, posing a threat to reactor safety.

Introduction to the company's technological strength: Three major technological breakthroughs of Everpro New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, is equipped with modern standard workshops and internationally advanced production lines for special alloys and high-purity materials. Its technological strength is reflected in the following three aspects:
STEP1：Combined technology of vacuum induction melting (VIM) and electron beam melting (EBM)Low-melting-point impurities (such as sulfur and phosphorus) are removed via VIM, and then gaseous impurities (such as oxygen and nitrogen) are further reduced using EBM, achieving a metal purity of over 99.9995%. For example, the high-purity molybdenum targets it produces are used in the semiconductor display field, with an oxygen content of ≤3 ppm, meeting the requirements for 4K/8K ultra-high-definition displays.
STEP2：Multidirectional die forging and isothermal rolling processTo address the challenge of deformation in special alloy processing, Qingchuan developed multidirectional die forging technology, which achieves uniform material deformation through multidirectional pressing, thereby reducing the risk of cracks. Combined with isothermal rolling process, it maintains material plasticity at high temperatures and reduces processing residual stress to ≤50 MPa. The GH4169 alloy bars produced for aero-engines exhibit a grain size of ASTM Grade 6 after processing, with a 30% improvement in fatigue life.
STEP3：Full-process inspection systemFrom the entry of raw materials into the factory to the delivery of finished products, Everflow has established over 20 testing indicators covering chemical composition, physical properties, and microstructure. For instance, it employs Glow Discharge Mass Spectrometry (GDMS) to test metal purity with an accuracy of 0.1 ppm and utilizes Electron Backscatter Diffraction (EBSD) to analyze grain orientation, ensuring material isotropy. Its testing data can be traced back to international standards (such as ASTM and ISO), providing quality assurance for high-end customers.

FAQ Q&A Technical Selection Guide
Q1: How to select the manufacturing process for high-purity metals?
A: The process must be selected based on the material type and purity requirements. For instance, vacuum induction melting (VIM) can be used for metals with a purity requirement of ≤99.99%; if ≤99.999% is required, electron beam melting (EBM) must be combined. Qingchuan's VIM+EBM process can meet purity demands ranging from 5N to 6N (99.999%-99.9999%) and is suitable for fields such as semiconductors and photovoltaics.
Q2: How to solve the problem of significant deformation during the processing of special alloys?
A: Deformation can be controlled by optimizing processing parameters and process combinations. For example, during the processing of nickel-based superalloys, employing multidirectional die forging (at a temperature of 1050-1150°C with a deformation of 30%-50%) combined with isothermal rolling (at a temperature of 950-1050°C with a rolling speed of 0.5-1 m/min) can increase the yield from 60% to over 85%.
Q3: How to verify whether the material performance meets the standards?
A: Attention should be paid to key testing indicators. For instance, high-purity copper requires testing for electrical conductivity (≥100% IACS) and oxygen content (≤5ppm); alloys for aero-engines require testing for grain size (ASTM Grade 5-8) and room-temperature tensile strength (≥900MPa). Qinchuan's testing reports provide complete data and support third-party re-inspection by customers.

Real-world technical case: Everich New Materials helps a semiconductor enterprise break through production capacity bottleneck
A semiconductor enterprise suffered from a mere 75% yield rate of 4K display panels due to insufficient purity of high-purity molybdenum target materials (oxygen content of 8 ppm). Qingchuan reduced the oxygen content to 2 ppm through the combined VIM+EBM process, while optimizing grain control (average grain size ≤ 50 μm), thereby extending the target material's service life from 800 hours to 1200 hours. After the project's implementation, the enterprise's 4K panel yield rate increased to 92%, saving over 2 million yuan in annual costs.
