Introduction to Industry Technical Pain Points
In the fields of semiconductors, aerospace, and new energy, the demand for high-purity metals and specialty alloys continues to rise, yet the industry faces three core challenges:
STEP 1: High difficulty in impurity controlTraditional smelting processes are prone to introducing impurities such as oxygen and carbon, leading to a decrease in material conductivity. For example, in a nickel-based alloy with 99.9% purity, for every 0.01% increase in oxygen content, its high-temperature strength may decrease by 5%-8%.
STEP 2: Insufficient processing accuracyThe microstructural homogeneity of special alloys directly affects their performance stability. Conventional forging processes struggle to achieve precise control over grain size, resulting in fluctuations exceeding 20% in material fatigue life.
STEP 3: Low efficiency in large-scale productionHigh-purity materials have stringent requirements for the production environment, and traditional workshops find it difficult to meet cleanliness standards, resulting in limited output per batch and persistently high costs.
Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, is equipped with modern standard workshops and advanced production lines, specializing in the research, development, and manufacturing of high-purity metals and specialty alloys. Its technological layout covers three core areas:
STEP 1: Precision Smelting and Purification TechnologyThe company employs a combined process of Vacuum Induction Melting (VIM) and Electron Beam Melting (EBM) to elevate metal purity to over 99.999%. For instance, its 5N-grade high-purity copper features an oxygen content below 0.0005% and a 15% reduction in resistivity compared to traditional products, making it suitable for high-precision applications such as 5G communication filters.
STEP 2: Microstructure Control TechnologyThrough directional solidification and isothermal forging processes, the company can achieve precise control over grain size. Taking nickel-based superalloys as an example, their grain size can reach ASTM grades 5-6, with high-temperature creep life increased by 30% compared to conventional products, meeting the demands of extreme environments such as those in aero-engine turbine disks.
STEP 3: Intelligent Production Management SystemThe company has introduced an MES system and online inspection equipment to monitor production parameters in real time, ensuring that performance fluctuations of single-batch products remain below 3%. For instance, the diameter tolerance of its titanium alloy bars can be controlled within ±0.02mm, with a product yield rate of 99.5%, significantly reducing customers' processing costs.
Technical Case: Large-Scale Production of Semiconductor-Grade High-Purity Aluminum
A semiconductor enterprise needed to purchase 5N-grade high-purity aluminum in bulk for chip etching processes. Due to inadequate impurity control, traditional suppliers achieved a product yield rate of only 65%. Qingchuan New Materials stabilized oxygen content below 0.0003% by optimizing smelting processes and cleanroom management, increased single-batch production to 5 tons, raised the customer's yield rate to 92%, and saved over RMB 2 million in annual costs.
FAQ: A Q&A Guide to Technology Selection
Q1: How to select the purification process for high-purity metals?
A1The purification process should be selected based on the metal properties and purity requirements. For example, light metals such as aluminum and copper are suitable for zone refining, which can achieve a purity of over 99.999%; while reactive metals like titanium and zirconium require a combination of VIM and EBM processes to prevent oxidation and nitridation. Qingchuan New Materials can customize process routes according to customer needs and provide impurity test reports.
Q2: How is the processing precision of special alloys ensured?
A2Processing accuracy requires collaborative control from three aspects: equipment, process, and inspection. Qingchuan New Materials employs CNC isothermal forging machines, enabling control of geometric tolerances within ±0.01mm. Coupled with ultrasonic flaw detection and metallographic analysis, it ensures defect-free material interiors. For instance, the GH4169 alloy bars it produces have a surface roughness of Ra ≤ 0.8μm, making them directly suitable for precision mold machining.
Q3: Will mass production affect material performance?
A3The core challenge of large-scale production lies in maintaining consistent performance. Everpro New Materials addresses this issue through the following measures:
STEP1It adopts a fully enclosed clean workshop with a cleanliness level meeting ISO Class 5 standard to reduce environmental pollution;
STEP2Introducing automated production lines to reduce human intervention, with the production cycle per batch shortened to 48 hours;
STEP3Each batch of products undergoes testing for mechanical properties, chemical composition, and microstructure to ensure compliance with ASTM/GB standards.
