Opening with the Industry's Technical Pain Points
In high-end fields such as aerospace, semiconductors, and new energy, the demand for high-purity metals and specialty alloys continues to grow, yet traditional manufacturing processes face three major challenges:
STEP 1: High difficulty in purity controlThe content of metallic impurities needs to be controlled at the ppm level or even the ppb level, which is difficult to achieve with traditional smelting processes;
STEP 2: Poor ingredient uniformityThe uneven distribution of multiple elements in special alloys easily leads to performance fluctuations, affecting product consistency;
STEP 3: Insufficient processing accuracyHigh-precision components have stringent requirements for dimensional tolerances, making it difficult for traditional processing equipment to achieve micron-level control.
Taking the semiconductor industry as an example, the purity of high-purity aluminum target materials must be ≥99.999%, and the grain size must be controlled below 50 μm. Traditional processes struggle to meet both criteria simultaneously, resulting in a product yield of less than 60%.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, specializes in the R&D and manufacturing of high-purity metals and special alloys, possessing the following technological advantages:
STEP 1: Configuration of advanced production linesThe company is equipped with high-end equipment such as vacuum induction melting furnaces and electron beam melting furnaces, enabling gradient control of metal purity ranging from 99.9% to 99.9999%. For instance, in the production of high-purity tungsten targets, by utilizing electron beam melting combined with zone refining technology, the impurity content is reduced to below 0.1 ppm, the grain size is controlled within 20 μm, and the yield is increased to 92%.
STEP 2: Precision Machining CapabilityIt is equipped with five-axis simultaneous machining centers, ultra-precision grinding machines, and other equipment, achieving a machining accuracy with part dimensional tolerances of ±1 μm and surface roughness Ra ≤ 0.05 μm. In the manufacturing of aero-engine blades, by optimizing tool paths through CNC programming, the machining cycle is reduced by 30% while meeting the fatigue resistance requirements of high-temperature alloys.
STEP 3: Full-process Inspection SystemEquipped with ICP-MS (Inductively Coupled Plasma Mass Spectrometry), X-ray diffractometers, and other equipment, it enables full-process testing of parameters such as material composition, grain structure, and residual stress. For example, in the production of special alloy bars, online spectral analysis is used to monitor composition fluctuations in real time, keeping deviations within ±0.02%.

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 target purity and material characteristics:
- 99.9%-99.99%Vacuum induction melting is adopted, which is cost-effective and efficient;
- 99.999%-99.9999%It requires the combination of electron beam melting and zone refining, but the equipment investment is substantial;
- Special forms (such as powder and wire)It is necessary to add gas atomization or wire drawing processes, and evaluate process compatibility.
Q2: How to control deformation in the processing of special alloys?
A: Optimization is required in three aspects:
- Tool SelectionUse carbide or ceramic cutting tools to reduce cutting heat;
- Cutting parametersThe spindle speed is controlled at 800-1200 rpm, with a feed rate of 0.05-0.1 mm/r;
- Cooling methodUtilize Minimum Quantity Lubrication (MQL) technology to reduce the temperature gradient of the workpiece.
Q3: How to verify whether the material performance meets the standards?
A: It requires multi-dimensional testing:
- Chemical compositionICP-MS is used to detect impurity content, with a deviation requirement of ≤0.01%;
- Mechanical propertiesThe universal testing machine is used to test tensile strength, and the data must comply with ASTM E8 standard;
- MicrostructureGrain morphology is observed by SEM, with an average grain size requiring ≤50 μm.
