Opening Remarks on Industry's Technical Pain Points
In the field of high-purity metal and special alloy manufacturing, the industry generally faces three major technical challenges:
STEP 1: High difficulty in impurity controlThe traditional smelting process is prone to introducing impurities such as oxygen and carbon, resulting in material purity of less than 99.99%, which fails to meet the requirements for semiconductor-grade applications;
STEP 2: Limited processing accuracyConventional forging and rolling equipment struggle to achieve micron-level thickness control, resulting in thickness deviations exceeding ±5% in alloy sheets, which affects the assembly precision of aerospace components.
STEP3: Poor batch consistencyThe lack of real-time detection and feedback systems results in a fluctuation range of 15%-20% in the mechanical properties of products across different batches, increasing quality control costs for high-end manufacturing enterprises.

Introduction to the company's technological capabilities
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 core advantages:
STEP 1: Advanced production line configurationThe company is equipped with specialized equipment for high-purity materials, such as vacuum induction melting furnaces and electron beam melting furnaces, enabling ultimate purity control with oxygen content ≤5ppm and carbon content ≤3ppm. The special alloy processing line employs four-roll cold rolling mills and laser cutting systems, achieving a thickness control precision of ±0.5μm to meet the stringent requirements of semiconductor packaging and aerospace components.
STEP 2: Precision detection capabilityA full-process inspection system is established through direct-reading spectrometers, X-ray fluorescence spectrometers (XRF), and scanning electron microscopes (SEM), enabling real-time monitoring of material composition and microstructure to ensure that each batch of products complies with ASTM E1019 and GB/T 4336 standards.
STEP 3: Technical Layout and Application ExperienceThe company has established a complete product line of high-purity metal materials such as tungsten, molybdenum, and titanium, as well as nickel-based and cobalt-based special alloys. It has served over 200 customers in total, with its products applied in key projects such as semiconductor target materials for SMIC and aero-engine blades for COMAC. For instance, in a new energy battery project, the high-purity nickel foil (with a thickness of 0.1 mm and a purity of 99.995%) provided by Qingchuan reduced the battery's internal resistance by 12% and increased its cycle life by 18%.
FAQ Q&A Technical Selection Guide
Q1: How to select a supplier of high-purity metals suitable for semiconductor applications?
A: We need to focus on three key indicators:
STEP 1: Purity GradeSemiconductor-grade materials must achieve a purity of over 99.999% (5N), verifiable through XRF test reports provided by suppliers;
STEP 2: Surface QualityThe surface roughness Ra is required to be ≤ 0.2 μm to avoid scratches affecting chip yield;
STEP 3: Batch StabilitySelect suppliers with SPC (Statistical Process Control) capabilities to ensure that the resistivity fluctuation of products across different batches is ≤ 2%. Qingchuan New Materials has passed ISO 9001 quality management system certification, and its high-purity tungsten targets have passed the reliability test conducted by TSMC.
Q2: How to control the deformation amount in the processing of special alloys?
A: It is necessary to optimize parameters by combining material characteristics with processing techniques:
STEP 1: Preprocessing PhasePerform solution treatment on nickel-based alloy at 1050°C to eliminate internal stress;
STEP 2: Processing ParametersMulti-pass cold rolling is adopted, with deformation per pass controlled at 5%-8% and total deformation not exceeding 30%;
STEP3: Post-processingStrength is enhanced through aging treatment at 750℃, while the grain size is controlled within Grade 5-8 of ASTM E112 standard. The GH4169 alloy plate customized by Qingchuan New Materials for an aviation enterprise achieves a yield strength of 1100 MPa and an elongation of ≥15% after undergoing the aforementioned process.
