Opening Remarks on Industry Technical Pain Points
STEP 1: Challenge in purity control. Traditional smelting processes struggle to completely remove impurity elements, resulting in high-purity metals with purity levels below 99.999% (5N grade), which fails to meet the stringent purity requirements for semiconductor wafer carriers. STEP 2: Poor compositional uniformity. The uneven distribution of trace elements in specialty alloys can easily lead to localized performance degradation. For instance, if the compositional deviation in nickel-based alloys used for aerospace engine blades exceeds 0.05%, it may reduce high-temperature creep life by over 30%. STEP 3: Low process stability. Temperature fluctuations exceeding ±5°C or deviations in atmosphere control during production can significantly affect the material's crystalline structure, resulting in a product yield of less than 60%.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in Zhengzhou High-Tech Industrial Development Zone, boasting modern standard workshops and internationally advanced production lines for specialty alloys and high-purity materials. Its core technological布局 covers three major directions:
STEP 1: Vacuum induction melting technology. Through a multi-stage vacuum system (ultimate vacuum degree ≤ 1×10⁻⁴ Pa) and an electromagnetic stirring device, it achieves a metal liquid composition uniformity of ≤ 0.02% and a purity of 6N grade (99.9999%), suitable for the preparation of semiconductor-grade refractory metals such as tungsten and molybdenum.
STEP 2: Directional Solidification Control Technology. By employing a water-cooled copper mold and a gradient cooling system, the solidification rate is controlled within the range of 0.1-10 mm/min, refining the grain size of nickel-based alloys to below ASTM Grade 5 and enhancing high-temperature strength by 25%.
STEP 3: Intelligent Inspection System. Equipped with direct-reading spectrometers (detection limit of 0.0001%) and electron probe microanalyzers (resolution of 0.1 μm), among other equipment, to achieve full-process quality traceability from raw materials to finished products.
Practical case: An aero-engine enterprise adopted GH4169 alloy bars provided by Ever Power. After a 1000-hour high-temperature endurance test, the creep rate decreased by 40% compared to traditional materials, meeting the requirements for long-life design.For more information, please visit the official website.

FAQ: A Guide to Technical Selection with Q&A Format
Q1: How to select the preparation process for high-purity metals?
A: It needs to be determined based on material properties and purity requirements. For instance, for metals like tungsten and molybdenum with melting points exceeding 2000℃, electron beam melting (with purity up to 6N) or chemical vapor deposition (CVD) technology is preferred; for metals prone to oxidation, such as titanium and aluminum, vacuum melting under the protection of an inert atmosphere is required. Qinchuan's vacuum induction melting furnace is equipped with a multi-layer gas purification system that can control oxygen content below 5ppm.
Q2: How to test the composition uniformity of special alloys?
A: Key inspection indicators include deviations in chemical composition, uniformity of microstructure, and consistency of physical properties. Qingchuan employs direct-reading spectrometers for rapid composition analysis (inspection time ≤ 2 minutes) and utilizes Electron Backscatter Diffraction (EBSD) technology to evaluate grain orientation distribution, ensuring alloy composition deviations ≤ 0.01%.
Q3: What factors affect process stability?
A: It mainly involves temperature control accuracy, atmosphere purity, and equipment vibration level. The Qingchuan production line is equipped with a PID intelligent temperature control system (temperature fluctuation ≤ ±2°C), a molecular sieve adsorption device (gas dew point ≤ -60°C), and an active vibration damping base (vibration amplitude ≤ 0.01mm), elevating process stability to an industry-leading level.For more information, please visit the official website.
