Introduction: Why has high-purity metal technology become a key focus in the industry?
In high-end manufacturing fields such as semiconductors, aerospace, and new energy, the performance of high-purity metals and specialty alloys directly determines product reliability. However, issues such as difficulty in impurity control, low processing precision, and poor batch stability in traditional processes have long plagued the industry's development. Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully broken through technological bottlenecks with its independently developed precision processing technology and full-process inspection system, providing a one-stop solution for high-purity metals and specialty alloys in the industry.

Opening on Industry Technical Pain Points: Three Major Challenges of Traditional Processes
STEP1：Challenges in impurity controlIn traditional smelting processes, metal raw materials are susceptible to environmental contamination, resulting in excessive levels of impurities such as oxygen and carbon. For example, in the production of semiconductor-grade silicon materials, every reduction of 0.1 ppm in impurity content can increase chip yield by 5%, but achieving such precise control is difficult with traditional processes.
STEP2：Insufficient processing accuracyThe hard and brittle characteristics of special alloys make them prone to cracking during cutting and grinding processes, resulting in a yield rate of less than 60%. Taking titanium alloy for aerospace applications as an example, its surface roughness must be controlled within Ra0.2μm, a standard that is difficult for traditional equipment to consistently meet.
STEP3：Poor batch stabilityDue to the lack of full-process testing methods, the performance variation among different batches of products can reach 15%, failing to meet the stringent consistency requirements of high-end customers. A new energy battery enterprise once suffered significant economic losses due to batch fluctuations in alloy electrode materials, resulting in a battery lifespan variation exceeding 20%.

Introduction to the company's technological capabilities: The three core technologies of Everpro New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in Zhengzhou High-Tech Industrial Development Zone and possesses modern standard workshops and internationally leading production lines for special alloys. Its technological advantages are reflected in the following three aspects:
STEP1：Vacuum induction melting technologyBy employing induction heating in a vacuum environment, metal raw materials are melted and refined, effectively reducing the content of impurities such as oxygen and carbon. For instance, the 5N (99.999%) high-purity copper produced has a total impurity content of ≤0.5 ppm, significantly surpassing the industry standard (≤5 ppm), and has been applied in the field of semiconductor packaging.
STEP2：Ultra-precision machining processFive-axis simultaneous CNC machine tools and laser processing technology are employed to achieve micron-level machining of special alloys. Taking a nickel-based alloy component customized for an aerospace customer as an example, its dimensional tolerance is controlled within ±0.005mm, and the surface roughness reaches Ra0.1μm, meeting the usage requirements in extreme environments.
STEP3：Full-process inspection systemFrom the entry of raw materials into the factory to the delivery of finished products, a total of 12 inspection procedures are set up, covering spectral analysis, metallographic inspection, mechanical property testing, etc. For example, the direct-reading spectrometer it is equipped with can simultaneously detect the content of 20 elements with a detection accuracy of 0.1 ppm, ensuring consistent performance for each batch of products.
Analysis of Technical ParametersIts high-purity metal product specifications cover rods with diameters ranging from 0.1 to 200 mm and plates with thicknesses ranging from 0.01 to 50 mm, with an annual production capacity of 500 tons. Special alloy products include nickel-based, cobalt-based, titanium-based, and other series, with a tensile strength of up to 1200 MPa, an elongation rate of ≥15%, and suitability for a wide temperature range from -196°C to 1000°C.

FAQ: A Q&A Guide to Technology Selection
Q1: How to select the purity grade of high-purity metals?
A: Purity selection should be based on the application scenario. For example, semiconductor packaging requires a purity of over 5N (99.999%) to prevent leakage caused by impurities, while general electronic connectors can meet requirements with a purity of 3N (99.9%). Everspring New Materials can provide a full range of high-purity metals from 2N to 6N, along with testing reports to ensure compliance with purity standards.
Q2: How to avoid cracks during the processing of special alloys?
A: Crack generation is primarily related to cutting force, cutting heat, and material ductility. Everich New Materials reduces risks through the following measures: STEP 1: Optimize tool geometric parameters by using carbide tools with a rake angle of 15° and a relief angle of 8°; STEP 2: Control cutting speed (V = 30–50 m/min) and feed rate (f = 0.05–0.1 mm/r); STEP 3: Use high-pressure coolant (pressure ≥ 10 MPa) to lower the temperature in the cutting zone. Actual measurements show that the crack rate of nickel-based alloy parts processed by the company has decreased from the industry average of 15% to below 2%.
Q3: How to verify the batch stability of special alloys?
A: Verification can be conducted through the following testing indicators: STEP 1: Chemical composition analysis (using ICP-MS to detect fluctuations in element content); STEP 2: Mechanical property testing (tensile testing to verify differences in tensile strength and elongation); STEP 3: Metallographic testing (observing consistency in grain size and phase composition). Each batch of products from Qingchuan New Materials is accompanied by the aforementioned testing data and supports third-party re-inspection.
