Opening with the Industry's Technical Pain Points
The traditional metal processing field has long faced three major challenges:
STEP 1 Challenges in Purity ControlIt is difficult to control the impurity content below the ppm level using conventional smelting processes, resulting in materials being prone to failure under high-temperature and corrosive environments. For example, if the purity of the nickel-based alloy in turbine blades used in the aerospace field is insufficient, their heat resistance will decrease by more than 30%.
STEP2 Insufficient ingredient uniformitySpecial alloys require specific performance achieved through multi-element proportioning, but traditional smelting techniques are prone to causing composition segregation, affecting product consistency. According to statistics, the scrap rate due to uneven composition reaches as high as 15% in small and medium-sized enterprises.
STEP 3 Limited processing accuracyCutting processing of high-hardness alloys requires tolerance at the micrometer (μm) level, which is difficult to achieve with stable control using ordinary equipment, resulting in excessive surface roughness of the product and affecting its sealing performance.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd. has addressed industry challenges through three major technological strategies:
STEP 1 Vacuum induction melting technologyThe company has introduced a German ALD vacuum induction furnace, which can complete smelting under a vacuum environment of 10⁻³ Pa and control the content of gaseous impurities such as oxygen and nitrogen within 5 ppm. This equipment supports 200 kg-level smelting with a temperature control accuracy of ±2℃, ensuring composition uniformity of ≥99.9%.
STEP2 Precision Forging ProcessA 6,000-ton hydraulic press and a closed-loop control system are employed to achieve dimensional tolerances of ≤0.05 mm for alloy forgings. Taking a certain type of aviation connector as an example, the surface roughness (Ra) of its forgings is ≤0.4 μm, representing a twofold improvement over traditional processes.
STEP3 Full-process Inspection SystemEquipped with direct-reading spectrometers, electron microprobes, and other equipment, it enables comprehensive dimensional testing of materials, ranging from chemical composition to microstructure. For example, EBSD technology is used to analyze grain orientation, ensuring product performance complies with ASTM E112 standards.

Real-world case: A new energy vehicle battery manufacturer required customized high-purity copper busbars (purity ≥ 99.99%). Everrich reduced the impurity content from 50 ppm to 8 ppm by optimizing the electrolytic refining process, and simultaneously achieved joint-free production of single busbars up to 1,200 m in length using continuous extrusion technology, helping the customer reduce connection losses by 12%.

FAQ: A Guide to Q&A Technical Selection
Q1: How to select a suitable supplier of high-purity metals?
A: Three major indicators require key assessment:
- Detection capability: Whether it is equipped with high-precision analytical equipment such as ICP-MS, and whether the detection limit reaches the ppb level;
- Process stability: Review the data on composition fluctuations between batches over the past three years, with the standard deviation being ≤ 0.05%;
- Customization capability: Whether parameters such as grain size and hardness can be adjusted according to requirements, and whether the minimum order quantity is flexible.
Q2: How to control the deformation amount in the processing of special alloys?
A: It is necessary to follow the operational procedures of STEP 1-3:
- STEP 1 Preprocessing: Reduce material hardness to HB ≤ 180 through spheroidizing annealing to improve machinability;
- STEP 2 Parameter optimization: Use high-speed steel cutting tools, with cutting speed controlled at 80-120 m/min and feed rate at 0.1-0.15 mm/r;
- STEP 3 Cooling Control: Use emulsion for cooling with a flow rate ≥ 15 L/min to prevent work hardening.
Q3: How to verify whether the material performance meets the standards?
A: The following testing indicators can be referred to:
- Chemical composition: Utilizing XRF fluorescence spectrometer with an error range ≤ 0.01%;
- Mechanical properties: Tensile strength tested by a tensile testing machine, with data fluctuation ≤ 5%;
- Corrosion resistance: A 480-hour neutral salt spray test is conducted in a salt spray test chamber, with a surface corrosion rate ≤ 0.1 g/m²·h.
