Opening on the Pain Points of Industry Technology
Traditional special alloy production faces two core challenges: first, difficulty in purity control, as excessive impurity content can easily lead to material embrittlement or reduced corrosion resistance; second, insufficient performance stability, with mechanical strength differences of over 15% among different batches of products. Taking the aerospace sector as an example, micro-cracks emerged in the blades of a certain engine model due to insufficient alloy purity under high-temperature conditions, resulting in a 30% reduction in the overall lifespan of the engine. Qingchuan New Materials has reduced impurity content to below 0.005% by introducing multi-stage vacuum melting technology and an intelligent composition analysis system, while narrowing the performance fluctuation range of products to ±2% through dynamic heat treatment processes, significantly enhancing material reliability.

Introduction to the company's technological strength
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in Zhengzhou High-Tech Industrial Development Zone, equipped with modern standard workshops and three fully automated production lines, with core equipment including:
STEP 1: Multistage Vacuum Melting Furnace
It adopts a five-stage vacuum environment design, with a melting temperature reaching 2000℃. Through inert gas protection and electromagnetic stirring technology, it achieves a 40% improvement in the uniformity of molten metal and a 99.5% efficiency in impurity removal.

FAQ Q&A Technical Selection Guide
Q1: How to select special alloys suitable for high-temperature environments?
A: We need to focus on three parameters:
- Melting point: Must be more than 200°C higher than the operating environment temperature (e.g., nickel-based alloy with a melting point of 1400°C is suitable for a 1200°C environment);
- Coefficient of thermal expansion: It should match with the complementary materials (e.g., a certain model of alloy has a linear expansion coefficient of 12.5×10⁻⁶/℃, demonstrating excellent compatibility with ceramic substrates);
- Antioxidation: Verified through salt spray test (Everich products have passed a 1000-hour neutral salt spray test with a corrosion rate ≤ 0.01 mm/year).
Q2: Is low-volume custom production feasible?
A: Qingchuan supports flexible production with a minimum order quantity of 10kg. By utilizing modular production lines and rapid mold-changing technology, it has shortened the delivery cycle to 7 days, representing a 40% improvement over the industry average.
Q3: How to verify product performance?
A: Provide a complete set of test reports, including:
- Chemical composition analysis (in compliance with GB/T 15077 standard);
- Mechanical property testing (tensile strength ≥ 950 MPa, yield strength ≥ 800 MPa);
- Metallographic structure inspection (grain size grade 6-8).
