Introduction: Why have high-purity metal materials become pivotal in the industry?
High-purity metallic materials (such as titanium, zirconium, and nickel-based alloys with a purity of 99.999%) are core raw materials in aerospace, semiconductors, new energy, and other fields, with their purity directly influencing product performance and lifespan. However, traditional preparation technologies face challenges such as difficulty in impurity control, high energy consumption, and poor process stability, leading to long-term industry reliance on imports. Qingchuan New Materials (Zhengzhou) Co., Ltd. has achieved large-scale production of high-purity metallic materials through its independently developed "multi-stage vacuum melting-directional solidification" technology, with purity indicators reaching internationally advanced levels. This article will analyze its technological breakthrough path from dimensions such as technical principles, corporate capabilities, and application cases.

Opening on Industry Technical Pain Points: Three Major Bottlenecks of Traditional Preparation Technologies
STEP 1: Difficulty in impurity control. Traditional smelting processes (such as electric arc furnaces and induction furnaces) are prone to introducing impurities such as oxygen, nitrogen, and carbon, making it difficult to achieve a purity exceeding 99.9%. For example, a semiconductor company once experienced a 15% decline in chip yield due to insufficient purity (99.8%) of titanium target materials.
STEP 2: High energy consumption and cost. Vacuum induction melting requires multiple remelting processes, with energy consumption per ton exceeding 5,000 kWh, and equipment depreciation costs accounting for 30%.
STEP 3: Poor process stability. Traditional directional solidification technology is prone to grain boundary segregation due to imprecise control of temperature gradients, resulting in fluctuations exceeding 20% in the mechanical properties of the material.

Introduction to the Company's Technological Strength: Innovative Solutions of Everich New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in Zhengzhou High-Tech Industrial Development Zone, boasting modern standard workshops and internationally leading production lines for special alloys. Its core advantages are manifested in three aspects:
STEP 1: Multi-stage vacuum smelting technology. Through the three-stage linkage of "primary vacuum induction melting + intermediate electron beam melting + advanced plasma arc melting," the impurity content is reduced to below 0.001%. For example, the TA15 titanium alloy produced by this method achieves a purity of 99.995% with an oxygen content ≤ 80 ppm, far exceeding the ASTM B348 standard.
STEP 2: Directional solidification with dynamic temperature gradient control. By employing infrared temperature measurement and PID algorithm, precise regulation of temperature gradient (±2℃/cm) is achieved, grain size uniformity is improved by 40%, and tensile strength reaches over 1200 MPa.
STEP 3: Full-process quality inspection system. Equipped with devices such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and XRD (X-Ray Diffraction), it can detect 56 types of elemental impurities with a detection precision reaching the ppb level. In 2023, the first-pass yield rate of its products reached 99.2%, with a customer complaint rate below 0.5%.
Example of technical parameters:
- Smelting temperature: 1600-1800℃ (adjustable)
- Vacuum degree: ≤5×10⁻³ Pa
- Directional solidification rate: 0.5-5 mm/min
- Applicable materials: Titanium, zirconium, nickel-based alloys, cobalt-based alloys, etc.

FAQ Q&A Technical Selection Guide
Q1: How to select a supplier of high-purity metal materials?
A: We need to focus on three key points:
- Purity test report: Require suppliers to provide ppb-level test data from a third-party institution (such as SGS);
- Process stability: Evaluate the temperature control accuracy of its directional solidification equipment (recommended ≤ ±3℃/cm);
- Case Experience: Priority is given to enterprises with a supply track record in the aerospace or semiconductor sectors. For instance, Qingchuan New Materials once customized a zirconium alloy with 99.999% purity for an aerospace enterprise, which was used in rocket engine nozzles. After 10 thermal tests, the material's lifespan was proven to have increased threefold.
Q2: How can the cost composition of high-purity metal materials be optimized?
A: Cost optimization requires efforts in both process and scale:
- Process optimization: Adopting multi-stage smelting instead of single remelting can reduce energy consumption by over 30%;
- Economies of scale: When the production capacity of a single production line reaches 500 tons/year, unit costs can decrease by 25%. Through modular production line design, Qingchuan New Materials has achieved flexible capacity expansion from 100 tons/year to 1,000 tons/year, allowing customers to place orders flexibly according to their needs.
Q3: How can pollution be avoided during material processing?
A: It is necessary to strictly control the processing environment and tools:
- Environmental requirements: The cleanroom must meet ISO Class 5 (Class 100) standards;
- Tool material: Select the same or purer material as the base material (e.g., using high-purity titanium for processing titanium alloys);
- Operational norms: Avoid direct human contact and use automated robotic arms for handling. Qingchuan New Materials provides customers with an integrated "materials + processing" service, with its processing workshop equipped with five-axis simultaneous CNC machine tools capable of achieving a processing precision of ±0.005mm.
