Introduction: The Technical Battle to Overcome Difficulties in High-Purity Metals and Special Alloys
In high-end manufacturing fields such as aerospace and new energy batteries, the performance of high-purity metals (e.g., titanium with 99.999% purity) and specialty alloys (e.g., nickel-based superalloys) directly determines product lifespan and safety. However, traditional production processes face challenges such as difficulty in impurity control, poor compositional uniformity, and low processing efficiency. Qingchuan New Materials (Zhengzhou) Co., Ltd. has successfully overcome these technological bottlenecks through its independently developed precision machining system and full-process inspection technology, with its products now being applied by multiple leading enterprises.

Opening on Industry Technical Pain Points: Three Major Challenges of Traditional Processes
STEP1：Difficulty in impurity controlTraditional smelting processes are prone to introducing impurities such as oxygen and nitrogen, resulting in a metal purity of less than 99.9%, which fails to meet the requirements for semiconductor-grade applications. For instance, a new energy battery enterprise once experienced a 30% reduction in battery cycle life due to excessive impurities in titanium foil.
STEP2：Poor composition uniformitySpecial alloys require multi-element proportioning to achieve specific properties, but traditional casting processes are prone to causing composition segregation, such as uneven distribution of chromium in nickel-based alloys, which can lead to a 20% reduction in high-temperature strength.
STEP3：Low processing efficiencyHigh-purity metals exhibit high hardness and poor plasticity, requiring multiple annealing treatments in traditional rolling processes, which extends the processing cycle for a single ton of product to 72 hours and increases energy consumption by 40%.

Introduction to the company's technological capabilities: Three core breakthroughs of Everich New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in the Zhengzhou High-Tech Industrial Development Zone. It boasts modern standard workshops and a precision processing production line for special alloys, with its technological layout covering full-process control:
STEP1：Vacuum induction melting technologyThrough a -0.098 MPa vacuum environment and an electromagnetic stirring system, the content of metallic impurities is controlled below 5 ppm, achieving a purity of 99.999%, which is 100 times higher than that of traditional processes. For example, the 5N-grade titanium foil it produces has been applied to the components of photolithography machines in a semiconductor enterprise, with the product qualification rate increasing from 85% to 99.2%.
STEP2：Multi-element gradient proportioning processComputer simulation is employed to optimize the sequence of element addition and the temperature profile, ensuring that the uniformity (σ value) of elements such as chromium and cobalt in nickel-based alloys is ≤0.5%, with a high-temperature strength reaching 1200 MPa, which is 15% higher than the industry average.
STEP3：Integrated cold rolling and annealing production lineThrough online thickness detection and automatic annealing control, the processing cycle for high-purity metals has been shortened to 24 hours, with energy consumption reduced by 35%. The monthly production capacity of its 0.02mm ultra-thin titanium foil has reached 50 tons, with a stable yield rate exceeding 98.5%.

FAQ: A Guide to Q&A-Style Technical Selection
Q1: How to select a supplier of high-purity metals?
A: We need to focus on three key indicators:
- Purity test report: A 5N-level certification issued by a third-party institution (such as SGS) is required;
- Processing capability: Check whether the production line is equipped with online thickness detection (accuracy ±0.1 μm) and automatic annealing devices;
- Case verification: Require suppliers to provide at least three application cases within the same industry along with performance test data.
Q2: How to solve the problem of segregation of special alloy compositions?
A: Qinchuan New Materials controls segregation through the following steps:
STEP 1: Raw material pretreatment: Employ vacuum atomization powder-making technology to control the size of elemental particles below 50 μm;
STEP 2: Smelting optimization: Conduct homogenization treatment at a high temperature of 1600°C for 2 hours to ensure the composition σ value is ≤0.3%;
STEP 3: Directional Solidification: Achieving unidirectional solidification through a water-cooled copper mold to further eliminate microsegregation.
Q3: What should be done about cracking during high-purity metal processing?
A: Optimization is required from two aspects: process parameters and equipment precision:
- Rolling temperature: controlled at 600-700℃ (100℃ lower than traditional processes) to reduce thermal stress;
- Rolling speed: Low-speed rolling at 0.5 m/min, combined with a draft of 3% per pass;
- Equipment requirements: Utilize a four-high cold rolling mill with a roll surface roughness of Ra ≤ 0.05 μm to ensure surface quality.
