Currently, the price of magnesium metal has continuously pulled back and is significantly lower than that of aluminum, once again highlighting its cost-effectiveness and functional value. Innovations in magnesium and magnesium alloy development are on the rise, with new application cases for magnesium alloys constantly emerging, heralding new opportunities for expanded applications, particularly in areas such as lightweight transportation, smart manufacturing, green construction, electronics and telecommunications, solid-state energy storage, and healthcare. As a lightweight structural and functional material, magnesium will play a crucial role in promoting green, low-carbon, and high-quality development, demonstrating greater potential. At this critical period, the 2025 Magnesium Industry Chain and Market Forum will continue to be held. We will fully leverage our platform advantages, summarize the experiences from previous events, increase the promotion of this event, enhance the participation of related industry chain enterprises, and strive for even greater success.

SMM and Shangmei Network cordially invite you to participate in the 2025 Magnesium Industry Chain and Market Forum, which will take place from March 31 to April 2, 2025. Leifu Technology (Guangdong) Co., Ltd. will attend this conference in full force. We will keep pace with the times, aim at our goals, and forge ahead with determination and courage!

Dongguan University of Technology - Leifu Chemical Industry-Academia-Research Base

Renowned Professor

Professor Jun Liang, Ph.D., Professor (Researcher) at Dongguan University of Technology, has been listed among the top 2% of global scientists in 2024 by Stanford University and Elsevier.

He mainly focuses on the design, preparation, performance evaluation, and damage/failure mechanism research of surface protection and functional integration materials for light metals such as aluminum, magnesium, and titanium. He has published over 100 papers in domestic and overseas academic journals, applied for more than 10 Chinese invention patents, and led over 20 projects including the National Natural Science Foundation, the Chinese Academy of Sciences' "Hundred Talents Program," the SASTIND's JPTT, and enterprise technical services.

Focusing on the key technical bottlenecks and issues in light metal surface engineering, he has developed a series of high-performance surface functional protective integrated materials and their preparation technologies and processes, achieving engineering applications in aerospace, 3C, and other fields, generating significant economic and social benefits.

He also serves as a member of the Youth Committee and the Erosion and Protection Technology Special Committee of the Chinese Society for Corrosion and Protection, a council member of the Heat Treatment Branch of the Chinese Mechanical Engineering Society, and an editorial board member of Materials and Tribology, as well as a technical advisor to Leifu Technology (Guangdong) Co., Ltd.

With advanced formulas, imported raw materials, and strict quality control, the company has overcome the technical challenges of phosphorus-free, nitrogen-free, nickel-free, and manganese-free processes. The neutral salt spray performance of its phosphorus-free magnesium alloy products stabilizes at above 9 levels for 48 hours, with a resistance of less than 0.1Ω, helping the industry move towards a new era of green and efficient development.

Product Performance Advantages

Successful Cases

The assessment of magnesium alloy surface treatment results is primarily conducted through corrosion resistance, resistance, appearance, paint adhesion, and coating hardness.

1. Customer Salt Spray Status

The customer's magnesium alloy products failed the post-formation test, notably showing poor salt spray performance, failing to pass the 72-hour neutral salt spray test.

2. Solution Process

The Leifu team conducted multiple rounds of comparative studies, weighing the pros and cons from various dimensions, and ultimately optimized the formula and adjusted the solution ratio to find the best solution.

3. Salt Spray Results

The cross-cut test reached 5B.

High Resistance Adverse Effects

The effects of high resistance after magnesium alloy formation:

1. Poor Conductivity: For some components of electronic devices (electrode materials, electromagnetic shielding enclosures), high resistance hinders electron transmission. In electrode applications, it may lead to signal transmission delays, signal attenuation, and other issues, affecting the overall performance of the device;

2. Reduced Electromagnetic Shielding Efficiency: With increased resistance, the reflection and absorption capabilities of electromagnetic waves weaken, making it difficult to effectively prevent external electromagnetic waves from entering the device and to stop internal electromagnetic waves from leaking out, thus reducing electromagnetic shielding efficiency;

Processing Steps

Facing challenging problems, the Leifu team analyzed the material properties, process parameters, and operational procedures from multiple dimensions. After numerous rounds of comparative studies, balancing factors such as cost, efficiency, and feasibility, they finally distilled a practical and effective solution.
