Aluminum-Magnesium-Manganese (Al-Mg-Mn) alloys are highly versatile and widely used due to their excellent combination of mechanical, corrosion-resistant, and fabrication properties. Here are the key advantages of Al-Mg-Mn alloys: 1. High Corrosion Resistance Marine Environments: These alloys have excellent resistance to corrosion in seawater and other harsh environments, making them suitable for shipbuilding, marine structures, and coastal applications. Atmospheric Conditions: Their corrosion resistance extends to industrial and urban atmospheres, which often have high levels of pollutants. 2. Good Strength-to-Weight Ratio Al-Mg-Mn alloys combine moderate strength with lightweight properties, making them ideal for transportation industries, such as automotive and aerospace, where weight savings improve fuel efficiency. 3. Enhanced Weldability These alloys exhibit good weldability, especially with proper techniques. This property is critical for applications requiring extensive welding, such as construction, pipelines, and storage tanks. 4. Excellent Formability They offer high ductility and can be easily rolled, extruded, or formed into complex shapes, which is valuable in manufacturing processes like sheet metal forming and extrusion. 5. High Resistance to Stress Corrosion Cracking (SCC) Al-Mg-Mn alloys have low susceptibility to SCC, ensuring long-term reliability in structurally demanding environments. 6. Non-Magnetic Properties Being non-magnetic, these alloys are suitable for applications where magnetic interference must be avoided, such as in electronics and sensitive instruments. 7. Recyclability Like other aluminum alloys, Al-Mg-Mn alloys are highly recyclable, reducing environmental impact and providing sustainability benefits. 8. Thermal Conductivity They offer decent thermal conductivity, which can be beneficial in applications where heat dissipation is required, such as heat exchangers and cooling systems. Common Applications: Marine Industry: Ship hulls, decks, and structural components. Automotive Sector: Body panels, structural reinforcements, and fuel tanks. Construction: Roofing, siding, and structural frameworks. Aerospace: Lightweight structural components. Storage Tanks: Cryogenic and chemical storage due to corrosion resistance. Overall, Al-Mg-Mn alloys are valued for their balance of strength, corrosion resistance, and ease of fabrication, making them a popular choice across various industries.

PE (Polyester) and PVDF (Polyvinylidene Fluoride) aluminum coils are widely used in construction and manufacturing for cladding, roofing, and other applications. Here’s a comparison based on various factors: 1. Coating Composition PE Coils (Polyester Coating): Coated with a polyester resin, providing a glossy finish and decent durability. Economical option.Basic resistance to UV rays, weather, and corrosion. PVDF Coils (Polyvinylidene Fluoride Coating): Coated with PVDF, which includes a blend of fluoropolymer resin and other compounds. Superior weather and UV resistance. Long-lasting durability in harsh environments. 2. Durability PE: Suitable for applications with moderate environmental exposure. Lifespan ranges from 5–10 years, depending on the environment. Prone to fading, chalking, and peeling in prolonged UV exposure. PVDF: Exceptional durability in extreme weather and industrial environments. Lifespan often exceeds 20 years. Highly resistant to fading, cracking, and corrosion. 3. Aesthetic Options PE: Available in a wide variety of colors and finishes, including glossy, matte, and metallic. More customizable for aesthetic purposes but with shorter-lasting vibrancy. PVDF: Offers fewer color options than PE but provides a consistently smooth and high-quality finish. Maintains color and gloss longer, especially in UV-intense regions. 4. Cost PE: More affordable due to simpler production processes and lower material costs. PVDF: More expensive, reflecting its higher performance and longevity. 5. Environmental Resistance PE: Moderate resistance to UV, heat, and chemical exposure. Better suited for interior or less demanding exterior applications. PVDF: Exceptional resistance to UV rays, acids, alkalis, and harsh weather conditions, making it ideal for industrial or marine environments. 6. Applications PE: Interiors and moderate climate exteriors. Suitable for signboards, interior walls, and light roofing. PVDF: High-end exteriors, including skyscrapers, industrial buildings, and areas with extreme climates. Used in roofing, curtain walls, and external cladding. 7. Maintenance PE: Requires more frequent cleaning and maintenance to maintain appearance and integrity. PVDF: Low maintenance due to its resistance to dirt, fading, and chalking. Summary Table Feature PE Coils PVDF Coils Durability Moderate High UV Resistance Limited Excellent Cost Lower Higher Lifespan 5–10 years 20+ years Applications Interior & mild exterior Demanding exterior Color Stability Moderate Excellent Conclusion Choose PE Aluminum Coils for cost-effective and short-to-medium term projects where aesthetics are important but durability is less critical. Opt for PVDF Aluminum Coils for long-term projects in harsh environments or where UV and weather resistance are key concerns.

Yantai Port Bauxite Client Symposium in 2024   Event to be held on July 26,2024 in Yantai Shandong     To further implement the strategic deployment of the Group's "building core competitive advantages" initiative and to create a world-class comprehensive supply chain service system centered on the port, the 2024 Yantai Port Bauxite Client Symposium was successfully held on July 26. Over 100 representatives from related units and logistics associations, railways, port authorities, and upstream and downstream enterprises in the alumina, mining, trading.       Qitai Aluminum has been invited to attend this conference. As a downstream factory in the aluminum industry, we also operate a bauxite business, reducing production costs from the source and providing our company with a significant competitive advantage. In 2022, we imported 120,000 tons of bauxite from Côte d'Ivoire. In 2023, we secured the sublease rights to three mines in Guinea, further enhancing our position in the bauxite industry and greatly supporting the cost reduction and efficiency improvement for Qitai Aluminum's operations.   Jiang Kai, Deputy Party Secretary and General Manager of Yantai Port, Zhao Weisu, Deputy Secretary General of the China Nonferrous Metals Industry Association, Li Leqiang, Director of the Freight Department of China Railway Jinan Group Co., Ltd., and Zhang Fangxin, General Manager of Chalco Qingdao International Trading Co., Ltd., attended and delivered speeches. The meeting was chaired by Wang Yipeng, Deputy General Manager and Chief Quality Officer of Yantai Port.   As a cornerstone of Yantai Port's operations and a critical source of cargo, the bauxite business is not only a strategic sector that Yantai Port has continually developed and prioritized but also a vital component in Yantai Port's efforts to build a world-class maritime port.   Shared aspirations overcome any distance. This symposium has created an excellent platform for integration, communication, and win-win cooperation. This enhanced cooperation will ensure the stable operation of the China-Africa bauxite logistics chain and support the high-quality development of the national aluminum industry.

On May 22, the delegation from International College of Zibo Vocational College visited Shandong Qitai Aluminum Technology Co., Ltd. for investigation and exchange, and signed the strategic framework agreement of school-enterprise cooperation.   Yu, general manager of Shandong Qitai Aluminum Technology Co., LTD., Manager Cui, head of Foreign Trade Department, Fa Qi, employee representative, Su Yuanbin, secretary of International College, Zhou Tao, director of International Cooperation Department of International College, and three international students of international College attended the meeting.           ▲ meeting  Before signing the contract, the international academy delegation was invited by the company to visit the enterprise factory.       ▲ Qi Tai Factory   ▲ Introduce the factory situation   ▲ explains the machine   ▲ Know the aluminum magnesium manganese plate   ▲ sample display     At the meeting, the general manager of Qitai Aluminum industry introduced the development process of the company and the strategic layout of "product-oriented, external development".
