High-Strength Aluminum Alloy Die Casting Parts with High-Thermal-Conductivity

Product description:

• High-Strength Aluminum Alloy: The Al-Si-Mg-Cu series alloy developed specifically for load-bearing scenarios, after T7 heat treatment, has a tensile strength exceeding 580MPa, a yield strength of 520MPa, and an elongation at break maintained above 8%. In high-frequency stress-bearing components such as automobile chassis crossbeams and construction machinery arms, it can replace traditional steel to achieve a 40% weight reduction while improving fatigue resistance by 30%.

• High-Thermal-Conductivity Aluminum Alloy: The Al-Si series alloy with optimized silicon content has a thermal conductivity increased to 230W/(m·K), far exceeding that of ordinary die-cast aluminum (160W/(m·K)). Combined with the integrally formed heat dissipation pattern design, it can reduce the temperature of core components by 8-12℃ in new energy vehicle motor controllers and 5G base station power amplifier modules, extending the service life of equipment.

• Corrosion-Resistant Magnesium Alloy: The AZ81M magnesium alloy improved by adding rare earth elements can pass a 120-hour salt spray test without corrosion, while maintaining the low-density advantage of 1.85g/cm³. It meets the dual needs of "lightweight + weather resistance" in scenarios sensitive to weight and requiring outdoor use, such as laptop hinges and UAV fuselages.

• Ultra-High-Pressure Molding Technology: Adopting an 8,000-ton intelligent die-casting unit with a maximum clamping force of 80,000kN, it can integrally form large structural parts (such as new energy vehicle rear floor panels) with a length exceeding 2 meters in one go. The part integration rate is increased by 90%, and more than 150 welding points are reduced, significantly lowering assembly errors and potential failure risks.

• Closed-Loop Quality Control: Introducing an AI visual inspection system with an identification accuracy of 0.02mm for surface defects of castings (such as pinholes and cracks). Equipped with online mechanical property testing equipment, tensile strength and hardness are sampled and tested every 10 minutes, ensuring that the batch performance fluctuation is ≤5% and the yield rate is stably maintained at 99.9%.

• Green Surface Treatment: Adopting environmentally friendly processes such as chromium-free passivation and water-based electrophoresis, reducing VOC emissions by 60%. At the same time, it achieves a wear-resistant coating with a surface hardness of HRC45, which can withstand 5,000 friction cycles without obvious scratches in high-frequency contact scenarios such as automobile wheels and outdoor lamp housings.

• Performance Value: In extreme environments ranging from -60℃ to 180℃, the dimensional stability error is <0.05%, meeting the strict requirements of aerospace and polar scientific research equipment; the impact resistance reaches 120kJ/m², far exceeding the industry average (80kJ/m²), ensuring structural safety during automobile collisions.

• Cost Value: Integral molding reduces the number of parts by 50% and shortens the production cycle by 30%. Taking the new energy vehicle battery tray as an example, compared with the traditional stamping and welding process, the cost per set is reduced by 28%, and the aluminum alloy material recovery rate reaches 98%, complying with low-carbon production requirements.

• Design Value: It supports the molding of complex inner cavities, thin walls (minimum thickness of 0.25mm) and special-shaped structures, enabling design schemes that cannot be achieved by traditional processes. For example, the integrated middle frame of electronic equipment not only simplifies assembly but also improves the overall structural strength.

• New Energy Vehicles: Providing core components such as rear floor assemblies, battery pack upper covers and motor housings. Among them, the rear floor assembly is integrally formed using an 8,000-ton die-casting machine, with a weight of only 35kg, achieving a 55% weight reduction compared with traditional steel structures and increasing the body torsional stiffness by 25%. It has been matched with mass-produced models of automakers such as NIO and XPeng.

• High-End Electronics: Supplying integrated middle frames and heat dissipation components for laptops and smart wearable devices. For example, the middle frame of a certain brand of ultra-thin laptop is integrally formed using high-thermal-conductivity aluminum alloy, with a thickness of only 2.5mm, reducing weight by 18% while increasing heat dissipation efficiency by 22%.

• Intelligent Equipment: Adapting to high-precision components such as industrial robot joints and UAV fuselages. The industrial robot joint components are made of high-strength aluminum alloy with a precision of ±0.02mm, which can withstand 10,000 hours of continuous operation without failure, improving the operational stability of equipment.

• Clean Energy: Producing solar photovoltaic brackets and wind power equipment nacelle components. The photovoltaic brackets are made of corrosion-resistant aluminum alloy, showing no obvious corrosion after 10 years of use in coastal areas. Compared with steel brackets, they reduce weight by 60%, lowering installation and transportation costs.

• Early R&D Stage: Equipped with an R&D team of more than 100 professionals, providing DFM (Design for Manufacturability) services. The product structure is optimized through Magma simulation software, reducing mold development risks and shortening the R&D cycle by 2-3 months.

• Production and Delivery: Establishing 3 intelligent production bases with more than 50 high-end die-casting equipment, achieving a daily production capacity of 15,000 pieces. It supports fast delivery of small-batch orders (starting from 100 pieces) and large-batch orders, with emergency orders responding within 72 hours.

• After-Sales Support: Providing a 2-year warranty service and establishing 10 after-sales service outlets nationwide, with 24-hour technical response. Regular on-site inspections are conducted to collect customer usage data, continuously optimizing product performance and providing customers with full-lifecycle technical support.
