Decarbonization, Thermal Control, and Advanced Metallurgy for Next-Generation Enclosures
Historically, basic structural profiles relied almost entirely on standard 6063 alloys. Today, Aolijie's metallurgical roadmap integrates ultra-purified silicon-magnesium structural profiles with high-copper and zinc formulations (e.g., 6061-T6, 6082-T6, and specialized 7xxx series) to enhance yield strengths beyond 310 MPa, meeting harsh aerospace and defense criteria.
With power densities in electronic housings continuously increasing, we are expanding our custom extrusion capabilities for complex internal micro-fin arrays. This includes multi-port internal liquid channels designed for direct coolant flow, eliminating the thermal interface resistance found in assembled thermal systems.
Allying with green smelting processes, Aolijie commits to using low-carbon primary aluminum billets sourced via renewable hydroelectric smelters. Our goal is to reduce the embodied carbon footprint of our finished profiles by 40% before 2030, aligning with EU and North American ESG import standards.
To support design flexibility, Aolijie's technology roadmap focuses on advancing co-extrusion methods and integrated metal-to-plastic thermal breaks. These hybrid profiles provide structural strength while ensuring galvanic isolation and thermal insulation. These features are critical for high-voltage battery enclosures, electronics, and commercial architectural systems.

High-rise buildings demand resilient materials to withstand wind and temperature shifts. Our premium curtain walls and thermal-break window systems feature dual-barrier insulating structural polymers, ensuring high energy efficiency, stability, and aesthetics.
The Legacy of Aolijie - Over a Decade of Engineering Quality
Our brand "Aolijie" is closely related to the development of aluminum profiles in China. Since 2000, our founder Mr. Wong has been engaged in the sales of building materials industry. At that time, China's real estate was in a rapid development trend, marking the official start of China's building aluminum profile industry.
Aluminum profiles are an environmentally friendly, low-carbon, sturdy, and durable material. Mr. Wong is keenly aware of the significance of aluminum profiles for future urban architecture, which will surely benefit the world. Therefore, the dream of producing high-quality aluminum profiles emerged from then on.
AO: "A" is the first of all letters and has a No.1 meaning, while "O" refers to "option", so "AO" means "First choice".
LI: "L" refers to "leading", "I" refers to "indicator", so "LI" means "leading indicator".

Providing Clear Answers to Common Engineering and Logistics Inquiries
For standard 6063 structural alloys, our standard minimum wall thickness is typically 0.8mm, depending on the cross-section design. For precision electronic enclosures that require lightweight structures, we can achieve wall thicknesses down to 0.6mm by optimizing our tooling and adjusting extrusion speeds.
We typically recommend 6063-T6. While 6061-T6 offers higher mechanical yield strength, 6063-T6 provides superior thermal conductivity (approximately 200 W/m·K). This makes it ideal for heat dissipation fins, EV cooling systems, and micro-inverter housings.
Our standard production adheres to EN 755-9 and DIN 17615 parameters. For precision electronic and automotive components, we can achieve tighter tolerances (down to ±0.05mm) through post-extrusion CNC machining.
We offer specialized surface treatments, including Class 2 anodizing (20-25 microns layer thickness) and Qualicoat-approved architectural powder coatings. These treatments protect components in coastal and high-UV environments, passing salt spray testing up to 1,000 hours.
Die design and sample extrusion are completed within 7 to 10 days. Once the sample is approved by the client, mass production typically takes 15 to 20 days. Shipping times vary depending on the destination port, with standard transit to North American and European ports ranging from 20 to 35 days.
