Deploying national high-precision metallurgical profiles customized for advanced industrial applications, aerospace support frames, and heavy-duty mechanical engineering components.
Integrating scientific material research, heavy mechanical extrusion engineering, and state-of-the-art surface treatments under strict quality controls.
Founded on the corporate philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation", Chengdu E&I Aluminum Industry Co., Ltd. (EI Alu Extrusion Factory) has evolved into an industry-leading manufacturer of high-difficulty, high-precision, and heavy-duty structural aluminum profiles.
Collaborating with the National Institute of Nonferrous Metals, we field one of the most professional light alloy engineering R&D teams in Southwest China. We don't just extrude metal; we configure structural aluminum solutions across profiles, castings, and forgings to optimize global industrial infrastructure.
Our operational capabilities bridge the gap between design and high-volume output. We feature advanced extrusion lines (ranging from light profiles to massive structural sizes), automated chemical anodizing, powder coating, and precision CNC post-processing. From Fortune 500 automotive OEMs to precision aerospace facilities, our profiles form the structural backbone of critical applications.
In the global shift toward decarbonization, structural lightweighting, and automated production lines, customized aluminum extrusions are essential structural components.
Integrated modular frames, assembly conveyor guide rails, and robot safety enclosures require precise T-slot interfaces to allow for rapid updates. Our profiles reduce mechanical assembly labor while maintaining structural strength.
We provide structural battery enclosures, crash boxes, and lightweight body structures. Lower weight directly translates to increased range for Electric Vehicles (EVs) and reduced emissions for traditional combustion engines.
Solar photovoltaic supports and wind turbine access framing require structures capable of enduring extreme outdoor environments. Our anodized finishes provide corrosion protection against high salt air and moisture.
Collaborating with aerospace logistics partners, we develop non-magnetic, structural ground support frames and flight maintenance platforms, keeping safety margins high under challenging loads.
Choosing the correct aluminum alloy and profile cross-section dictates the structural safety and lifespan of your systems. Below is an engineering overview of our core alloy families.
| Alloy Grade | Temper Specification | Yield Strength (MPa) | Typical Applications | Corrosion Resistance |
|---|---|---|---|---|
| 6063 | T5 / T6 | 170 - 210 | Standard T-Slot frameworks, automated conveyor profiles, display equipment. | Outstanding (Anodized) |
| 6061 | T6 | 240 - 275 | Heavy-load machinery bases, automotive components, highly stressed weldments. | Excellent |
| 6005A | T61 | 215 - 250 | Structural framing for high-vibration railway cars, truck panels, marine structures. | Excellent |
| 7075 | T6 | 430 - 480 | High-stress aerospace components, heavy equipment components requiring steel-like strength. | Moderate (Requires Treatment) |
We strive to position Chengdu E&I Aluminum Industry Co., Ltd. within the top tier of China's light-alloy engineering manufacturers in terms of material innovation, structural design capacity, and smart production integration.
By delivering high-value products to global engineering networks, we build shared growth channels. We prioritize long-term technical value over short-term volume gains.
We specialize in manufacturing aluminum profiles that align with international structural codes and regional compliance directives, allowing for smooth project integration.
Our profiles are extruded according to high-precision engineering standards, matching EN 755 (European standard for aluminum extrusions), ASTM B221 (American Society for Testing and Materials), and the national GB/T 5237 (Chinese high-precision grade profile specifications) standards.
Our processing lines manage precise film build, thickness uniformity, and sealing parameters. We provide architectural and industrial grade anodizing (up to Class I, >18µm) to prevent surface oxidation in marine or chemical-heavy manufacturing atmospheres.
We support our global integration partners through customized structural layout CAD engineering, custom-built extrusion dies, and standardized packaging configured for international freight, minimizing damage and assembly delays.
Deploying manufacturing systems that align with global green energy and resource efficiency expectations.
Moving toward using primary aluminum smelted with renewable energy (hydroelectric/solar) to lower the carbon footprint of our profiles for customers tracking Scope 3 emissions.
Integrating real-time laser profile scanners and automated visual defect detection on our run-out tables to catch micro-cracks, surface marks, and dimensional drift during extrusion.
Developing ultra-thin wall extrusions and liquid cooling plates to support the next generation of electric vehicle power electronic thermal controls and cloud computing server racks.
