Product Application
Aluminum Profiles for Modern Industrial Applications
Key Components Utilizing Extruded Aluminum Profiles in New Energy Electric Vehicles (NEVs)
Extruded aluminum profiles are fundamental to the lightweighting, structural integrity, and performance of New Energy Electric Vehicles (NEVs). Their application spans several critical systems:
-
1
Battery System: This is the most significant application. Battery Enclosure Trays and Cross Members are primarily constructed from complex, multi-void extruded profiles. They provide a rigid, protective structure for battery modules while minimizing weight. Internal Cooling Plate/Channel profiles are also extruded to form the foundational part of the thermal management system.
-
2
Body & Chassis Structure: Aluminum extrusions are key in space frame designs and as reinforcement elements. They are used in Crash Management Systems (front and rear crash boxes, side sill reinforcements), A/B/C Pillar reinforcements, Roof Rails, and Subframe components. Their high strength-to-weight ratio and excellent energy absorption are crucial for safety and efficiency.
-
3
Thermal Management: Beyond battery cooling, extruded profiles form the main heating/cooling plates for the Power Electronics (e.g., inverter, DC-DC converter) and are often integrated into Motor Housings to manage heat from the e-drive unit.
-
4
Interior & Exterior: Applications include Side Impact Door Beams, Bumper Beams, Seat Frame components, and various Cross-car Beams. Their use enhances safety and reduces cabin weight.
-
5
Other Systems: Drive Shaft Tubes (for lightweighting) and structural supports for Charge Port housings also utilize specialized extrusions.
🎯
Precision is non-negotiable. We supply sheets with superior dimensional consistency, featuring tight thickness tolerances (as low as ±0.1mm) and exceptional flatness. This is crucial for reliable laser welding or FSW (Friction Stir Welding) processes, ensuring leak-proof seams for liquid-cooled systems and maintaining the critical seal that protects sensitive battery cells from moisture and contaminants.
Frequently Asked Questions
Q
What aluminum alloy grades are available for your pipe aluminum profiles?
We offer pipe aluminum profiles in three primary alloy grades: 6063, 6061, and 6060. Each grade offers different balances of strength, corrosion resistance, and extrudability. The most commonly used is 6063 for architectural applications, while 6061 is preferred for structural and industrial uses requiring higher strength.
Q
What surface treatment options do you offer for aluminum profiles?
We provide a comprehensive range of surface treatments including Mill Finish, Powder Coating, Anodizing, Electrophoresis, Fluorocarbon Coating, and Wood Grain finishes. Custom colors and finishes are available according to customer requirements to meet specific aesthetic or functional needs.
Q
What is the minimum order quantity (MOQ) and what are the lead times?
Our minimum order quantity is 500 kg. For lead times, die development and sample testing typically takes 7–10 days, while mass production is completed within 15–30 days depending on order volume and profile complexity.
Q
Can you provide custom aluminum profiles with specific dimensions and tolerances?
Yes, we specialize in custom aluminum extrusions. We can produce profiles with thickness ranging from 0.8 mm to 5.0 mm, with lengths up to 6 m (customizable). Our precision manufacturing ensures tight dimensional tolerances as low as ±0.1 mm, which is critical for applications such as laser welding and FSW processes in battery and thermal management systems.
Q
What value-added services do you offer beyond extrusion?
We offer a full suite of value-added services including Drilling, Milling, Cutting, Welding, Bending, Assembling, and CNC machining. This allows us to deliver ready-to-use components or sub-assemblies, reducing your production steps and overall lead time.
Q
Are your aluminum profiles suitable for New Energy Electric Vehicle (NEV) applications?
Absolutely. Our extruded aluminum profiles are widely used in NEV applications including battery enclosure trays, cooling plates, body and chassis structural components, crash management systems, door beams, bumper beams, and drive shaft tubes. Their high strength-to-weight ratio and excellent thermal conductivity make them ideal for modern electric vehicle design and manufacturing.
