Custom Extruded Aluminum Profiles
Our quality team rigorously monitors the entire manufacturing process of extruded aluminum components, from raw materials to finished product delivery, ensuring customer needs and satisfaction.
Aluminum Enclosure
Custom extruded aluminum enclosures are widely used for electronic and industrial applications. Designed for durability and precision, they can be combined with CNC machining and surface finishing to achieve accurate dimensions, reliable protection, and a clean appearance.
Aluminum Heat Sink
Extruded aluminum heat sinks provide efficient thermal management for electronic components. Optimized fin structures and profile design ensure effective heat dissipation, while secondary machining enables precise mounting and integration.
Glass Fence Floor Trough
Extruded aluminum floor troughs are designed for glass railing systems, offering strong structural support and secure installation. Profiles can be customized to match different glass thicknesses and project requirements, with excellent corrosion resistance for indoor and outdoor use.
Aluminum Window Profile
Aluminum window profiles are engineered for strength, weather resistance, and long-term durability. Extrusion allows complex cross-sections for insulation and sealing, making them suitable for modern architectural and construction applications.
Common Aluminum Material for Aluminum Extrusion
Aluminum 6061
Al–Mg–Si
6061 aluminum is a versatile alloy widely used in aluminum extrusion. It provides a good balance of strength, corrosion resistance, and structural performance. In extrusion applications, 6061 is ideal for structural profiles, frames, and load-bearing components that require higher strength and can also support secondary CNC machining for precision features.
Aluminum 6063
Al–Mg–Si
Aluminum 6082
Al–Mg–Si
6082 aluminum is a high-strength alloy commonly used in Europe as an alternative to 6061. It offers higher mechanical strength and good resistance to stress corrosion cracking, while maintaining suitable extrudability. In aluminum extrusion, 6082 is often used for structural profiles and load-bearing components that require enhanced strength.
Aluminum 7075
Al–Mg–Si
7075 aluminum is a high-strength aerospace-grade alloy with exceptional hardness and fatigue resistance. It is less suitable for extrusion but can be used for simpler profiles requiring very high strength. In aluminum applications, 7075 is typically used for critical structural parts and components that demand maximum strength-to-weight performance.
Aluminum Extrusion Design Guide
Avoid overly deep cavities, grooves and holes
The depth of the cavity and groove is usually related to the diameter of the tool used to make the internal fillets. Keep the cavity depth 3 – 4 times the tool diameter or the groove depth less than 4 times the feature width. Blind holes or Through holes(Suggestion):
- Standard-size holes: can be machined quickly and with high precision
- Maximum depth: 4 times the diameter
- Minimum hole diameter: 1 mm
Using an end mill will increase costs for non-standard holes.
Avoid right angles
Avoid right angle designs in recessed areas. CNC milling and turning usually use cylindrical tools, which cannot cut a perfect right angle and usually leave a small radius. Therefore, during milling, the corners of the concave areas are all rounded.
Avoid thin walls
Vibration increases when machining thin features. The minimum thickness of thin-walled aluminum parts should be 0.5-0.8 mm. If the walls are for supporting action or taller features, the thickness should be increased to avoid vibrations during CNC machining
Avoid small or raised logo
Adding text in the custom CNC machining is time-consuming to process.
electrochemical etching or laser marking is usually better. If you must cut text, choose recessed rather than raised text whenever possible, with a font depth of no more than 0.3mm.
Stick to the standards for threads
Sticking to standard sizes is important when creating threads.
- Length: a maximum of 3 times the nominal diameter of a hole.
For blind hole tapping, it is preferable to add a length of at least 1/2 hole diameter at the root of the hole. You could think about using inserts. threaded coils provide longer service life than bare threads, especially in soft materials such as aluminum, and are easy to install.
We strictly adhere to ISO quality standards and have been certified to ISO 90001: 2015. Our production lines use advanced technology to ensure manufacturing precision and accuracy. With in-house advanced measuring and testing equipments, we can verify that all materials and products meet your specifications.
