When specifying custom aluminium extrusion boxes, electrical enclosures, or structural profiles, selecting the precise alloy temper and post-processing finish is critical to guaranteeing mechanical performance and environmental longevity.
| Alloy Grade | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Thermal Conductivity | Primary Industry Applications |
|---|---|---|---|---|---|
| 6063 Aluminum | T5 / T6 | 200 - 245 MPa | 165 - 210 MPa | 200 W/m·K | Custom electronic box enclosures, architectural facades, window frames, light trim. |
| 6061 Aluminum | T6 | 290 - 310 MPa | 240 - 275 MPa | 167 W/m·K | Heavy-duty structural boxes, industrial assembly lines, automotive frames, CNC parts. |
| 6082 Aluminum | T6 | 310 - 340 MPa | 260 - 290 MPa | 170 W/m·K | High-stress structural beams, solar mounting rails, marine bridges, outdoor platforms. |
| 5052 Aluminum | H32 | 210 - 260 MPa | 130 - 180 MPa | 138 W/m·K | Sheet metal box covers, marine enclosures, severe anti-corrosion chemical housings. |
Our 5-axis CNC machining centers maintain wall-thickness tolerances down to ±0.1mm, ensuring exact board-slot alignment and airtight gasket sealing for waterproof IP67 aluminium boxes.
Choose from Hard Coat Anodizing (up to 25μm thickness for scratch protection), Fluorocarbon PVDF spraying (>3,000 hrs salt-spray resistance), or wood-grain thermal transfer finishing.
Custom extrusion dies enable seamless integration of external heat sink fins into the main box body, eliminating thermal resistance and boosting passive cooling performance for high-power electronics.

Examine how Qianyu Aluminum Industry solves complex structural and thermal challenges across diverse high-performance commercial and industrial environments.
Product Overview: Aluminum alloy flooring is designed for high-performance applications where durability, lightweight structural integrity, and superior corrosion resistance are essential. Utilizing advanced high-pressure die-casting technology combined with precision profile extrusion, these floors are formed from virgin aluminum ingots, resulting in a high-density, ultra-strong module.
Key Performance Metrics:
Product Overview: Engineered from high-grade 6xxx-series structural alloys (tensile strength 200–350 MPa), our architectural pergola extrusions deliver structural resilience while weighing 60% less than equivalent steel framing. Ideal for rooftop installations, coastal resorts, and municipal plazas.
Project Highlights:
Product Overview: Modern high-rise curtain wall assemblies and industrial facility siding require low mass combined with strict wind-load resistance. Our thermal break aluminum profiles reduce building HVAC energy loss while offering flexible aesthetic finishes.
Manufacturing Capabilities: Fast-track delivery supported by a 5,000-ton raw material billet stock and 50,000+ existing extrusion dies, guaranteeing 30% shorter lead times for global enterprise contractors.
From raw material ingot verification to final export dispatch, Qianyu Aluminum Industry maintains strict ISO 9001:2015 protocol across all 6 core production stages:
Our senior engineering team reviews client CAD/STEP files for Design for Manufacturability (DFM), optimizing wall thicknesses, corner radii, and die flow channels within 24 hours.
We manufacture extrusion dies in-house with high-speed CNC EDM cutters, reducing sample turnaround times to just 48–72 hours for custom extrusion box profiles.
Operating multiple extrusion presses ranging from 800 tons to 5,000 tons, we produce complex solid, semi-hollow, and hollow box profiles with maximum structural density.
Post-extrusion operations include multi-axis CNC milling, precision drilling, tapping, bending, laser cutting, and robotic welding for turn-key enclosure assembly.
Automated anodizing lines, powder coating booths, and PVDF spraying guarantee uniform coating thickness (8μm to 25μm+) and vibrant, fade-resistant color matching.
Every shipment undergoes 100% optical dimensional inspection, salt-spray testing, and protective film wrapping inside ISPM-15 compliant sea-worthy wooden crates.
Our products comply strictly with international structural and environmental standards including ISO 9001, RoHS, REACH, and LEED green building certification.

Get direct answers from our technical engineering team regarding custom aluminium extrusion box manufacturing, die tooling costs, tolerances, and international lead times.
Answer: For standard custom extrusion dies (including custom aluminium box profiles), initial die tooling and 3D sample production take approximately 7 to 10 business days. Once the sample is approved by your engineering team, full-scale mass manufacturing typically takes 15 to 20 days depending on volume and surface finish requirements (e.g., anodizing or PVDF coating).
Answer: Custom extruded aluminum boxes offer significantly greater structural length flexibility (up to 6+ meters) and lower tooling costs for medium-to-large enclosures compared to expensive die-casting molds. Extruded 6063-T6 boxes also exhibit higher tensile strength and smoother surface finishes. Integrated tongue-and-groove tracks allow silicone sealing gaskets to easily achieve waterproof IP65, IP67, or IP68 ratings.
Answer: For severe outdoor or marine environments, we recommend 6061-T6 or 6082-T6 alloy paired with a 15–25 micron Hard Coat Anodized finish or 3-coat Fluorocarbon PVDF paint. This combination resists salt-spray corrosion for over 3,000 continuous hours without surface pitting or oxide flaking.
Answer: Yes. We operate complete in-house 3-axis, 4-axis, and 5-axis CNC machining centers. We perform precision cutting, hole drilling, slot milling, counter-boring, thread tapping, laser engraving, and custom end-plate assembly so your aluminium boxes arrive ready for direct component installation.
Answer: Our manufacturing plant operates under strict ISO 9001:2015 quality management system standards. All raw materials conform to ASTM B221, EN 755, and GB/T 5237 specifications. Furthermore, our surface treatments are fully RoHS and REACH compliant, aligning with European Union and North American environmental directives.
