Coordinate deliveryWhy Extrusion?
Extrusion produces a continuous cross-section. Die geometry, alloy, length and downstream machining define the finished profile.
- ✓Custom cross-section — any 2D profile (within envelope) extruded continuously — heat sinks, structural frames, trim, rails, enclosures
- ✓One die, repeatable cross-section — a profile die costs $500–$3,000 and produces profiles for years
- ✓Excellent surface finish — anodizing and powder coating in any color — architectural and decorative quality
- ✓Integrated functions — extrude screw bosses, snap-fit grooves, wire channels, and thermal interfaces directly into the profile

Alloy Selection Guide
The four most common extrusion alloys:
- ✓6063 — best surface finish (anodizes beautifully), moderate strength — architectural, decorative, heat sinks
- ✓6061 — higher strength (structural), good weldability and machinability — frames, structural applications
- ✓6005A — high strength with good extrudability — structural, solar frames, bike frames
- ✓7075 — very high strength (aircraft grade), poor weldability and finish — high-stress aerospace parts
Design for Extrusion
Profile design decisions that control cost and quality:
- ✓Uniform wall thickness — varying walls extrude at different rates and distort — keep walls within ±20% of each other
- ✓Hollow sections — may use a porthole or other suitable die route; review seam requirements and cost for the alloy and section. The published 2× cost comparison is a planning reference, not a fixed tooling ratio
- ✓Sharp corners — minimum 0.5mm external radius; internal corners 1.0mm+ — sharp corners stress the die and crack the aluminum
- ✓Tolerance zone — specify critical dimensions to ±0.15mm and non-critical to ±0.25mm — every tight dimension increases rejection rate

Frequently Asked Questions
How much does a custom die cost?
Solid profile dies run $500–$1,500; hollow (porthole) dies $1,200–$3,000. Larger and more complex profiles cost more. The die is your property and typically lasts for 5+ years of production. At volumes above 2 tons/year, die cost per part becomes negligible.
What's the MOQ for custom extrusions?
200kg per profile per order — that's roughly 100–400m of a typical medium profile. Below 200kg, the extrusion press setup and die changeover costs dominate. For small quantities of standard profiles, we stock common shapes in mill finish.
How long does anodizing last?
The published 25μm architectural and 10–15μm standard thickness references must be tied to the finish specification, sealing, exposure and maintenance conditions; thickness alone does not establish a 25+ year life. ASTM B136 evaluates sealing through dye-stain resistance, not general corrosion or outdoor durability. Agree the relevant exposure and appearance acceptance tests separately.
Can you extrude in small quantities for prototypes?
Not custom profiles (the 200kg MOQ applies). But for prototyping, we CNC machine profiles from plate or use stock profiles that approximate your design. For geometry validation, 3D printing in aluminum is also an option. We'll recommend the fastest path to your test parts.
