Tense
Aluminum 6063 — Tense
Clean, mill-finish 6063 extrusion scrap. Free of paint, anodizing, iron, plastic, glass, dirt and tape. The cleanest grade of 6063 we offer.
We focus exclusively on aluminum 6063 — the architectural extrusion alloy. Every grade below is ISRI-coded, source-verified, and shipped with full documentation.
Clean, mill-finish 6063 extrusion scrap. Free of paint, anodizing, iron, plastic, glass, dirt and tape. The cleanest grade of 6063 we offer.
Painted and/or anodized 6063 extrusions. Sorted by alloy with mixed surface treatment. Slight discount to Tense, equal melt-yield.
Mixed extrusion with thermal-break inserts. Mechanical separation pre-shipment to maintain melt yield and alloy chemistry.
10/10 mixed clean aluminum scrap consisting of clean unalloyed and 6063 alloy. Industrial sourced. Contamination < 1%.
Old extrusion, mixed with paint, glass, and minor steel attachments. Pre-cleaned to ISRI Tata specification before container loading.
Need a specific blend, chemistry, or pre-sorted batch? We work with you to source against your smelter's exact furnace recipe.
Standard chemical composition for 6063 — the alloy behind virtually all architectural aluminum extrusions.
| Element | Min % | Max % | Note |
|---|---|---|---|
| Aluminum (Al) | 97.5 | Bal. | Base metal |
| Magnesium (Mg) | 0.45 | 0.90 | Strength contributor |
| Silicon (Si) | 0.20 | 0.60 | Pairs with Mg for hardening |
| Iron (Fe) | — | 0.35 | Impurity, kept low |
| Manganese (Mn) | — | 0.10 | Trace |
| Zinc (Zn) | — | 0.10 | Trace |
Window frames, door profiles, curtain walls, modular kitchens — the original home of 6063.
Body trims, roof rails, sunroof frames, EV battery enclosures — modern auto's lightweighting workhorse.
Solar mounting structures and wind-turbine cabling housings — corrosion resistance is non-negotiable.
Heat exchanger fins, condenser frames, ducting — high thermal conductivity, low weight.
Heat-sink extrusions, LED housings, server-rack frames — clean melt = clean surface.
Conveyor profiles, pneumatic frames, modular automation systems — strength-to-weight at scale.
