Commercial definition
Aluminium extrusion profiles traded for alloy consistency and preparation, with attention to paint, anodising, thermal breaks, screws and iron.
Specification framework
| Parameter | Commercial expectation |
|---|---|
| Metal / recovery basis | Predominantly 6063 when sold as alloy-specific |
| Moisture | Dry |
| Contamination | Thermal-break plastics, iron screws, rubber, glass and other alloys controlled |
| Not permitted unless agreed | Excessive thermal-break material, mixed castings or unreported alloy mix |
| Packaging | Bundles, bales or loose profiles |
Inspection priorities
Use alloy verification where needed; check thermal breaks, paint, screws, mixed 6000-series grades and profile cleanliness.
- Verify stock identity and ownership before relying on photographs or video.
- Use representative sampling rather than inspecting only the visible outer layer.
- Record gross, tare and net weight basis and reconcile it with shipping documents.
- Agree the claims procedure, notification period and testing method before shipment.
Packing and loading
Bundles, bales or loose profiles. Container suitability, floor loading, securing, bale or bundle dimensions, seal control and photographic evidence should be considered before dispatch.
Commercial considerations
Pricing is influenced by recoverable metal, reference-market movements, processing cost, contamination risk, freight, financing, destination requirements and the timing mechanism in the contract. A large headline discount can be misleading when the specification or payment risk is weak.
Typical end uses: Extrusion billet and secondary alloy production
Frequently asked questions
Is the stated purity guaranteed by the grade name?
No. The grade name is commercial shorthand. Purity or recovery must be supported by an agreed specification, representative evidence and the contractual inspection method.
Can moisture and contamination simply be deducted at destination?
Only if the contract defines how they are measured, the acceptable limits, the independent party or laboratory, and the settlement formula.
Is third-party inspection sufficient on its own?
Inspection can reduce risk but does not replace counterparty due diligence, secure payment terms, document verification and clear title to the material.
