Aluminium Quality Control & Documentation
Chemistry per heat by optical emission spectrometry, dimensional and ultrasonic inspection to agreed criteria, EN 10204 3.1 certificates and batch traceability through to the shipping documents.
What Is Verified & Documented
Every heat is tested for chemical composition by optical emission spectrometry and reported against the alloy limits of the designation standard named on the order. Dimensions are inspected to the tolerances agreed in the specification, and ultrasonic inspection of billet is available on request.
Documentation is agreed before the order rather than assumed afterwards. The usual set is an EN 10204 3.1 material test certificate with chemistry results, heat traceability, a packing list and a certificate of origin, extended where your process needs treatment records or sustainability declarations.
Scope matters more than document names. State the values, test methods, sampling and acceptance criteria your approval process relies on, and the agreed scope is recorded in the supply proposal.
Controls Applied To Billet & Bar
Chemistry Per Heat
Chemical composition is tested per heat by optical emission spectrometry and reported against the alloy limits of the named designation standard.
Dimensional Inspection
Diameter, length and squareness are checked against the agreed tolerances. Sampling and acceptance criteria are recorded in the order specification.
Ultrasonic Inspection
Ultrasonic inspection of billet is available on request. State the acceptance standard and reporting format your approval process requires.
Identification & Packing
Bundles are identified so that material, inspection records and shipping documents can be linked on receipt.
Document Set To Agree Before Ordering
Confirm which records are required, and what each one must state, as part of the enquiry.
| Document Or Record | What To Specify |
|---|---|
| Material test certificate (EN 10204 3.1) | Alloy, temper, reported elements, agreed limits, test method and batch reference. |
| Chemical composition report | Per-heat OES results against EN 573-3, ASTM B221, GB/T 3190, JIS H4100 or IS 733 as named on the order. |
| Dimensional inspection record | Diameter, cut length, tolerances, sampling and acceptance criteria. |
| Heat / batch traceability | How billet or bar identification connects material, inspection record and shipping documents. |
| Treatment record | Evidence for the agreed delivery condition where a homogenised or other specified condition is required. |
| Packing list & certificate of origin | Bundle identification, quantity, weight basis and export documentation for the shipment. |
| Sustainability records | ASI or recycled-content statements and CBAM reporting support, where the exact scope is agreed for the order. |
How Acceptance Is Defined
- A document name is not an acceptance specification — define the values, test methods and traceability links that matter for your part.
- An alloy designation alone does not cover dimensions, surface condition, treatment, inspection or documentation.
- Certificates, recycled-content declarations and carbon values are confirmed per product and per order, not claimed as a blanket statement.
- Tolerances are supplied to your specification; indicative values are confirmed in the offer before the order is placed.
- Agree sampling, inspection arrangements and report language in the enquiry so the supply proposal records the scope.
