2. Physical Specification

* Weight per ingot: ~20–25 kg (typical 22.7 kg ± 1.5 kg) * Shape: Standard pigs / T-ingots * Surface: Smooth, no cracks, low porosity * Melting process: Electrolytic primary aluminum (from alumina)

⸻

3. International Standards

A7 aluminum is commonly produced under or equivalent to:

* ASTM standards (various aluminum product standards) * EN / DIN European standards * JIS (Japan Industrial Standards) * GB/T 1196 (China standard for aluminum ingots) * ISO quality management systems (ISO 9001 in many suppliers)

⚠️ Note: “A7” is a commercial grade designation, not always a single unified global standard. Composition may vary slightly by producer.

4. Packaging & Delivery

* Bundle weight: ~950–1000 kg per bundle * Ingot per bundle: ~40–44 pieces * Strapping: Steel or PET straps (2 cross + 3 longitudinal straps) * Protection: Plastic wrap / anti-oxidation wrapping (optional) * Container loading: 20ft / 40ft containers, bulk stacked

⸻

5. Quality Requirements

Typical required quality controls:

* Certificate of Analysis (COA) * Mill Test Certificate (MTC) * Third-party inspection (SGS / BV / Intertek) * Controlled impurity limits (Si, Fe strictly monitored) * No slag, oil contamination, or excessive oxidation

⸻

6. Uses / Applications

A7 aluminum ingots are widely used as primary raw material for:

Industrial manufacturing:

* Aluminum alloy production (ADC12, A356, etc.) * Rolling (sheet, foil) * Extrusion (profiles, frames) * Casting industries

Construction:

* Doors, windows, curtain walls * Structural aluminum parts

Transport:
