Unalloyed Aluminum Ingots for Remelting
1 Scope
This document specifies the classification, technical requirements, test methods, inspection
rules, marking, packaging, transportation, storage, quality certificate and order sheet (or
contract) content of unalloyed aluminum ingots for remelting.
This document is applicable to unalloyed aluminum ingots for remelting (hereinafter referred
to as the “aluminum ingots”) produced through the alumina-cryolite molten salt electrolysis
method.
Electrolytic primary aluminum liquid may take this Standard as a reference.
2 Normative References
The contents of the following documents constitute indispensable clauses of this document
through the normative references in the text. In terms of references with a specified date, only
versions with a specified date are applicable to this document. In terms of references without a
specified date, the latest version (including all the modifications) is applicable to this document.
GB/T 7999 Optical Emission Spectrometric Analysis Method of Aluminum and Aluminum
Alloys
GB/T 8170 Rules of Rounding off for Numerical Value & Expression and Judgement of
Limiting Values

3 Terms and Definitions
This document does not have terms or definitions that need to be defined.
4 Classification
In accordance with the chemical composition, the product can be classified into eight
designations: Al99.85, Al99.80, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E and Al99.6E.
this document or the order sheet (or contract), and a quality certificate shall be filled out.
7.1.2 The demand-side shall inspect the received products in accordance with the provisions of
this document. If the inspection results are inconsistent with the provisions of this document or
the order sheet (or contract), for the aluminum ingots, it shall be proposed to the supply-side
within 30 days from the date of receipt of the product and resolved by the demand-side and the
supply-side through negotiation. If arbitration is demanded, the demand-side shall jointly
conduct the arbitration sampling. The inspection and acceptance of primary aluminum liquid
shall be settled by the demand-side and the supply-side through negotiation.
7.2 Group Batch
7.2.1 The aluminum ingots shall be submitted for inspection in batches. Each batch shall be
composed of products of the same batch No., with no limit on batch weight.
7.2.2 The primary aluminum liquid shall be submitted for acceptance in batches. Each batch
shall be a single aluminum liquid package.
7.3 Inspection Items
Each batch of products shall be inspected for chemical composition. The weight of a single
aluminum ingot is not inspected and is guaranteed by the supply-side’s workmanship. The
aluminum ingots shall be inspected for appearance quality.
7.4 Sampling and Sample Preparation
7.4.1 Inspection of chemical composition
7.4.1.1 Respectively take an aluminum ingot from the top, middle and bottom of any bundle of
the batch of aluminum ingots. When the aluminum ingots are scattered and it is difficult to
distinguish the upper, middle and lower parts, then, no less than 3 PCS shall be randomly
sampled.
7.4.1.2 Use ethanol as a lubricant and use a drill bit with a diameter of 15 mm ~ 20 mm to drill
holes for sampling.
7.4.1.3 On the larger surface of the aluminum ingot, along its diagonal, drill 3 holes, with one
in the center and the other two about 100 mm from the angular point. The depth of each borehole
must be no less than two-thirds of the original thickness. Before drilling the specimen, the
surface oxide layer shall be removed first, with a thickness of not less than 0.5 mm.
7.4.1.4 The aluminum chips obtained through drilling shall be evenly mixed, treated with
magnets and divided into quarters using the method of quartering. The weight shall be no less
than 100 g.
7.4.1.5 For the sampling and sample preparation for the chemical composition of the primary
aluminum liquid, see YS/T 1004.
7.4.2 Inspection of appearance quality
The appearance of the aluminum ingots shall be inspected PCS by PCS.
7.5 Determination of Inspection Results
7.5.1 When the chemical composition is disqualified, the batch of products shall be determined
as disqualified. However, the designation can be re-determined based on the analysis results.
7.5.2 When the appearance quality of the aluminum ingot is disqualified, the PCS shall be
determined as disqualified.
8 Marking, Packaging, Transportation, Storage and Quality
Certificate
8.1 Marking
8.1.1 Each aluminum ingot shall be cast or printed with the manufacturer’s marking and batch
No.
8.1.2 Each bundle of aluminum ingots shall be marked with bright colors, waterproof and not
easy to fall off, and there shall be no less than two markings, indicating the serial No. of this
document, batch No., bundle No., net weight, number of pieces and designation. It is
recommended to use a label that indicates the product name, serial No. of this document, batch
No., bundle No., net weight, number of pieces, designation, production date, manufacturer’s
name, factory address and barcode (see YS/T 1209 for coding rules).
8.1.3 When the demand-side has special requirements for the marking, they shall be negotiated
by the demand-side and the supply-side and specified in the order sheet (or contract). The
product identification of green-power aluminum is shown in T/CNIA 0168.
8.2 Packaging
8.2.1 Steel straps, high-strength plastic packaging straps or other materials can be used for
bundling and packaging, but it shall be ensured that the aluminum ingots are not loosely bundled.
8.2.2 The steel straps used for bundling shall be rust-proof, and the size, tensile strength,
elongation and other performance indicators shall comply with the stipulations of Table 2. Other
requirements shall comply with the relevant stipulations of GB/T 25820. When the demand-
side has special requirements, they can be separately agreed in the order sheet (or contract).
