It is used to adjust and control the chemical composition and structure of cast aluminium alloys or wrought aluminium alloys. The mass fraction of the main alloying elements can exceed 50%. 4 Requirements 4.1 Product classification 4.1.1 Representation method of aluminium hardener designation The designation of aluminium hardeners is composed of “Al” + the symbol of the main alloying element + the nominal mass fraction of the main alloying element. The main alloying elements are arranged in descending order by their element mass fractions. When the nominal mass fractions of the main alloying elements and the main alloying elements are the same, but the impurity elements are different or the mass fractions of the impurity elements are different, the suffix English letters indicate different impurity control requirements. Examples are as follows: Example 1: Designation of aluminium hardeners with one main alloying element Example 2: Designation of aluminium hardeners with two main alloying elements 4.1.4 Marking and examples The marking of aluminium hardeners is expressed in the order of product category, number of this Standard, designation of the aluminium hardener, designation of the raw aluminium ingot (which can be omitted when designation Al99.70 is selected), dimensions and piece weight. Examples of marking are as follows: Example 1: The aluminium hardener, with the designation of aluminium hardener AlB3, the designation of raw aluminium ingot Al99.70, the thickness 40 mm, the width 220 mm, the length 420 mm, and the weight per piece 7 kg, is marked as: Ingot GB/T 27677-AlB3-40×220×420-7 Example 2: The aluminium hardener, with the designation of aluminium hardener AlCa5, the designation of raw aluminium ingot Al99.70, the wire diameter ϕ9.5 mm, and the weight per coil 200 kg, is marked as: Wire coil GB/T 27677-AlCa5-ϕ9.5-200 Example 3: The aluminium hardener, with the designation of aluminium hardener AlCa10, the designation of raw aluminium ingot Al99.70, the wire diameter 9.5 mm and the weight per bundle 5 kg, is marked as: Wire rod GB/T 27677-AlCa10-ϕ9.5-5 Example 4: The aluminium hardener, with the designation of aluminium hardener AlB3, the designation of raw aluminium ingot Al99.70, the thickness 30 mm, the width 250 mm, the length 250 mm, and the weight per piece 5 kg, is marked as: Ingot GB/T 27677-AlSc2(Al99.90)-30×250×250-5 5.3 Microstructure Microstructure shall be inspected in accordance with the provisions of GB/T 3246.1. 5.4 Appearance Visually inspect the appearance under natural scattered light. 6 Inspection rules 6.1 Inspection and acceptance 6.1.1 The aluminium hardeners shall be inspected by the supplier to ensure that the quality of the aluminium hardeners complies with the provisions of this Standard and the order form (or contract), and a quality certificate shall be filled in. 6.1.2 The buyer shall inspect the received aluminium hardeners in accordance with the provisions of this Standard.
