3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
aluminium hardeners
An alloy made of aluminium as a matrix and melted with other metals or non-metals at
elevated temperatures. 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
