Aluminum and aluminum alloy terms and definitions - Part
1: Product and method of processing and treatment
1 Scope
This Part of GB/T 8005 defines the terms and definitions involved in aluminum and
aluminum alloy products and processing techniques.
This Part applies to aluminum and aluminum alloy products and processing techniques.
2 Products
2.1 Aluminum, alloys, alloying elements, impurities
2.1.1
Unalloyed aluminum
Metals, which have an aluminum mass fraction of not less than 99.00% (1XXX
series in wrought aluminum and aluminum alloy designations).
2.1.2
Refined aluminum
The unalloyed aluminum, which has a mass fraction of aluminum not less than
99.90%.
2.1.3
High purity aluminum
The unalloyed aluminum, which has a mass fraction of aluminum not less than
99.999%.
2.1.4
Alloy
A metallic substance, which is composed of matrix metal elements (the element with
the largest mass fraction), alloying elements, impurities.
2.1.5
Aluminum alloy
An alloy, which takes aluminum as its matrix, AND the aluminum mass fraction of
which is less than 99.00%.
2.1.6
Alloying element
Metallic or non-metallic elements, which are added to the base aluminum, in order
to make aluminum and aluminum alloys have certain characteristics.
2.1.7
Impurity
Metal or non-metal elements that exist in aluminum and aluminum alloys BUT are
not intentionally added or retained.
2.1.8
Aluminum master alloy
Low melting point alloys, which use aluminum as the base, by adding one or several
alloying elements, to solve the problems that the element is easy to burn, has a high
melting point and is not easy to melt in, has a high density and is easy to segregate,
OR to improve the properties of the alloy, through melting and other methods. They
are mostly in the shape of waffle ingots, blocks, cakes or wires.
Note: Aluminum master alloys can be divided into alloying type, grain refinement type,
modified type, purification type, etc., according to their uses.
2.1.9
Additive for aluminum alloy
A substance, which is added into the aluminum melt, to adjust the composition of
the aluminum alloy or the as-cast structure. It usually has metallic properties, as
formed by mixing and pressing alloying element powder with aluminum powder
and/or flux. Most of them are in the shape of cakes. It can be used to replace
aluminum master alloy, in aluminum alloy smelting.
2.1.10 Wrought aluminum alloy
2.1.10.1

2.1.10.5
Wrought aluminum magnesium alloy series
Wrought aluminum alloy, which uses magnesium as the main alloying element (that
is, wrought aluminum alloy with the designation of 5××× series).
2.1.10.6
