@First "A" shows aluminum and aluminum alloy
AThe next 4 digits show alloy number. The first digit represents main additive element which is classified as below.
1 | Pure aluminum |
---|---|
2 | Al-Cu alloy |
3 | Al-Mn alloy |
4 | Al-Si alloy |
5 | Al-Mg alloy |
6 | Al-Mg-Si alloy |
7 | Al-Zn-Mg alloy |
8 | Other aluminum alloy |
The second digit shows kinds of aluminum alloy.
0 means basic alloy and 1 to 9 means improved alloy and their derivatives. Only in case of pure aluminum, 0 shows that there is no special regulation on impurities and 1 to 9 shows that there is some special regulation on 1 or more kinds of impurities.
The third and forth digits in case of pure aluminum reveal the minimum percentage of aluminum.
BDesignation showing shape
P | Plate, strip, circular disc |
---|---|
PC | Clad sheet |
H | Foil |
BE | Extruded rod |
BD | Drawn rod |
W | Wire |
TE | Extruded tube |
TD | Drawn tube |
TW | Welded tube |
S | Extrusion |
FD | Casted & forged product |
FH | Open-die forged product |
PB | Extruded conductor |
SB | Extruded conductor |
CDesignation showing temper grade
F | As fabricated |
---|---|
O | Full soft (annealed) |
H | Strain hardened (cold worked) with or without thermal treatment |
W | Solution heat treated only. |
T | Heat treated to produce stable tempers excluding F, O and H. |
T1 | Cooled from hot working and naturally aged (at room temperature) |
T2 | Cooled from hot working, cold-worked, and naturally aged |
T3 | Solution heat treated and cold worked |
T4 | Solution heat treated and naturally aged |
T5 | Cooled from hot working and artificially aged (at elevated temperature) |
T6 | Solution heat treated and artificially aged |
T7 | Solution heat treated and stabilized |
T8 | Solution heat treated, cold worked, and artificially aged |
T9 | Solution heat treated, artificially aged, and cold worked |
T10 | Cooled from hot working, cold-worked, and artificially aged |
Design of extrusion mold -> product -> cut -> bending -> welding -> surface treatment and coating
Surface treatment: buffing, hair-line, chemical polishing, dyeing, anodizing, shot blast, etc.
Coating: Urethane coating, fluorinate coating, ceramic coating, etc.
