What does the number in " 6061 aluminum " mean ?
In article ,
says...
What does it mean when I see something like " lot of 6061 aluminum tubes" ?
I mean what does the number mean and how can I make sense of it ?
Thanks !
From "Alloy and Temper Designation Systems for Aluminum"
1xxx 99%+ aluminum
2xxx copper
3xxx manganese
4xxx silicon
5xxx magnesium
6xxx magnesium & silicon
7xxx zinc
8xxx other
9xxx unused
The first digit refers to the major alloy group. In the 2xxx thru 8xxx
alloys, the last three digits are assigned arbitrarily to identify
specific alloys.
