Hello everybody

Alum per QQ-A-250/11 TEMP T6 OR T651 (REF: AL 6061-T6 OR T651)

This looks to me Alum Plate. If any body can explain which code represents the plate or flat bar and which represents the heat treatment of the material. If this is plate than what code represents the flat bar?

Thanks in advance

T is for temper, I don't think it has to do with plate or bar, but maybe I am wrong. I would ask my material vendor, I suggest that's who you ask.

What represents Plate and what represents the flat bar? This is my main concern.

QQ-A-250/11 is plate

 

QQ-A-200/8 is extruded bar

[Ralph@Faustson]

I believe QQ-A-250/8 is extruded bar QQ-A-250/11 is plate

There is a long spec for the "T6/T651/Etc". It has to do with the alloy mix and the temper of the material. I've got a book of all the tempers and what they mean somewhere in the shop here, but I really only care what the spec on the print says.

 

The rest of the info people have for bar or plate is correct. Try doing a google search for the spec and you will find suppliers that will give you the info on the web.

T651 is a plate as I know

with cnc work, you will not notice big different

but if you have long holes like cooling holes

use only T651, cause there is a big different in drilling it

I just spoke with our material supplier and did a few searches, as I tought, -6, -651, -6511 are all tempers. While some tempers may be more common to material shapes, the temper designation has nothing to do with shape.

 

So, if you want plate, you better specify plate, if you want cold finished bar or extruded bar, you better specify that.

 

In our system, we customized it to state material shape.

t651 moves less than t6. If you don't want the part to move after machining, use t651.
