unknown alumiun composition 2

[freddyolen]

Could anyone help me with this composition

Al 97%
Cu 0.4%
Mg 0.7%
Si 0.8%
Mn 0.5%
Fe 0.22%
Zn 0.04%

It seemed to be a 6082 alloy but the Cu is to high for this alloy. Anyone got a clue?

Can you provide some information about the product form (sheet, rod, etc.)? Do you have a more complete chemical analysis? It is possible that this is alloy 6016, but this is a free-machining bar alloy that contains Bi & Pb in addition to the elements that you listed. It almost meets the requirements for 6056-- Zn would need to be 0.1-0.7.

Dear TVP ;

The part is an automotive part we've analysed.
It also includes Cu2 : 0.5
Pb 0.04
Cr 0.195
Ti 0.030
Ni : 0.019

It indeed leads to 6056 only for the Zn.

Thanks anyway

freddyolen,

Was the part formed from sheet or from bar/wire? What type of part is it?

 

[freddyolen]

it's a part of a front suspension of a car , but at this moment we don't know how it's been made. Most probably forged
It is something we didn't make ourselves

With the data you have provided, 6009, 6010 or 6011 meet that composition, according to Matweb.

freddyolen,

I think AlanD provided the right alloy type with 6010. I only checked EN 573-3 assuming that this was for a European application, and didn't check for US alloys in ASTM B 211. 6009 and 6011 are sheet alloys, so unless the part is a thin stamping/pressing, I would go with 6010.
