unknown alumiun composition

unknown alumiun composition

unknown alumiun composition

(OP)
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?

RE: unknown alumiun composition

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

RE: unknown alumiun composition

freddyolen,

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

RE: unknown alumiun composition

(OP)
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

RE: unknown alumiun composition

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.
