Help identifying aluminum alloy

Help identifying aluminum alloy

(OP)
I have been tasked with modifying a cast aluminum part and I am trying to match metals as closely as I can. I need to machine a new part to weld onto this casted part. Our metal scanner gave me a read out of:

alloy 1: 384/80/19

Zr 0.003 +-0.001
Ta 0.024 +-0.007
Fe 0.117 +-0.016
Al 90.648 +-0.401
Si 9.200 +-0.304

What off the shelf aluminum alloy best matches what I have?

Thank You for your help

RE: Help identifying aluminum alloy

Are you sure that there is no Cu or Ni in it?
This is a 4xxx alloy, so start looking there.

Since this is a cast alloy, I'm sure Ed meant to say it is of the 4xx.x series.

unless I send the part of for further testing, the reading are the best our scanner can pick up. Everything points to a 4,XXX series alloy, but not my main question is what alloy works best for welding to this piece?

RE: Help identifying aluminum alloy

To jseims,
Don't you know what your scanner's detection limits are? That will give good information about the presence of some other elements- its not likely it only detects Zr, Ta, Fe, Al and Si. I have not heard of scanner good with both the high atomic number and one low atomic number element.

You should have it sent to a lab for chemical composition testing.
