Aluminium 4045 mechanical properties

Aluminium 4045 mechanical properties

Aluminium 4045 mechanical properties

(OP)
Hi Guys

I'm struggling to find and published data on Aluminium AA4045

I specifically need the Tensile strength figures, can anyone assist?

Thanks in anticipation of your help.

RE: Aluminium 4045 mechanical properties

I would expect it to mirror the properties of casting alloy 443: 17ksi min uts; 3% min. %E.

RE: Aluminium 4045 mechanical properties

I would not expect a cast AL be the same as bar stock.  It sould be be much stronger.

RE: Aluminium 4045 mechanical properties

Yeah, well an aluminium bar alloy with 10 % by mass Si is going to have limited ductility, hence, limited strain hardening, and hence, limited strength.

RE: Aluminium 4045 mechanical properties

AA 4045 (aluminum-10% silicon)is welding wire. Welding is basically localized casting. Therefore, when you are done, you have cast metal mechanical properties, thus my reference to casting alloy 443, an aluminum silicon alloy. In its intended use as welding wire, the final properties of the joint are what needs to be taken into account, rather than the tensile properties of the 4045 itself, which why you don't find properties published for this material.

Thanks for the info so far.

To give you an insight as to why I need the tensile strength of 4045;

I working on a unit that has 4045/3003/4045 clad plate involved.

In order to qualify the plate for use in a CatIV pressure vessel I need to do Tensile tests on the Pre-Braze material and I need to know how much strength the 4045 Clad contributes to the total strength of the Test piece.

RE: Aluminium 4045 mechanical properties

You need to perform your own tension testing if this is for a pressure vessel.

And now we get "the rest of the story" as Paul Harvey would say.

Sorry Swall, I expected this to be a reasonably straight-forward request but I am grateful of your reply.

To CoryPad, I'm fully aware of the requirements for Tensile Testing, however we are faced with 7 tons of Clad sheet without any testing being done prior to the cladding.

Stangely enough, it's the performance of the 3003 that we're interested in, The question being asked by the 3rd party inspector is; does the 4045 contribute to the strength of the 3003 component, should it be included or should it be ignored.

Given the reply from Swall plus some further data from the material supplier it was fairly simple to discount the 4045 component at this stage of the manufacture.

RE: Aluminium 4045 mechanical properties

I still don't see why you don't conduct your own testing.  Do some tests with the sheet as-is, and some with the cladding removed.

The high Si concentration could initiate cracking of the 4045, which could be tranferred to the 3003 core.

Cory
