2002 Aluminum Cylinder Head Alloy

[RogerRamJet77]

Mike,

 

Checking the grain structure is an option, however, I do not think it will tell you the percentage of the elements in the alloy.  I know of a couple ways to find the percentages; first, take a sample to a lab with a scanning electron microscope or second, take the head to a lab with an x-ray florescence alloy analyzer.  Both methods can provide a percentage of elements in the alloy.  Some x-ray florescence alloy analyzer is portable, so you do not need to cut off a sample.

 

Regards,

Roger

The welding rod used was 4043.

Other options are "possibly" 4643 or 4943.

Neither of which were used on this project but will be tried out in the future.

M20 Heads were either of these depending when and where they were cast 

Al Si 6 Cu 4

Al Si 8 Cu 4

Al Si 6 Cu 3

Al Si 10 Cu 2

Rumours say that M10 Heads might be
Al Si 9 Cu 3

 

I think they all can take the same heat treatment

Interesting project, Don. What are your HP goals ?

Being versed in the phillips 300 and 600 em's ( it is a long story) I would vote for x-ray Fluorescence.

I shudder to think of how many Canuck pesos I would need to lay out in order to have one in my tool chest.

Probably aboot 4 grand in USA shekels now. Here's Steve pointing the gun at me in front of a chrome ore pile in Oman. And a pic of the readout when I pointed it at my antique rose gold ring....

I rarely join forms. The participants here have on the whole been exceedingly helpful. If you have or are involved with a fast vintage car. Wonderful be proud of your work and accomplishments. Much of what I did in my 46 year Professional career as an engine and cylinder head specialist is now Vintage. This included Winston Cup, CART/Indy Car, IMSA GTP (Class C in Europe), F-5000, etc., etc., etc.

Thank you to the members who answered my cylinder heads material question. What I learned from the form members was passed on to the Metallurgist who assisted us with the vintage Porsche head project which will be available next year.
