Default Restoring WW2 Engine...Need metal properties of NURAL aluminum...IDEAS?

Hey guys...

I am restoring a WW2 Diesel Engine...

We need to do some welding on one of the cylinders...but not 100% sure of the metal properties.

The company name "NURAL" is stamped into each...and from what I "recall"...Nural was a company name for DURALUMINUM (Dural).

Can anyone confirm?

Mike

Found this on google books, but it's probably not going to help you unless you know the number of the Nural alloy...

The best thing to do is find a ruined identical part and melt some it down to make filler rods for the welding process.
Your other option is to find specialist filler rods that allow for the welding of dissimilar types of alloys.

I cannot find a ruined part, as the engine is rare...

Here is a pic of the cylinder...maybe the markings on the right will help?

Nüral is a company name, indeed - Nürnberger Aluminiumwerke. I doubt it is the name of a specific alloy, because the company produced many different aluminum parts and these may not be all from the same alloy. So, I think it is just the name of the part maker. Most likely it is some ordinary aluminum alloy. A good aluminum welder would have many various rods of material, for various alloys. Just find an experienced one, working with expensive/quality material. He would know what to use. Or if not clear right away, would try a rod or two on some hidden spot and determine which one is the proper.

Duralumin is a sort of very light and solid aluminium generally used in the aircraft industry but I could be wrong.

Maybe a metallurgy laboratorium can help you? You could try the nearest technical university.

Good idea!
Try a local aluminum foundry they can be quite helpful if in the mood.

I have the idea any good machine shop should be able to guesstimate what rod will work best if shown the work.
