im familar with lost foam, sand casting, die casting, forced mold casting, gravity die casting, plasma spray and few others...

the only process that might be able to duplicate this thing would be a forced mold casting in a vacuum....maybe??

using a steel mold then forcing the molten aluminum into the mold..

the problem comes in the abalation rings and the layer effect of the chads on the object..

my background covers almost 4 decades as far as various types of casting processes.

the whole problem in trying to make this thing would be the uniform layers with visable spaces under the chads or layering..

like i said...i dont know what it is, where it came from or what it could be used for.

all im saying is in my experience it would be near impossible to make in any casting process..

there are only so many ways to melt a piece of metal.

just using a bit of common sense.

the way i see it is if this was an accident how did it happen?? or for that matter where did it happen and what where they trying to make..

i certainly think there would be other examples of this to...they been around for 10 years or more an so far no one has shown anything like it or close to it in looks and if it can be made why hasnt someone made one??

here you go...it can be made just like this one. i bought his book and i saw him on the history channel...he dont have the education to make this thing...hes a former musician. 50 years in that business..hardly leaves time to make exotic alloy aluminum objects..lol

like i said before..the fact no one has shown another example of this metal makes it unusual to. dont you think?

everyone always thinks advanced life forms...who says they are so advanced?? if they excists at all. maybe they use the same things found on the planets that also make up our world...

just throwing out a few balls to see how they bounce.

aluminum is the most abundant metal on our planet and third after oxygen and silicone.

if this was ejected from some sort of craft "ours or theirs" it could very well be a power cell of some sort..

we are working on aluminum as a major power source now for hybrid cars. its considered the next major break out in battery technoligy.

its already a very reactive metal to other elements...it will generate a current with simple reactions to water or air or other elements used to alloy with it. you have a radioactive side that isnt naturally occurring so it could very well be used to power a reactor of some sort..

say you have a reactor that uses aluminum as a power source...you have heat. you have molten aluminum in the chamber, when the power is extracted you have an ejection of molten metal into the outside enviroment..

im just throwing out ideas.
