What is this?

[Meissner]

Found by my parents in Goldfields area Western Oz, sitting ON the ground, not under.

What I know about it;

Reasonably soft, can be marked with steel scissors easily.
Not Magnetic
Not surprisingly heavy/light for it's size
A small piece was melted to a soft blob with a gas torch, but not puddled.
Glowed orange when "melted" (ergo, not aluminium)

Last image shows the place where I removed a chunk for melting in a crucible, shows very silver inside.

I've searched for hours online for various elements/minerals to find a match, but to no avail.

Elements I think it is NOT (but I could be wrong).

Aluminium
Magnesium
Tin
Cadmium
Silver

Any Ideas?

Lead?

Chrondite meteorite maybe hard to tell

Not heavy enough to be Lead, also lead doesn't glow when melted.

It's not a meteorite of any sort I've seen, too ragged for anything that would have passed through the atmosphere.

White metal, used for bearings on gold stampers and other related machinery.

Some of the metals that make up a white metal alloy are antimony, tin, lead, cadmium, bismuth, and zinc. Not all of these metals are found in all white metal alloys but are mixed to achieve a desired goal or need.

Looks like an alloy of some sort.

 

[Meissner]

After further testing, we think it is likely an alloy of Aluminium, magnesium and possibly titanium.
