My first thought is, thats funny, but heres goes. Youre probably
better off figuring out what your metal is approximately, and then
looking up the properties. Mechanical testing, by a novice, with only
one ingot, using a makeshift setup is going to give you junk for
results, but you can always try. Tensile strength is not too
challenging as long as you can prepare a decent specimen. At the very
minimum some sort of hydraulic press, that you could rig to stretch a
sample, with a pressure gauge would be essential and additionally the
ability measure elongation would give you strain to failure & %
elongation ( a simple micrometer/caliper would work). You would have
to have the ability to attach the specimens in some kind of secure jaw
and prepare a nice neck to make sure you sample breaks where you want.
You will need a micrometer to measure the fracture surface area to
determine your stress to failure (load / area) and then you are set.
See what you can get with tensile strength, dont bother with the shear
Here is an example of a typicaly tensile testing setup using sample
