What is the fusing metal? Lead? Aluminum?

It aint aluminum cuz it melted at around 300'F. Not lead, cuz toxic. My guess is some bismuth / antimony eutectic alloy - but have not tested. But the part came, and fixed my pressure cooker !

The inserts are made of metal. Whether it's steel or Aluminum I don't know. I gave it away as a gift.

It is to melt lead. Sometimes the lead can have other metals in it that can be melted together. Just make sure the metal is clean and moisture free. Should melt other kinds of metals too if they are soft enuough

Wires have all been made of copper for the past 50-60 years. Prior to that there have been different mixtures involving aluminum but there's no such thing as being incompatible just because its a different metal.

Metal. FYI, the assembly is painful as there are many, many pieces, took us 3 hours to put together and I've done lot's of building things in my lifetime. We're only buying fully assembled products moving forward :-)

Only used aluminum, but I was disappointed the set didn't come with a few rivnuts. Set works great, though!

All aluminum. Aluminum male end slides into aluminum female end, with a spring loaded metal clip that holds them together. From my experience, it is more than sturdy, and I had no worries about it breaking or coming apart.

None of above. It's a fairly soft metal, almost like lead. It will hold up to do exactly what it was designed to do , but will not tolerate much flexing, over tightening of screws, etc.

I guess It's Aluminum. Fits well on Prestige Cooker.Why bother? It'll melt when pressure is high as safety measure.

Aluminum with a nonstick coating. Magnet won't stick and not a ceramic or plastic.

My guess is poly. Its pretty stiff. But does help the metal on metal "clinging"

I think it will melt tin, as that is often part of solder (lead solder). Aluminum has a higher melting point this unit cannot reach.

Metal..they're supposed to snap in but some don't align so you can just duct tape them

Not being a metallurgist, I cannot say for sure, but it appears to be nothing but stainless steel. The aluminum looks to be entirely sandwiched in the base and not exposed anywhere.

Best I can tell aluminum. At least the shaft that goes into the rivet gun is aluminum. Don't know about the expanding part.

Negative. A magnet will not stick to the bottom, so I'm assuming its aluminum.

It is silver and non-magnetic, so I'm going with aluminum. Can't answer the other half of your question, I know aluminum can oxidize ...
