Metrology Material (liquid metal) Cerlo or Sirlo sp?

[Buckshott00]

Hello all,

I was hoping someone could help me. I am looking for the name of a liquid metal alloy. It is used in metrology. It is solid (mostly) at room temp, but if you place it over a heat element, it becomes liquid.

It's great for holding tolerance and checking ID grooves and such. I don't know its proper name or where to find the stuff. It would sometime get a film over the top when in the crucible over the heat element. It's not a lot of heat either. This stuff sets fast.

It's kind of like a liquid metal version of reprorubber.

Do you mean Cerro Low?

Thanks RP!

I am pretty sure that's the stuff.

We used to use it for proof casting.

We used to keep it over a lightbulb heat source all day. I guess it says not to do that, but it was always accurate enough
