A general term for cheap, soft alloys usually lead or copper based and used for simple castings.

This can happen in modern coins that have cheaper alloys that do not retain their crystal structures when heated.

This ensures that you are buying genuine silver and not a cheap alloy.

Indeed, the relatively high cost of nitinol has led some manufacturers to use cheaper, copper-based alloys.

No trace of source of this cheap alloy which is virtually synthetic gold.

Its relatively high cost limits its use to applications where cheaper alloys are not suitable.

It is a cheap malleable alloy mainly used for medals, ornament, decoration and some munitions.

Originally made from tin, now they are made from cheaper low-melting alloys based on lead.

"That is correct," said the old man "The practice stopped when cheaper alloys were introduced, which could be applied to the same purpose."

These blocks were metal, made of a cheap alloy of commoner substances like zinc or iron, perhaps even lead.
