300: 25: 189:"Tungum is an alloy discovered by a well known metallurgist from whose name the alloy is derived. Experimenting with a view to finding a combination of metals suitable for a special purpose he had in view, he produced a compound which is known as TUNGUM. Recognising that its close likeness to 22 carat 181:, Sidney Tungay, a metallurgist, was experimenting with a new copper-based alloy which he hoped would look like gold when polished and which would be durable in everyday use.
