Key: * where used. From l<strong>at</strong>e 19 th century, electric melting methods were also in use in UK & are now the predominant technologies.<br />
C: certain, i.e., always expected L: likely P: possible T: trace only D: dependant on alloys under production<br />
Historic processes only, not used in ferrous foundries currently I: Iron foundries only S: Steel foundries only<br />
