Malleable iron is much stronger and less brittle under tension and this makes it excellent for thin items and moving parts such as hinges and gate latches. Malleable iron is basically cast iron which has had an extra special heat process added to it during it’s production. This ‘annealing’ process gives the iron malleability (hence the name malleable iron). This makes the iron much stronger and gives it a slight elastic property which, unlike cast iron, stops it from being brittle. Stopping c
