If you are using a blueprint that calls for multiple types of alloys (indicated in parentheses in the ingredient list with the number of types required and the amount needed of each type) you can choose from Cobalt Ingot, Copper Ingot, Iridium … Tin and copper are relatively soft metals that will deform on striking (though tin to a lesser extent than copper), but alloying creates a metal which is harder and less ductile and also one with more elasticity than either of the two metals. Bronze is still commonly used in ship propellers and submerged bearings. Iron Age: Iron is the other metal, which gained supreme industrial importance in history. The tin bronzes are used in bearings, gears, piston rings, valves and fittings. 1693 May, Thomas Povey, “I. Bronze, or bronze-like alloys and mixtures, were used for coins over a longer period.
