cast alloy question

[grommit]

please can anyone help me, my Royal Enfield Bullet's main parts are painted tubular steel and alluminium....but what throws me is my friend keeps saying its cast alloy... an alloy is a combination of 2 or more metals in my eyes?? can you help with what he means,it just confuses me with so many metals and variations out there.
many thanks
brian

all processed metal not in raw earth form is an alloy so dont let that term fool you. as for your bike i cant say since i have never owned an enfield before but the frame components should be mild steel and the engine/trans should be aluminum castings, as well as the front fork lowers. the fork uppers will be hard chromed steel. the engine cylinders (where black) might also be a cast steel but i am not for sure. i hope this helps to clear some of the confusion.
