Casting under pressure

hi jens,
tim is far more knowledgable about this than i, given his profession. but, i think modern bronze (ie the type bought in bulk from art suppliers) is made of an alloy that is much harder than 'old bronze'. i believe it is silica and i saw an artist try and file the bronze by hand and it was almost untouchable. i know i have filed down blade edges with much less effort. I have a feeling it could be even harder than steel.
