Weights: Iron vs Steel vs Ceramic

[heiroglif]

I have weighed a cast iron brake disc and got an average reading of roughly 4kg, id like to know how a stainless steel disc would compare with this weight (just roughly) and also, if a ceramic plate was added to the iron disc...any help appreciated...thanks!

The average density of most stainless steels is around .28 Lbm/in3

hi, thanks for your reply,

im just looking for some predictions in kg,

if a cast iron disc with diameter 0.3m weighs 4kg, then how would a stainless steel disc of the same size match up to that?

also how much extra weight would a ceramic plate added to the cast iron disc give?

i took the weight of the iron disc, can't find a steel and ceramic disc, so anyhelp would be great...

thanks

Work out how much volume the steel and ceramic discs would be, multiply each of those values by its density, and you have the weight of the disc.
