I scrounged some brass or bronze bar mystery metal from a dumpster when they were clearing out a college machine shop 15 yrs ago. But I honestly don't know whether I have brass or bronze. Any way to tell them apart?
I have a non-critical part I'd like to make out of bronze. Its a threaded flange. A hand crank will rotate a threaded steel shaft and the shafting thread will push/pull this threaded flange.
The oxidation is a dark brown. When I cut into the bar it is a brassy color. just ever so slightly redder than 360 brass. So perhaps this is brass and not bronze. Oh well, if the flange is brass or bronze it won't really matter.
But would like to make an educated guess on whether this stuff is brass or bronze. Any way I can be able to make an educated guess at this? Densitys look to be pretty close to each other.
