IF you want to find what a heater core is made of and you don't just want to cut it up and see, Go archimedies on their ass.
The heater core is either all-brass or copper brass. either way the two alloys weigh slightly differntly (the bigger the heatercore) the bigger the wight difference. (this is ignoring soldering and such)
And now you shove it in in a mesauring bucket (you make a bucket with a "ruler" down the side showing how much water is in it. you mark where the water was before and where it was after, after all the ait bubles have be displaced. yiu'll be able to find its volume.
With its volume/weight you should now be able to work out its density. and hope that you can get an acurate enough reading.
given that Brass's density is 0.309 lb/in^3
and copper is 0.322 lb/in^3
Then any reading betweeen the two values will show that a mixture of copper and brass are present. closer to the brass end of the scale and we have mainly brass.
Sorry I could not get metric readings.
