Copper is relatively light weight, hard to crack, and solders beautifully when attaching fittings.

Steel is heavier, and cannot be soldered, so all fitting are threaded.

Both types of pipe material are getting fairly expensive, so many water pipes these days are made of polypropylene plastic.

In fact, iron is only used for large size pipes . . . usually underground, but not always. Most modern underground pipes are made of PVC, or polyvinyl-chloride.

ABS or acrylo-nitrile-butadiene-styrene is often used for non-pressure pipes like drainage pipes, for instance.

I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.


What happen when copper sulphate is stored in iron vessel?

Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
