  • I do know that zinc makes healthier sperm.  Copper not so much.  That's all I got.

  • Zinc is a brittle and heavy metal that is highly reactive  with oxygen and doesn't form any protective oxides. It also has poor electrical conductivity compared to copper. This makes zinc about as useful for electrical transmission as  copper is for galvanic protection of iron.

    They use zinc in some roofing applications. You've seen those ugly stains on asphalt roofs------ that is a form of algae growing there. If you have zinc strips applied to the peaks of your roof, or manufactured into your next set of shingles, the zinc slowly 'melts' down across the entire roof, killing the algae.
