Why is copper used for drains?
One reason is because it resists corrosion and another reason is that it can easily be made into pipes for hot and cold water, oil, etc. However, compared to modern plastic materials, copper is much more expensive to use: its ore must first be mined, then the ore has to be smelted and refined into metal pipes, wires, etc. So nowadays, for drainpipes, plastic pipes are used instead of copper.

Pure copper has not been used to make British coins for about 150 years. From 1860, British "copper" coins were made from bronze which consisted mostly of copper varying from 95 to 97% copper. From 1992, British "copper" coins were made from copper plated steel. Ironically, copper is used to make modern "silver" coins (cupro-nickel) consisting usually of 75% copper and 25% nickel.
Why did miners think nickel was cursed?
During the late Middle Ages and Renaissance, miners digging for copper in the German region of Sachsen encountered ore that smelted into both that metal and a much harder silvery metal. Its hardness gave them so much difficulty that the miners thought it had been placed there by the devil.The new metal was soon called Kupfernickel, or "Old Nick's copper", using a slang name for the devil. When the Swedish mineralogist and chemist Baron Axel Fredrik Cronstedt finally isolated the substance in 1751 he simply eliminated "Kupfer" from Kupfernickel in the same way he had eliminated copper from the ore, giving the metal its modern name.
