Exposure to air or oxygen causes the brownish film on copper piping. Water - especially mineralized water - causes greenish or bluish corrosion. And deionized water can pull copper metal from the piping and cause pitting or damage.
The term "rusting" is reserved for the corrosion of iron.
Copper does not rust. Rust is a mixture of hydrated iron oxides so, by definition, if will only form on iron and iron-rich materials (such as some types of steel). Copper can get a covering of Verdigris, which is a green-colored compound.

∙ 11y agoUnlike iron when exposed to moisture, copper does not corrode fully when it oxidises. Instead, it reacts with oxygen over time to form a layer of copper oxide which protects the bulk from corrosion. Older copper often develops a layer of green verdigris (called patina).

What causes rust on copper?
It's probably oxidation, not rust.
Which metal rust fastest copper bronze or steel?
iron will rust faster because the hydrogen molecules combine with metalic molecules in the iron faster which causes the chemical reaction process to speed up sincerly, Jake from AZ 7th grade student

How do you do the experiment 'Which metal rust fastest copper bronze or steel?
i dont know of an experiment to test this but copper will not rust, and bronze being comprised of tin and copper, the answer to which will rust fastest is steel. I hope this helps you.
What can cause copper on the exterior of a house to have a red rust appearance?
Most likely some other object has dripped rust onto the copper, which can be removed. Copper does not rust, but it does form a green patina over time.
