Is it safe to use copper tubes for a brake line?
My stock brake line had some nasty rusty patches in places, so it gave a leak. I want replace a part of it with a 3/16 copper tubes (0,9mm thick). Will they withstand pressure? Are there any successful examples?

Well, I came across on that article from science direct. http://64.90.169.191/applications/automotive/brake.html
It says copper/nickel 90/10 alloy is the best choice.

Copper alloy as someone already mentioned. It will last forever, it's cheap, and its generally available from your local autozone. Most OEMs use them for a reason.
Stainless steel would be incredibly difficult to work with unless you mean braided stainless lines. The burst pressure of copper vs stainless as far as hardlines goes is about the same. You'll never see 5000+psi so it doesn't really matter.

The nickle copper brake line material is extremely safe to use for brake line as that is one of the purposes it was designed for. Do not use pure copper line as it may not be of sufficient pressure rating and may rupture under hard braking pressure. It is also not corrosion resistant. It will work in a pinch but buy a good grade of material. Stainless lines are also a good option but are harder to work with. If making the lines yourself you will need a bender and flaring tool.
