So I'm installing 1/2 and 3/4 copper water pipe, city water, ~60psi.
Question - how much can you safely bend the pipe without risk of future
failure?

More important is the type of bender you use. Depending on the radius, it
can go 180 degrees. A slight kink though, can cause damage to the wall and
failure.
