Amber Copper = Yes Brass = No, although it has been used and there is a difference of opinion in various factions. If getting into building live steam boilers, one thing you'll need to learn and that's "silver soldering" (it's actually brazing because of the temperature involved); so-called "soft soldering" that you may be familiar with won't work in live steam.
