Yes, brass can be soldered to copper using a soldering iron and appropriate soldering techniques.
Take either an SOS pad or a wire brush and rough up both the inside of the brass fitting and outside of copper pipe, put the copper pipe into the fitting and solder around it.
No, pure brass is difficult to solder with plumbing solder because it has a high melting point and poor wettability with typical lead-based solders. It is recommended to use an appropriate flux and solder with a higher silver content for better adhesion and conductivity when soldering pure brass.
Yes, you can either solder them or fit mechanical (threaded) fittings.
*Yes you can solder brass, as long as it isn't the decorative polished brass. They have used brass fittings in plumbing for years and years. It has the same characteristics as copper.
Brass is an alloy of Copper and Zinc. Originally solder is an alloy of Tin and Lead. Lead-free solders in commercial use may contain tin, copper, silver, bismuth, indium, zinc, antimony, and traces of other metals.
Certainly look up Flagg Flow T.P Fittings T.P thread-less copper fittings will FIT on schedule 40/80 /120 Brass pipe Ideally it should be brazed but soldering will hold domestic water pressures Also many solder fittings ARE CAST BRASS rather then wrought copper
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
An example of a solid dissolved in a solid is brass, which is an alloy of copper and zinc. In brass, the atoms of zinc are dissolved into the solid lattice of copper, forming a homogeneous solid solution.
Any pipe dope will work but Teflon tape is a lot cleaner.
Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
Always and only solder.
You should use solder, not brazing. Brazing is used to join iron or steel products together.
