YES, it is different than solid wire. Solid wire is copper and usually
plated with tin or solder so that it takes solder easily. Brass, if left
standing for any amount of time can acquire a coating of oxide which
resists solder adhesion. And most electronic fluxes are not formulated
to handle this. You would have to scrupulously clean the brass
immediately before inserting it and soldering it if you want reliable
connections. I have a lot of experience with brass that was "soldered"
to PCBs.
