60/40 Rosin Core, 1 lb Spool, contains lead alloy.

Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. Kester 44 Rosin Flux has virtually dominated the field of activated rosin core solders for well over four decades.

An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering.

Features

  • Classified as ROM1 per J-STD-004
  • Excellent solderability to a wide variety of metallizations
  • High activity RA formulation
  • Industry standard RA cored wire for decades

Yes, 60/40 is the tin to lead ratio. Check out the specification sheet in the Specifications, Files, and Documents for the full description on the flux type. Many people use this as an all purpose solder for soldering wires and pcb's. It will work well with the wires you listed.

Good Stuff - Seems like solder is not easy to find anymore, so I'm happy to see this is available and works like it should.

You won't find a better solder for amp and guitar circuits! It flows extremely well and the melting point is perfect. Don't waste time or money with anything else.
