Rm.{William Robotham - Chief Engineer}13/ML.17.7.40.

Herewith a copy of R.R. specification for brass which might do what you want.

I am also attaching a specification for cast phosphor bronze, which seems little better for it's mechanical properties than brass and is distinctly more susceptible to blow holes.
