ASTM Standard Designation for C27200 Brass Tubing: ASTM B135
WINDO Brass Copper Ltd. carries with them a large inventory of C27200 brass tubing, a yellow brass that is both formable and machinable. C272 is only produced in tube form and is generally suitable for minimal corrosive conditions. The lead content prevents from successful welding, but common machine processes include: machining, forming, piercing, and punching.
