What C360 brass bar stock is
C360 (also called "free-cutting brass" or H62) is a leaded yellow brass — ~61% copper, 36% zinc, 3% lead — with the highest machinability rating (100%) of any copper alloy. Bar is supplied per ASTM B16 in round, square, and hex profiles. Common downstream: turned fittings, valve bodies, pneumatic components, electrical contact pieces, and any high-volume screw-machine work where surface finish and chip control matter.
What to look for in a supplier
C360 is a screw-machine commodity — most non-ferrous distributors carry it. Differentiators: temper (1/2 hard is most common for general turning; soft for severe forming; hard for higher strength), profile range (round bar from 0.0625" through 4" is standard; hex sizes for fittings like 1/2" hex are heavily stocked), and tolerance (precision-drawn for tight-tolerance turning, mill-drawn for general work). Lead-free variants (C36000-LF / EnviroBrass / EcoBrass) are increasingly required for potable-water and food-contact applications — confirm regulatory compliance if applicable.
FAQ
Common questions
What's the machinability rating of C360 vs. other brasses?
C360 has the highest machinability rating among commercial copper alloys at 100% (the baseline). C385 architectural brass is around 90%, C260 cartridge brass is 30%, copper itself is 20%. For high-volume screw-machine production, C360 is the standard choice.
What's the difference between C360 and C385?
Same family, slightly different chemistry — C385 has less lead and more zinc, giving better forming/extrusion behavior. C360 is the screw-machine standard; C385 is more common in extruded architectural shapes (rails, trim). For bar stock, C360 is what you want.
Is C360 brass food-safe?
C360 contains lead, so it's not approved for direct food or potable-water contact under most current regulations. For drinking-water fittings and food-contact components, use lead-free brass (C69300, EnviroBrass, EcoBrass — various proprietary low-lead grades). Confirm regulatory compliance before specifying for these applications.
What sizes does C360 brass round bar come in?
Stocking distributors carry round bar in fractional sizes from 1/16" through 4" in standard increments. Hex bar is most common in fitting sizes (1/4", 3/8", 1/2", 5/8", 3/4", 1"). Square bar is available but less commonly stocked.
