Specification-led brass supply
Naval brass C46400 is a copper-zinc-tin alloy commonly used where higher strength and resistance in selected marine or cooling-water duties are required.
Standard C46400 may contain lead up to the applicable grade limit. If a project requires lead-free, RoHS or REACH documentation, identify that requirement at enquiry stage and obtain written confirmation.

C46400 is a copper-zinc-tin alloy commonly designated CuZn36Sn1Pb or CW712R. ASTM B111 is a common tube specification.
The standard grade may contain lead within its chemistry limits. State any lead-free or regulatory requirement at RFQ stage; it must be separately confirmed.
A published reference range is 6–101.6 mm OD, 0.71–3.25 mm wall and lengths up to 12 m. Final availability depends on condition, form and quantity.
No. C46400 and C44300 have different chemistry, strength and typical uses. Follow the OEM or engineering material specification.
