C35300 Brass Forgings | High-Leaded Brass | UNS C35300
C35300 Brass Forgings | High-Leaded Brass | UNS C35300
C35300 (UNS C35300), designated High-Leaded Brass, bridges the gap between C36000 free-cutting brass (maximum machinability) and C37700 forging brass (maximum forgeability). With 60.0–63.0% copper and 1.5–2.5% lead content (similar to CW617N/C37700 but slightly lower zinc), C35300 combines good hot forgeability with excellent machinability ratings of 80–90% (vs. C36000 = 100%). C35300 is produced as hot-forged blanks for screw machine stock, precision-machined electrical components, valve internals, and instrument parts where both forged density (no porosity) and high CNC machining productivity are required. It is specified in ASTM B124 and ASTM B283 for die forgings.

Applications
C35300 forged blanks and die forgings are used for: screw machine product blanks requiring forged grain structure; precision electrical component bodies (terminals, connector housings, fuse caps); instrument valve bodies and needle valve stems; lock hardware components; small actuator bodies; bicycle component hardware; automotive carburetor and fuel system components; watch and clock parts; and any precision CNC-machined part where forged stock density is required with high machining productivity.
- Screw machine blanks: bolts, nuts, fittings, inserts, standoffs
- Electrical: terminal bodies, connector housings, fuse caps, neutral links
- Instrument: needle valve bodies, gauge connections, pressure instrument bodies
- Lock hardware: lock cylinder bodies, deadbolt housings, padlock shackles
- Automotive: carburetor jet bodies, hydraulic union bodies, fuel fitting bodies
- General precision machined components requiring forged-density brass stock
