370 Low Lead Brass Machined Parts

Manufacturers that need forged brass hardware finished to precise, machined tolerances often run into a tradeoff between forgeability and machinability. 370 low lead brass machined parts remove that tradeoff. 370 brass, also known as C37700 forging brass, is engineered with reduced lead content and tight chemical controls that support excellent hot-forging behavior alongside strong machinability once the part is formed.

E.J. Basler provides 370 brass machining services for production runs of 100,000 pieces and up, finishing forged blanks to the tolerances your drawings call for.

Properties and Benefits of 370 Low Lead Brass

370 brass is formulated for excellent forging characteristics, with tensile strength ranging from 45,000 to 63,000 PSI and yield strength from 20,000 to 28,000 PSI depending on section size. Its reduced lead content keeps corrosion resistance high while still providing enough machinability to finish forged parts to tight tolerances.

Key benefits of 370 low lead brass:

  • Excellent hot-forging behavior for complex, near-net shapes
  • Good machinability for finishing forged blanks to tight tolerances
  • Tensile strength up to 63,000 PSI depending on section size
  • Good corrosion resistance for plumbing and outdoor hardware
  • Readily recyclable
  • Cost-effective for production volumes of 100,000 pieces and beyond

Applications of 370 Low Lead Brass Machined Parts

370 brass screw machining finishes forged components across plumbing, marine, and industrial hardware, wherever a forged blank needs threaded features or tight-tolerance surfaces. Common applications include:

  • Forged valve bodies and stems
  • Plumbing fittings and couplings
  • Marine fittings, valves, and pump components
  • Architectural and lock hardware
  • Fasteners: screws, bolts, nuts, and washers
  • Automotive fittings and connectors
  • Hose and pipe couplings
  • Gas and water meter components

Frequently Asked Questions

What makes 370 brass different from standard forging brass?

370 brass is formulated with tight chemical controls and reduced lead content, which preserves strong hot-forging behavior while still delivering enough machinability to finish forged parts to precise tolerances.

Can 370 brass parts be machined after forging?

Yes. 370 brass is specifically engineered to combine excellent forgeability with good machinability, so forged blanks can be turned, drilled, and threaded to finished tolerances without switching materials.

What tolerances can E.J. Basler hold on 370 brass machined parts?

On Hydromat, Swiss, and Davenport platforms, we routinely hold tolerances within plus or minus 0.0005 inches on finished features. Tighter tolerances are available with secondary grinding operations.

Is 370 brass a good fit for plumbing and marine hardware?

Yes. Its corrosion resistance and forgeability make 370 brass a common choice for valve bodies, fittings, and hardware exposed to water and outdoor conditions.

Can E.J. Basler handle production runs under 100,000 pieces?

Yes. While our high-volume contract manufacturing center is built for runs of 100,000+ pieces, we also accept smaller production volumes when the part fits our process strengths.
