Why Non-Ferrous Metals for Turned Parts?
Non-ferrous metals like brass, copper and bronze are among the best machinable materials. Brass (CuZn39Pb3) is the classic for screw machine parts: short chips, high cutting speeds and excellent surface finishes. Copper excels through its electrical and thermal conductivity, bronze through wear resistance and sliding properties.
On our Traub TNL 32 (up to Ø32 mm) we manufacture brass turned parts in large series, on the DMG MORI NLX 2000 (up to Ø300 mm) also larger copper and bronze components with complete machining.
Non-Ferrous Metals Overview
We process all common brass, copper and bronze alloys. The choice depends on function, conductivity, wear requirements and corrosion resistance.
CuZn39Pb3 (Brass)
Free-cutting brass: Outstanding machinability, short chips, fast cycle times. The standard material for brass series turned parts.
CuZn37 (Brass)
Lead-free brass with good formability and corrosion resistance. For drinking water applications (EU directive) and decorative parts.
Cu-ETP (Electrolytic Copper)
Pure copper with 99.9% Cu. Highest electrical and thermal conductivity. For busbars, contacts and heat exchangers.
CuSn8 (Tin Bronze)
Wear-resistant bearing bronze. Good sliding properties, high load capacity. For bushings, plain bearings and gears.
RG7 (Gunmetal)
Corrosion-resistant copper-tin-zinc alloy. For fittings, valve bodies and pump parts. Seawater resistant.
CuNi12Zn24 (Nickel Silver)
Silvery-white copper-nickel-zinc alloy. Good corrosion resistance and decorative appearance. For fittings and instrument parts.
Benefits of Non-Ferrous Turned Parts
Outstanding Machinability
Brass is the reference material for machinability (100% per ISO 3685). Short chips, high cutting data, short cycle times.
Electrical Conductivity
Copper has the highest conductivity of all engineering metals at 58 MS/m. For contacts, busbars and electronics.
Sliding & Wear Properties
Bronze alloys are ideal bearing materials. Self-lubricating properties reduce maintenance effort.
Corrosion Resistant
Brass and bronze resist many media, gunmetal is even seawater resistant. No additional coating needed.
Decorative Appearance
Golden brass shine, reddish copper or silvery nickel silver — non-ferrous metals also offer visually attractive surfaces.
Lead-Free Available
For drinking water applications we supply lead-free brass alloys per EU directive (CuZn37, CuZn42).

Questions about Non-Ferrous Parts
Q1Which non-ferrous metals do you process?
Brass (CuZn39Pb3, CuZn37), copper (Cu-ETP, Cu-OF), tin bronze (CuSn8), gunmetal (RG7/RG5), nickel silver (CuNi12Zn24) and special bronzes. Further alloys on request.
Q2Why is brass ideal for series turned parts?
Brass CuZn39Pb3 has outstanding machinability due to its lead content: short chips, high cutting speeds and very good surface finishes — up to 50% shorter cycle times than steel.
Q3Do you offer lead-free brass?
Yes — for drinking water applications and EU-compliant products we use CuZn37, CuZn42 and other lead-free alloys per EU Drinking Water Directive.
Q4What surface finishes do you offer for brass turned parts?
Nickel plating, chrome plating, gold plating, tin plating, polishing and glass bead blasting. Brass is particularly well suited for electroplating.
Q5How much do brass turned parts cost?
Brass series turned parts are very economical due to short cycle times — simple parts from approx. €0.50–2/piece in series. Copper and bronze are more expensive due to material costs. We calculate on a project-by-project basis.
Q6Is copper suitable for CNC turning?
Yes, but copper is softer and produces long chips. With adapted cutting edge geometry and feed rate, we manufacture copper turned parts in high quality — e.g. busbars and contacts for electrical engineering.
Q7What applications is tin bronze CuSn8 suitable for?
CuSn8 is the classic bearing material: High wear resistance, good emergency running properties and corrosion resistance. Ideal for bushings, plain bearings and worm gears.
Q8What is the minimum order quantity?
From 1 piece. However, brass turned parts are particularly economical from 100+ pieces, as the short cycle times quickly amortize the setup costs.
