What Is C35600 Extra High Leaded Brass?
C35600 is a copper-zinc-lead alloy belonging to the wrought brass family. It contains approximately 2.0–3.0% lead, which substantially improves its machining characteristics compared with many lower-lead brass alloys.
The lead phase contributes to chip segmentation during cutting operations, helping manufacturers achieve efficient machining, consistent dimensional control and reduced tool loading under appropriate cutting conditions.
C35600 is also commonly referred to as engraving brass because it can produce clean, detailed machined surfaces suitable for nameplates, plaques and precision decorative hardware.
Unlike phosphor bronze, which is primarily based on copper, tin and phosphorus, C35600 is a copper-zinc-lead alloy developed for applications where machinability is a major material-selection requirement.

Role of Alloying Elements
Copper (Cu)
Copper provides the primary metallic matrix and contributes to thermal conductivity, corrosion performance and the characteristic appearance of the alloy.
Zinc (Zn)
Zinc modifies strength, hardness and manufacturing characteristics. The copper-zinc balance influences the alloy's microstructure and forming behavior.
Lead (Pb)
Lead improves free-cutting behavior by promoting chip segmentation and reducing resistance during machining.
However, the lead content requires careful evaluation where environmental, occupational or product-specific regulations apply.

C35600 Machinability and Manufacturing Characteristics
One of the principal advantages of C35600 brass is its excellent free-cutting performance.
Its high lead content promotes chip breakage during machining, helping manufacturers process components with complex geometries and tight dimensional requirements.
CNC Turning
C35600 is suitable for machining cylindrical components, including threaded fittings, bushings, precision hardware and other turned parts.
Under suitable machining conditions, the alloy supports efficient chip formation and consistent surface finish.
Drilling and Boring
The alloy's chip-breaking characteristics are advantageous in drilling and internal machining operations.
Hole tolerances and internal surface quality depend on tool geometry, cutting conditions and inspection methods.
Threading and Tapping
C35600 can be used for machined internal and external threads.
For threaded components, buyers should specify thread type, pitch, tolerance class and inspection requirements.
Milling and Engraving
C35600 is suitable for engraving and milling operations used to manufacture nameplates, identification plates, decorative hardware and precision mechanical parts.
Cold Forming
Cold-forming performance is more limited than that of many low-lead brass alloys.
Where bending, severe swaging, flaring or other forming operations are required, the temper and manufacturing sequence should be evaluated before material selection.
Joining and Welding
| Process | General Suitability |
|---|---|
| Machining | Excellent |
| Soldering | Excellent |
| Brazing | Good |
| Polishing | Good |
| Cold Working | Poor |
| Hot Working | Fair |
| Conventional Fusion Welding | Generally Not Recommended |
Important: Conventional fusion welding is generally unsuitable because lead can contribute to cracking and other weld-quality problems.
For assemblies requiring joining, soldering, brazing or mechanical fastening should be evaluated against the application requirements.
C35600 Corrosion Resistance and Application Limitations
C35600 brass offers useful corrosion resistance in many indoor and atmospheric environments.
Its performance, however, depends on exposure conditions, mechanical stress, operating temperature and the surrounding chemical environment.
Suitable Environments
C35600 may be considered for components used in:
Indoor industrial equipment
General mechanical assemblies
Dry atmospheric environments
Decorative hardware
Controlled industrial operating conditions
Potential Corrosion Risks
Dezincification
In certain aggressive aqueous environments, zinc may be selectively removed from brass, weakening the remaining material.
Stress Corrosion Cracking
Brass alloys may be susceptible to stress corrosion cracking in environments containing ammonia or certain amine compounds, particularly when tensile stresses are present.
Chloride-Rich Environments
Exposure to seawater or aggressive chloride-containing solutions requires careful evaluation.
Lead-Related Restrictions
C35600 contains approximately 2.0–3.0% lead and should not be described as lead-free.
It should not be selected as a wetted material for regulated drinking-water applications without a specific, documented compliance assessment.
For corrosion-sensitive applications, material selection should be reviewed against the actual service environment rather than based on the alloy designation alone.
C35600 Leaded Brass Applications
C35600 is primarily selected where precise machining, good surface quality and efficient component production are important.
1. Precision CNC Machined Components
C35600 brass rods and bars are suitable for manufacturing precision-turned and milled components.

Applications include:
Industrial nameplates
Engraved identification plaques
Equipment labels
Decorative metal hardware
4. Clock, Lock and Instrument Components
C35600 can be used for accurately machined components in mechanical instruments, locks and related assemblies.

Potential applications include furniture hardware, equipment fittings and other components requiring good machinability and surface finish.
6. OEM and Custom-Designed Parts
For custom manufacturing projects, C35600 can be supplied as raw material for subsequent CNC machining, milling, engraving and other secondary operations.
Buyers should provide technical drawings to confirm the required material form, temper and dimensions.
C35600 vs C36000 vs C35300 Brass
Selecting the correct free-machining brass grade depends on material composition, component geometry, mechanical requirements and applicable regulations.
