What Is L63 Brass (Л63)?
L63 brass is a Russian copper-zinc wrought alloy containing approximately 62–65% copper, with zinc forming the balance. It is commonly classified as an engineering yellow brass suitable for forming, stamping, rolling, drawing and general fabrication.
The low permitted lead level helps L63 brass retain good cold-forming characteristics. Its balance of strength, ductility, appearance and corrosion resistance makes it suitable for sheet-metal components, decorative parts, tubes, wires and general engineering products.
L63 brass properties vary according to product form, dimensions, manufacturing method and delivery condition. Annealed material generally provides greater elongation and formability, while harder conditions provide increased tensile strength and dimensional stability.
Main Characteristics of L63 Brass
- Good cold-forming performance
- Suitable for stamping and deep drawing
- Good corrosion resistance in normal environments
- Attractive yellow-brass appearance
- Good brazing and soldering characteristics
- Suitable for rolling and wire drawing
- Available in annealed, half-hard and hard conditions
- Good surface finishing and polishing performance
- Reliable strength for general engineering applications
What Is LS59-1 Brass (ЛС59-1)?
LS59-1 is a Russian leaded brass grade containing approximately 57–60% copper and 0.8–1.9% lead, with zinc forming the balance.
The controlled lead addition improves chip formation, cutting performance and machining efficiency. LS59-1 leaded brass is therefore frequently selected for components produced through turning, milling, drilling, threading and CNC machining.
Compared with L63, LS59-1 generally provides better machinability but lower cold-forming capability. It is particularly suitable for precision components, fasteners, bushings, valve parts, fittings, gears and other products that require repeatable machining and a clean finished surface.
Main Characteristics of LS59-1 Brass
- Good machinability
- Improved chip-breaking performance
- Suitable for CNC machining
- Good hot-working and forging capability
- Suitable for turning, milling and drilling
- Good dimensional accuracy after machining
- Reliable strength for engineering components
- Good surface finish after machining
- Suitable for threaded and precision components
L63 Brass Chemical Composition
The following L63 chemical composition values are expressed as percentages by mass.
| Element | L63 Composition |
|---|---|
| Copper, Cu | 62–65% |
| Zinc, Zn | Approximately 34.22–37.50% |
| Iron, Fe | Maximum 0.20% |
| Lead, Pb | Maximum 0.07% |
| Phosphorus, P | Maximum 0.01% |
| Antimony, Sb | Maximum 0.005% |

| Total impurities | Maximum 0.50% |
Zinc is the balance of the L63 copper-zinc alloy. The final zinc percentage may vary according to the actual copper content and controlled impurity levels.
The low lead limit is one of the main differences between L63 and LS59-1 brass. This composition supports the formability, ductility and fabrication characteristics associated with L63 wrought brass.
LS59-1 Brass Chemical Composition
The following LS59-1 chemical composition values are expressed as percentages by mass.
| Element | LS59-1 Composition |
|---|---|
| Copper, Cu | 57–60% |
| Lead, Pb | 0.8–1.9% |
| Zinc, Zn | Approximately 37.05–42.20% |
| Iron, Fe | Maximum 0.50% |
| Phosphorus, P | Maximum 0.02% |
| Tin, Sn | Maximum 0.30% |
| Antimony, Sb | Maximum 0.01% |
| Bismuth, Bi | Maximum 0.003% |
| Total impurities | Maximum 0.75% |
| Silicon and tin | Si + Sn below 0.50% |
Zinc forms the balance of the LS59-1 copper-zinc-lead alloy. Its lead content improves machining and cutting properties, making the grade suitable for high-volume production of precision brass components.
L63 Brass Mechanical Properties

Key Characteristics
Corrosion Resistance
L63 and LS59-1 provide useful corrosion resistance in normal atmospheric and general industrial environments. L63 is commonly selected when corrosion resistance, forming performance and visual appearance are more important than maximum machining speed.
LS59-1 performs well in many general engineering applications, but service conditions involving aggressive chemicals, ammonia, high chloride concentration or severe stress-corrosion exposure require a separate material assessment.
Machinability
LS59-1 is the preferred option for intensive machining. Its lead content supports chip breaking, reduces cutting resistance and helps produce a smoother machined surface.
L63 can be machined using suitable tools and operating parameters, but it is not normally selected as a direct substitute for free-machining brass when production speed is the primary requirement.
Formability
L63 brass provides better cold-forming performance and is suitable for stamping, drawing, bending and rolling. Annealed L63 brass is especially useful for components requiring substantial deformation.
LS59-1 is more suitable for hot working, forging and machining. Complex cold forming should be evaluated carefully because the leaded structure provides lower cold-forming capability than L63.
Surface Finishing
Both grades can provide an attractive brass finish. Depending on the product and condition, available finishing operations may include:
- Polishing
- Buffing
- Brushing
- Grinding
- Pickling
- Plating
- Protective coating
- Custom surface finishing
Brazing and Soldering
L63 generally offers good brazing and soldering capability. LS59-1 can also be joined using appropriate procedures, but its lead content and intended service conditions must be considered when selecting the joining method.
Standards and Specifications
Product requirements should be selected according to the form being supplied.
| Product Form | Applicable Reference Standards |
|---|---|
| L63 and LS59-1 pipes | GOST 494-90 |

LS59-1 brass for CNC machining can help improve production speed, tool performance and surface quality when compared with brass grades designed primarily for forming.
Manufacturing and Processing
CNC Machining
LS59-1 is generally the stronger choice for CNC turning, milling, drilling and threading because its lead content improves chip control.
L63 can still be machined when the component also requires forming, soldering, appearance or a lower lead content.
Turning and Milling
LS59-1 brass bars and rods are suitable for automated turning and repeat production. Correct cutting tools, speeds, feeds and coolant selection can provide good dimensional accuracy and surface finish.
Forging
Both grades can be hot-worked within their recommended forging ranges. LS59-1 is frequently selected for forged blanks that will undergo secondary machining.
Stamping and Drawing
L63 is the preferred grade for stamping and drawing, particularly in annealed or softer delivery conditions.
LS59-1 should not be selected for demanding cold-forming operations without confirming its suitability through production trials.
Rolling and Wire Drawing
L63 brass can be processed into sheets, strips, coils and wires through suitable rolling and drawing operations.
Welding, Brazing and Soldering
Joining procedures must be chosen according to material thickness, lead content, component design and service environment. Brazing and soldering are commonly considered for fabricated brass assemblies.
Heat Treatment
Neither grade is hardened through conventional quench-and-temper treatment in the same manner as heat-treatable steel. Annealing is primarily used to reduce work hardening, restore ductility and support additional forming or machining.
