Brass Sheet is a flat-rolled product made from brass, a copper–zinc alloy known for its gold-like appearance, excellent corrosion resistance, and superior formability.
With a smooth surface finish, good machinability, and natural antimicrobial properties, brass sheet is widely used in decorative, industrial, electrical, and architectural applications.
Typical Chemical Composition
| Brass Grade | Cu % | Zn % | Other Elements | Sheet Characteristics |
|---|---|---|---|---|
| Cartridge Brass (C26000) | ~70 | ~30 | — | Excellent deep drawing |
| Yellow Brass (C27000) | 63 – 68 | Balance | — | Balanced strength & formability |
| Commercial Brass (C28000) | ~60 | ~40 | — | Higher strength |
| Naval Brass (C46400) | ~60 | ~39 | Sn ~1% | Marine corrosion resistance |
| Leaded Brass | 60 – 63 | 33 – 37 | Pb 1 – 3% | Machinable sheets |
| Lead-Free Brass | 60 – 75 | Balance | Bi, Si | Drinking-water safe |
Key Insight: Sheet brass grades are typically low-lead or lead-free to preserve ductility and surface quality.

Annealed sheets provide maximum formability, while cold-rolled (hard) sheets deliver higher strength.
Strengthening & Metallurgical Behavior
✔ Alpha-phase brass provides ductility and corrosion resistance
✔ Alpha + beta structure increases strength with reduced formability
✔ Zinc provides solid-solution strengthening
✔ Cold rolling is the primary strengthening method
✔ Not precipitation hardenable
