Brass KS Specifications — 1 sizes
KS D 5201
Copper-zinc alloy (C2801, etc.) with good machinability and corrosion resistance, used for valves, fittings, terminals, and ornaments.
Practical Notes
- C2801 offers good machinability and corrosion resistance but not high strength. For strength, consider phosphor bronze (C5191).
- High-zinc brass (>35% Zn) is susceptible to dezincification. Check zinc ratio for humid environments.

|---|---|---|---|---|---|
| C2600 | Brass | ≥275 | ≥75 | HV60~80 | Spot, , Bolt, |
Key Features
- C2600 (70Cu-30Zn) / C2801 (60Cu-40Zn); higher Zn increases strength but decreases ductility
- Golden appearance; electrical conductivity ~28% of Cu but excellent workability and corrosion resistance
- Good for cold drawing, pressing, and cutting; optimal as plating base metal
Key Applications
Pipe fittings/valves, electrical terminals/connectors, musical instruments (brass), architectural decorative, watch parts
FAQ
Does brass color vary by zinc content?
Yes. 10% zinc (reddish)→20% (golden)→30% (light gold)→40% (bright yellow). C2600 (70/30) provides the most attractive gold color for decorative use.
