C2680 Brass Sheet – High Corrosion Resistance & Excellent Machinability for Electronics, Automotive, Mechanical Applications
C2680 brass sheet is a copper-zinc alloy material widely used in electronics, automotive systems, machinery manufacturing, and construction industries. It offers a strong balance of corrosion resistance, machinability, and electrical conductivity, making it suitable for precision engineering applications.
This grade is typically produced with customized thickness and width, and supplied in sheet or plate form according to ASTM standards.
Many industrial applications require a material that combines:
- Better strength than pure copper
- Improved corrosion resistance
- Stable electrical performance
- Easier machining and forming ability
Pure copper is too soft, while many metals lack conductivity or corrosion resistance. C2680 brass solves this balance problem.
C2680 brass sheet delivers:
- Excellent machinability for precision parts
- Good corrosion resistance in industrial environments
- Stable electrical conductivity
- High ductility for deep drawing and forming
- Long service life in mechanical and electrical systems

Copper and brass sheet plates are widely used in:
- Electrical components (busbars, connectors, terminals)
- Automotive parts (radiators, heat exchangers)
- Construction and architectural decoration
- Industrial machinery components
- Marine engineering parts
- Precision instruments (springs, gauges, sensors)
- Fasteners and hardware (nuts, rivets, washers)
C2680 brass is a copper-zinc alloy:
- Copper provides conductivity and corrosion resistance
- Zinc increases strength and hardness
- The alloy structure improves machinability and plastic deformation
This balance makes it suitable for both electrical and mechanical applications.
When selecting the right grade:
- Choose C11000 / C10200 for high conductivity (electrical use)
- Choose brass C21000 - C27400 for mechanical strength + corrosion resistance
- Choose C17200 / C17500 for high strength spring or load-bearing parts
- Choose thickness based on load: thin sheets for electronics, thick plates for structural use
- Consider surface finish for decorative or precision requirements
When selecting this material, consider:
- Thickness: thin sheets for electronics, thicker plates for machinery
- Surface finish: coated vs raw metal depending on environment
- Mechanical condition: soft / half-hard / hard temper
- Conductivity requirement: higher for electrical parts
- Processing method: stamping, bending, or CNC machining
