C2680 Brass Sheet – High Corrosion Resistance & Excellent Machinability for Electronics, Automotive, Mechanical Applications

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

• Tensile strength: 350–450 MPa
• Yield strength: 180–250 MPa
• Elongation: ≥30% (high ductility)
• Hardness: ~60–80 HB (adjustable via processing)

• Electrical conductivity: 20–30% IACS
• Good thermal stability
• Moderate-to-high corrosion resistance
• Excellent formability and stamping performance

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
