Marine Grade Copper Wire is designed for harsh marine environments, offering superior corrosion resistance. It features tinned copper conductors to prevent oxidation and ensure reliable electrical performance. Ideal for marine electrical systems, it meets stringent safety and durability standards.

Size: 4 AWG to 500 MCM (varies by application)

Grade: ASTM B172, ASTM B3, or equivalent marine-grade standards

Viscosity: N/A (solid material)

Buoyancy: Sinks in water (density ~8.96 g/cm³)

Material: Oxygen-free high-conductivity (OFHC) copper or tinned copper

Insulation: PVC, XLPE, or EPR (oil-, heat-, and moisture-resistant)

Voltage Rating: Typically 600V or higher for marine applications

Temperature Range: -40°C to 90°C (depends on insulation)

Conductivity: ≥ 100% IACS (for pure copper)

Corrosion Resistance: High (tinned copper preferred for saltwater exposure)

Flame Resistance: Meets IEC 60332-1 or equivalent standards

Flexibility: Stranded construction for vibration resistance

Marine Grade Copper Wire and Marine Electrical products typically comply with maritime standards such as ASTM B172, ASTM B174, and IEC 60092 for electrical installations on ships and offshore structures.
