Product Description
The 3xxx Series Ductile Aluminum Wire for Electrical Use emerges as a versatile conductor solution engineered to optimize performance in high-efficiency electrical systems. Composed of aluminum-manganese alloys (3003 and 3004), these wires combine excellent electrical conductivity with superior formability, addressing the needs of power transmission, automotive wiring, and renewable energy applications. Their manganese content enhances strength without sacrificing flexibility, making them a cost-effective alternative to copper in low-to-medium voltage systems.
Parameter | Value |
Alloy Type | 3003, 3004 |
Diameter | 0.5–50mm |
Tensile Strength | 110–200MPa (H14 temper) |
Electrical Conductivity | ≥50% IACS |
Elongation | 15–25% (H14 temper) |
High Electrical Efficiency: 3003-H14 wires achieve low resistivity (≤3.44μΩ·cm), minimizing power loss by up to 15% in long-distance transmission lines compared to lower-grade aluminum alloys.
Exceptional Ductility: Withstands 100+ bending cycles (180° radius = wire diameter) without cracking, enabling complex routing in automotive wiring harnesses and tight electrical enclosures.
Corrosion Protection: The aluminum-manganese alloy forms a dense oxide layer that resists humidity, industrial fumes, and UV exposure, ensuring a service life of 20+ years in outdoor applications.
Cost-Effective: Offers 20–30% material cost savings over copper conductors while maintaining comparable current-carrying capacity in 600V and lower systems, reducing overall project expenses.
Power Grids: Used in overhead distribution lines and secondary service drops, where their lightweight design (2.7g/cm³) reduces pole load and simplifies installation in wind-prone areas.
Automotive Electronics: Integral to engine control units (ECUs), battery management systems, and sensor wiring, leveraging flexibility to withstand vibration and temperature fluctuations (-40°C to 125°C).
Solar & Wind Energy: Conductors in solar panel combiner boxes and wind turbine generators, where their high-temperature stability prevents performance degradation in outdoor installations.
Appliance Wiring: Employed in refrigerators, air conditioners, and power tools, balancing conductivity with ease of termination in compact spaces.
Q: Is 3003 aluminum wire suitable for high-voltage applications?
A: 3003 excels in low-to-medium voltages (≤600V). For high-voltage (≥1kV) use, 1350 aluminum (99.5% purity) offers superior conductivity (≥61% IACS) but with reduced strength.
Q: Can it be used in saltwater environments?
A: For marine or coastal electrical systems, 5052 aluminum wire (with 2.5% magnesium) provides enhanced corrosion resistance, though it has slightly lower conductivity than 3003.
