EV Battery Hard Copper Busbar
EV Battery Hard Copper Busbar
Key Features For Copper Busbar:
High Purity Copper Material
Made of T2/TU2/C11000 copper (≥99.99% Cu), conductivity up to ≥97% IACS, low resistivity 0.01724 Ω·mm²/m, minimizes energy loss and heat generation.
Superior Electrical & Thermal Performance
Excellent heat dissipation, effectively reduces temperature rise under high current; ensures long-term stability for EV battery packs and energy storage systems.
Custom CNC Machining
Precision cutting, bending, drilling, stamping; custom size, shape, hole position according to your battery pack layout.
Multiple Surface Treatment
Bare copper / tin plating (3–12μm) / nickel plating / silver plating; anti-oxidation, anti-corrosion, improves solderability.
