Bare Aluminium Wire

Bare Aluminum Wire

Bare aluminium wire is developed using aluminum rode to serve matchless quality in various applications such as winding, cabling, and telecommunication. Each bare aluminum wire is fabricated using pure, electrolytic grade, bright annealed bare aluminum with up to 100% conductivity. The conductor is made of multiple strands of finely drawn aluminum wires, thereby offering greater flexibility, which makes these wires ideal for conduit wiring. It is usually used for transformer motors, transformer winding, modern instruments, generators, welding machines,s and so on.

Bare Aluminum Wire Grade:

1100, 1030, 4043, 4048, 7072, 8030, 6201, raw material accepts customization.
