Copper Welding Stick For Battery
● Aluminum oxide needle is suitable for spot welding between nickel strip, nickel-permeated steel plate, coated steel strip and other materials in battery production. Used in the production of nickel gas batteries, nickel pot batteries, polymer batteries, lithium batteries and other batteries, spot welding connectors, batteries, extraction parts.
● Product name: Alumina copper spot welding needle, welding needle
● Material: domestic material, Taiwan material, Nissan material, American material
● Needle model: off-core flat head, off-core ball head, same core ball head, straight baseball head, straight rod, other customized
● All the welding needles produced by this manufacturer are made of aluminum oxide copper
● Resistance welding material — nano-alumina dispersion reinforced copper (alumina copper)
● Resistance welding materials expert nano alumina dispersion reinforced copper (alumina copper) Alumina copper — designed for spot welding of galvanized steel plate, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● Aluminum oxide copper material has the advantages of softening resistance and ablation resistance, long service life and high spot welding times.
● Electrode life is more than 5 times that of ordinary chrome-zirconium copper, reducing the shutdown and grinding time of the electrode.
● The battery spot welding machine adopts alumina copper welding needle, which improves the efficiency of automatic welding production line, and provides a terminal solution for welding galvanized steel plate. It is an indispensable electrode material for welding galvanized steel plate, nickel-plated plate, nickel strip, aluminum alloy, stainless steel and brass.
● Softening temperature up to 930℃, which is relatively high in copper alloys, but lower than tungsten copper (1000℃)
● The conductivity of alumina brazing pin is up to 85%IACS, and the heat dissipation performance is between tungsten copper (220 W/m-k) and pure copper (390 W/m-k).
- Avoid sticky electrode phenomenon
- No yellowing of the welding area, beautiful welding joints
- Avoid the occurrence of false welding phenomenon
- Reduce the phenomenon of welding sparks
- Excellent electrical and thermal conductivity and good high temperature performance
- Passed the EU ROHS environmental certification standard
