Copper Alumina Welding Needle Lithium Battery Assembly Welding Accessories
● The welding pins produced by this manufacturer are all made of aluminum oxide copper
● Resistance welding material - nano-alumina dispersion strengthened copper (alumina copper)
● Expert in resistance welding materials Nano-alumina dispersion strengthened copper for short (alumina-copper) alumina-copper—specially designed for spot welding of galvanized steel plate, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● Alumina copper material has the advantages of anti-softening and ablation resistance, long service life and high frequency of spot welding.
● The service life of the electrode is more than 5 times that of ordinary chrome-zirconium copper, which reduces the downtime and grinding time of the electrode.
● The battery spot welder uses aluminum oxide copper welding pins, which improves the efficiency of the automatic welding production line, and does not bond electrodes when welding plated metals. It provides a terminal solution for the welding of galvanized steel sheets. It is suitable for welding galvanized steel sheets, Indispensable electrode materials such as nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● The softening temperature is as high as 930°C, which is relatively high among copper alloys, but lower than tungsten copper (1000°C)
●The conductivity of aluminum oxide brazing pin is as high as 85%IACS, and the heat dissipation performance is between tungsten copper (220 W/m-k) and pure copper (390 W/m-k).
●Alumina copper welding pins are suitable for spot welding between nickel strips, nickel-impregnated steel strips, and coated steel strips 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, and extraction parts.
