Welding Needle Alumina copper spot welding needle double eccentric needle
Product introduction
● It is suitable for spot welding between nickel strip, nickel-infiltrated steel sheet, coated steel strip and other materials in battery production.
Spot welding connecting piece, core and lead sheet in the production of nickel gas battery, nickel pot battery, polymer battery, management battery and so on.
● Product name: alumina copper spot welding needle, contact welding needle.
● Materials: domestic materials, Taiwan materials, Japanese materials, American materials.
● Needle type: eccentric flat head, eccentric ball head, concentric ball head, straight ball head, straight bar, other customized.
● The welding needles produced by our factory are all made of alumina copper.
● Resistance welding material-nanometer alumina dispersion strengthened copper (alumina copper).
● Alumina copper-specially designed for spot welding of galvanized steel sheet, nickel plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● Alumina copper material has the advantages of softening and ablation resistance, long service life, high spot welding times, and the electrode life is more than 5 times that of ordinary chromium-zirconium copper, which reduces the time of shutting down and grinding the electrode.
● The battery spot welding machine adopts a welding needle made of alumina copper, which improves the efficiency of the automatic welding production line and does not bond the electrode when welding the coated metal, which provides a terminal solution for the welding of galvanized steel plate. It is an indispensable electrode material for welding galvanized steel plate, nickel strip, aluminum alloy, stainless steel, brass and so on.
● Alumina copper welding needle softening temperature up to 930C, is a relatively high alloy in copper, electrical conductivity up to 85% IACS high strength, good wear resistance.
● The electrical conductivity can reach 85% IACS, and the heat dissipation performance is between tungsten copper (220 W/m.k) and pure copper (390 W/m-k).
● The softening temperature is 930C, which is higher than that of copper alloy, but lower than that of tungsten copper (1000 ℃).
