Alumina Copper Spot Welding Needle For 18650 Lithium Battery
Welding Needle
Product introduction
● It is suitable for spot welding between nickel strip, nickel
permeated steel sheet, coated steel strip and other materials in
battery production. In the production of nickel gas batteries,
nickel pot batteries, polymer batteries, and battery batteries,
spot welding connectors, cells, and extractor sheets.
● Product name: alumina copper spot welding pin, touch welding pin
● Materials: domestic materials, Taiwan materials, Japanese
materials, American materials
● Needle model: partial core flat head, partial core ball head,
same core ball head, straight baseball head, straight bar, other
customization
● The welding pins produced by this manufacturer are all made of
alumina copper
● Resistance welding material - nano alumina dispersion reinforced
copper (alumina copper)
● Alumina copper --- is specially designed for spot welding of
galvanized steel plate, nickel-plated plate, nickel strip, aluminum
alloy, stainless steel, brass and so on
● Alumina copper material is resistant to softening, ablation
resistance, long service life, high number of spot welds, electrode
life is more than 5 times that of ordinary chromium zirconium
copper, reducing the time to stop grinding the electrode.
● Battery spot welding machine adopts aluminum oxide copper welding
pin, which improves the efficiency of the automatic welding
production line, does not bond the electrode when welding the
coated metal, provides a terminal solution for the welding of
galvanized steel plate, and is an indispensable electrode material
for welding galvanized steel plate, nickel plate, nickel strip,
aluminum alloy, stainless steel, brass and so on.
● The softening temperature of alumina copper soldering pin can
reach 930 °C, which is a relatively high alloy in copper, and the
conductivity can reach 85% IACS high strength and good wear
resistance.
● Conductivity up to 85% IACS, heat dissipation performance between
tungsten copper (220 W/m.k) and pure copper (390 W/m-k).
● The softening temperature can reach 930 °C, which is relatively
high in copper alloys, but lower than tungsten copper (1000 °C)
