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 ℃).
