Product introduction
● 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).
