Straight-Through Alumina Brazing Needle 0.7MM*100MM Spot Welding
Needle
Product introduction
● Product Name: Aluminum Oxide Copper Spot Welding Pin, Butt
Welding Pin
● Material: domestic material, Taiwan material, Nissan material,
American material
● Needle type: eccentric flat head, eccentric ball head, concentric
ball head, straight baseball head, straight rod, other customized
● 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 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 brazing pins are suitable for spot welding between nickel
strips, nickel-impregnated steel strips, coated steel strips 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, and extraction parts.
Product application
Aluminum oxide brazing needle is suitable for spot welding between
materials such as nickel strip, nickel infiltrated steel plate, and
coated steel
strip in battery production. Production of nickel gas batteries,
nickel pot batteries, polymer batteries, lithium batteries, and
other batteries, spot
welding connectors, batteries, and extraction parts.
