18650 Lithium Battery Welding Needle Imported High Quality Welding Needle
● Aluminium oxide brazing pins are suitable for spot welding
between materials such as nickel strips, nickel-permeable steel
plates, coated steel strips, etc. in battery production. Used in
the production of nickel gas batteries, nickel pot batteries,
polymer batteries, lithium batteries and other batteries, spot
welded connectors, cores, extraction parts.
● Product Name: Aluminium Oxide Copper Spot Welding Needles, Touch
Welding Needles
● Product Material: Domestic material, Taiwan material, Japanese
material, American material.
● Needle type: Off-centre flat head, Off-centre ball head,
Same-centre ball head, Straight baseball head, Straight stick,
Other customized
● All of our welding needles are made of aluminium oxide copper.
● Resistance Welding Material--Nano Aluminium Oxide Diffusion
Reinforced Copper (Aluminium Copper Oxide)
● The resistance welding material expert nano alumina diffusion
reinforced copper referred to as (alumina copper) alumina copper -
designed for spot welding of galvanised steel, nickel-plated
plates, nickel strips, aluminium alloys, stainless steel, brass and
so on.
● The material of alumina copper has the advantages of softening
resistance, abrasion resistance, long service life and high number
of spot welding.
● The electrode life is more than 5 times that of ordinary chrome
zirconium copper, which reduces the downtime and grinding time of
the electrode.
● Battery spot welder adopts the welding needle made of alumina
copper, which improves the efficiency of the automatic welding
production line, and does not bond the electrode when welding
plated metal, which provides a terminal solution for welding
galvanised steel, and is an indispensable electrode material for
welding galvanised steel, nickel-plated plates, nickel strips,
aluminium alloys, stainless steels, brasses, and so on.
● The high softening temperature of 930℃ is relatively high among
copper alloys, but lower than tungsten copper (1000℃)
●Aluminium oxide copper welding pin conductivity up to 85% IACS,
heat dissipation performance between tungsten copper (220 W/m-k)
and pure copper (390 W/m-k).
