Alumina Copper Spot Welding Needle For 18650 Lithium Battery Welding Needle

● 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)
