C15760 Welding Needle spot welder Aluminum oxide copper welding needle for battery

● It is suitable for spot welding between materials such as nickel strips, nickel-permeable steel sheets, and coated steel strips in the production of batteries. Spot welding of connecting pieces, cells and lead-in pieces in the production of batteries such as nickel gas batteries, nickel pot batteries, polymer batteries and rational batteries.

​●Product Name: Aluminum Oxide Copper Spot Welding Needles, Touch Welding Needles

​●Material: Domestic material, Taiwan material, Japanese material, American material.

​●Pin type: Off-center flat head, Off-center ball head, Same-center ball head, Straight baseball head, Straight bar, Other customization
All the welding needles produced by our factory are made of aluminum oxide copper.

● Resistance welding material--Nanometer alumina diffusion strengthened copper (aluminum oxide copper)

● Aluminum copper oxide----specifically designed for spot welding of galvanized steel, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, and so on.

●  Alumina copper material is resistant to softening and ablation, long service life, high number of spot welding, electrode life is more than 5 times that of ordinary chrome zirconium copper, reducing downtime for electrode repair and grinding.

● Battery spot welder adopts alumina copper material welding needle, which improves the efficiency of automatic welding production line, and does not bond the electrode when welding coated metal, which provides a terminal solution for welding galvanized steel, and is an indispensable electrode material for welding galvanized steel, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass and so on.

● Alumina copper welding needles softening temperature up to 930 ℃, is a relatively high alloy of copper, conductivity up to 85% IACS high strength, 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).

● Softening temperature up to 930 ℃, which is higher than that of copper alloys, but lower than tungsten copper (1000 ℃)
