Straight-Through Alumina Brazing Needle 0.7MM*100MM Spot Welding Needle
● 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.
