Product introduction
● Product Name: Aluminum Oxide Copper Spot Soldering Pin, Touch Soldering Pin
● Material: Domestic material, Taiwan material, Japanese material, American material.
● Needle type: Off-center flat head, Off-center ball head, Same-center ball head, Straight baseball head, Straight bar, Other customized
All of our soldering pins are made of aluminum oxide copper.
● Resistance welding material–Nanometer alumina diffusion strengthened copper (aluminum oxide copper)
● Resistance welding material expert nano alumina diffusion reinforced copper referred to as (alumina copper) alumina copper – designed for spot welding of galvanized steel, nickel-plated plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
● Alumina copper material has the advantages of anti-softening, ablation resistance, long service life, and high number of spot welds.
● Electrode life is more than 5 times that of ordinary chrome zirconium copper, reducing electrode downtime and grinding time.
● 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.
● The softening temperature is up to 930°C, which is relatively high among copper alloys, but lower than tungsten copper (1000°C)
● Aluminum oxide copper brazing pins have an electrical conductivity of up to 85% IACS, with heat dissipation performance 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-permeable steel plates, coated steel strips and other materials in battery production. It is used in the production of batteries such as nickel gas batteries, nickel pot batteries, polymer batteries, lithium batteries, etc., spot welding of connectors, cores and extractors.
