​● 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).
