Introduction:
Alumina copper electrode material, suitable for spot welding between precision metal spot welding and spot welding of nickel strip, nickel plated steel sheet, plated steel strip and other materials in battery production.
In the production of nickel-metal hydride batteries, nickel-cadmium batteries, polymer batteries, lithium batteries and other batteries, spot welding connecting pieces and battery lead pieces.

Features:
1. The phenomenon of sticking electrodes can be avoided
2. The welding part is not yellow, and the welding point is beautiful
3. Avoid the phenomenon of virtual welding
4. Reduce the phenomenon of sparks during welding
5. Very good electrical and thermal conductivity
6. Good high temperature performance
Introduction of Alumina Copper:
The softening temperature is as high as 930 degrees Celsius, which is relatively high among copper alloys, and the conductivity is as high as 85% IACS, with high strength, good fatigue performance and good wear resistance.
Resistance welding material expert-spot welding design of nano-galvanized steel, nickel-plated steel, nickel strip, aluminum alloy, stainless steel, brass, etc.

Advantages of this product:
Softening resistance, wear resistance, ablation resistance, long service life, high spot welding times, electrode life is more than 5 times that of ordinary chromium zirconium copper, reducing the time of downtime for grinding electrodes, and improving the efficiency of automatic welding production lines. Welding of coated metals When the electrode is not bonded, the terminal solution for the welding of galvanized steel sheet is to weld galvanized steel sheet, nickel-plated sheet, nickel strip, aluminum alloy, stainless steel, brass and other indispensable electrode materials.

Features:
The softening temperature is as high as 930%, which is relatively high among copper alloys, but lower than tungsten copper (1000°C). The conductivity is as high as 85% IACS. The heat dissipation performance is between tungsten copper (220 W/mk) and pure copper (390 W/mk). ), high strength, good fatigue performance and wear resistance. Personal opinion of the shopkeeper: With the same parameters of the spot welder and the same nickel sheet, the tip of the spot welding needle can be a little firmer. If the needle is awkward, the spot welding ability will drop a little. Some weak spot welders can sharpen the needle a little bit. ! Because the spot welding machine is "spot welding" as the name implies, a spot generates a lot of heat, and the spot is larger, and the heat is also dispersed. From the perspective of current, the same current has a small cross-sectional area and a high current density, so the heat is more concentrated. The pointed head of the needle. Therefore, the welding needles are often sharpened. Of course, the spot welding area and spot welding fastness must be considered. The needles should not be made as sharp as the sewing needles.
