Alumina copper spot welding pin
1. Product application range:
Spot welding between nickel strips, nickel-infiltrated steel sheets, coated steel strips 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, batteries, and lead-out pieces.
2. Product features:
1. Avoid sticking electrodes.
2. The welding part is not yellow, and the welding spot is beautiful.
3. Avoid the phenomenon of virtual welding.
4. Reduce the generation of welding sparks.
5. Excellent electrical conductivity and thermal conductivity.
6. Good high temperature performance.
After the solder pin is exposed to the air and used for a period of time, the bottom will become rough and burr, which affects the welding effect and aesthetics. You can use a small file to smooth the bottom to remove the accumulation of oxides, enhance the beauty of the welding surface, and reduce the sticking of pins. happened.

Resistance welding material expert-aluminum oxide copper (nano-alumina dispersion strengthened copper)
Alumina copper ---- designed for spot welding of galvanized steel plate, nickel plate, nickel strip, aluminum alloy, stainless steel, brass, etc.
Main body diameter: 3mm; total length: 80-100mm;
Needle diameter: 1.8mm; Needle length: 10mm.
The softening temperature is as high as 930℃, which is relatively high among copper alloys, but lower than that of tungsten copper (1000℃).
The conductivity is as high as 85% IACS, and the heat dissipation performance is between tungsten copper (220W/MK) and pure copper (390W/mk).
Resistance welding electrode tip, electrode cap, welding wheel, electrode arm, etc.
Contact tips, vacuum switches, electrical connectors, contacts, etc. for cutting and gas shielded welding.
Service areas: electrical engineering, electronics and communications, automobiles, home appliances and container manufacturing, molds, etc.
The performance of dispersion strengthened copper comes from the addition of alumina. The size of alumina particles is 3-12 nanometers, and the particle spacing is about 50-100 nanometers. It has excellent thermal stability, and can maintain the original particle size and particle spacing even at a temperature close to the melting point of copper; the amount of dispersed phase added It only occupies a small volume fraction of the matrix and hardly affects the inherent physical and chemical properties of the matrix metal; therefore, its softening temperature is as high as 930°C, while the electrical and thermal conductivity, hardness and strength can be maintained very well.
