1. products: spot welding work between nickel strip, nickel permeable steel sheet, coated steel strip and other materials in

battery production. In the production of nickel-hydrogen batteries, nickel-cadmium batteries, polymer batteries, lithium batteries and other batteries, spot welding connecting pieces, batteries, lead-out pieces.

2. product features:

1. Avoid sticking electrode phenomenon.

2. The welding parts shall not be yellow and the welding spots shall be beautiful.

3. Avoid virtual welding.

4. Reduce the generation of welding sparks.

5. Excellent electrical conductivity and thermal conductivity.

6. Good high temperature performance.

Tips: After the

welding needle is exposed to the air for a period of time, the bottom will become rough and burr, which will affect the welding effect and aesthetics. A small file can be used to smooth the bottom, remove the accumulation of oxidation, enhance the beauty of the welding surface, and reduce the occurrence of needle sticking.

is as high as 85% IACS, and the heat dissipation performance is between tungsten copper (220 W/M.K) and pure copper (390W/m-k).

Products:

resistance welding electrode head, electrode cap, electric welding wheel, electrode arm, etc. Conductive nozzles, vacuum switches, electrical connectors, contacts, etc. for

cutting and gas shielded welding.

service areas of electrical, electronic and communications, automotive, home appliances and container manufacturing, molds, etc.

The properties of dispersion strengthened copper are derived from the addition of alumina. The size of alumina particles is 3~12 nm, and the particle spacing is about 50~100 nm. Its thermal stability is excellent, and it can still maintain the original particle size and particle spacing even at a temperature close to the melting point of copper. The addition amount of dispersive phase only accounts for 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 ℃, at the same time, the electrical and thermal conductivity, as well as the hardness and strength can be maintained very well.
