Main performance:

1) hardness & gt; 83HRB,
2) conductivity > 85IACS,
3) Softening temperature 900 C;
4) Dispersion hardening CuA12O3 composites have high strength, high hardness, high conductivity and high softening temperature.  
5) In the United States, Japan and other countries have been widely used in large microwave tube structures and conductive materials, switching switches, silver contacts and spot welding electrodes, etc.. The material is produced through the Cu-Al alloy internal oxidation-isostatic embossed embryo-sintering-thermal extrusion-pulling-processing molding process. It has good thermal stability, good plasticity and processing performance. &; nbsp;
6. The supergroup corrosion resistance of galvanized steel sheet with resistance welding electrodes makes it widely used in more and more fields, but it also brings new problems to resistance welding technology. How to avoid yellowing of welding joints, virtual welding and zinc sticking of electrodes during welding process, which lead to the decline of product quality and low work efficiency, becomes more and more urgent. Dispersed Al-Cu alloy is undoubtedly the most important one. Ideal materials have excellent resistance to welding and arc burning for welded coated steel plate and nickel plate, which can improve the service life of electrodes, reduce the frequency of electrode dressing, and minimize the possibility of welding interruption and virtual welding. They are especially suitable for welding pure nickel strips and nickel-permeated steel sheets in the production of mobile phone batteries.  
7). With the development and progress of the electronic industry, lead frame materials and electronic packaging materials, the lead material requirements of electronic components such as large-scale integrated circuits are getting higher and higher. The high temperature and rigidity of dispersion reinforced copper alloys will gradually replace traditional ferronickel alloys. material. &; nbsp;

Application: Suitable for spot welding between nickel strip, Nickelized steel sheet and coated steel strip in battery production. In the production of Ni-MH batteries, Ni-Cd batteries, polymer batteries, lithium batteries and other batteries, spot welding connectors, cores and lead-out sheets are used.  

Main welding advantages: &; nbsp;

1. Avoid electrode sticking.  
2. The welding site is not yellow, and the welding point is beautiful. &; nbsp;
3. Avoid the phenomenon of virtual welding.  
4. Put an end to the phenomenon of welding spark is generated.
5. Excellent electrical conductivity and thermal conductivity. The
6. Good high temperature performance.  
7. As to meet the requirements of SGS environmental protection standard requirements and MSDS.
