Chalco Aluminum advantages of non-clad for automotive brazing sheets
The non-clad of the brazing plate is characterized by a relatively low temperature during the welding process, which has less thermal influence on the metal plate, can weld thinner metal plates, and has good sealing and strength.
Lightweight: brazing sheet non-clad can reduce the weight of automotive structural parts, reduce the fuel consumption and carbon emissions of the car, and also help to improve the handling and driving safety of the car.
Excellent welding performance: there is no need to add additional welding materials during the welding process of the non-clad of the brazing plate, so it can avoid excessive accumulation of alloying elements in the weld zone, reduce deformation and stress concentration in the welding heat-affected zone. This results in excellent welding performance.
Improve production efficiency: the non-clad welding strip of brazing plate can realize continuous production, reduce the intermediate links in the production process, reduce manual operation and production time at the same time, and improve production efficiency.
Good corrosion resistance: there is no iron oxide scale on the surface of the welded joint of the non-composite welding strip of the brazing plate, which can improve the corrosion resistance of the joint and prolong the service life of the car.
Chalco Aluminum application of non-clad for brazing sheets for automobiles
Body: brazing sheet non-composite welding strips can be used for welding body structural parts, such as roofs, doors, trunk lids, hoods, compartments, etc., which can achieve lightweight effects and improve the strength and rigidity of the body, but also helps to reduce vehicle body noise and vibration.
Chassis: brazing plate non-composite welding strip can also be used for welding chassis components, such as front axle, rear axle, steering system, suspension system and other parts, which can reduce weight, improve strength and stiffness, reduce vibration and noise, etc.
Exhaust system: brazing sheet non-composite ribbon can be used in the manufacture of exhaust system, such as exhaust pipe, muffler and other components, which can improve its high temperature resistance and corrosion resistance, and also help to improve the operating efficiency of the car and reduce pollution emissions.
Heat dissipation system: brazing sheet non-composite ribbon can be used in the manufacture of heat dissipation systems, such as radiators, coolers and other components, which can improve the heat dissipation efficiency, improve the operating efficiency of the engine, and prolong the service life of the engine.
Chalco Aluminum manufacturing process of non-clad for brazing sheet for automobiles
Material preparation: choose the appropriate base material and solder, and mix them according to the specified ratio.
Surface treatment: clean the surface of the substrate and perform necessary preheating treatment.
Brazing: apply solder on the preheated substrate, and clamp the two substrates to be welded with a suitable clamp to perform the brazing process. The brazing temperature and time need to be controlled according to the specified parameters, usually under the protection of inert gas to avoid adverse effects such as oxidation.
Cooling treatment: after brazing is completed, the welded joint needs to be cooled to reduce the heat-affected area during the welding process and prevent adverse effects such as welding deformation.
Forming processing: perform necessary forming processing on the welded base material, such as stamping, bending, shearing, etc., in order to form the final auto parts.
Chalco Aluminum packaging of non-clad for automotive brazing sheets
Aluminum is separated by pearl cotton, stacked neatly, and then wrapped with moisture-proof kraft paper, the outermost layer is wrapped with a thicker moisture-proof film, and then steel belt or fiber belt is attached. Packed in export fumigated wooden boxes or wooden pallets. Packaging can also be customized according to customer requirements.
