1. Product description
      Cladded aluminum material is suitable for a variety of brazing processes,such as Nocolok brazing and vacuum brazing. It's widely used in engine cooling and air conditioner systems in automotive industry,such as radiator,condenser,evaporator,intercooler,oil cooler and heater. In home electrics industries,such as HVAC heat exchanger,water heater,PTC heating unit; In the industrial field,such as power plant cooling systems,construction machinery and air separation equipment. Our cladded aluminum material highly recommended in the market for its stable mechanical properties,stable cladded percentage and excellent corrosion resistance.
       We have developed lots of new alloys for heat exchangers to meet the different technical requirements of customers.According to our continuous internal research and customer feedbacks,we have developed our series alloys which are more suitable for customers than standard alloys.We have alloys with various properties for different applications such as long life alloy tubes,collapse resistant alloy for fins,high strength aging alloys for plates,etc.
