Aluminum copper radiator clean

Copper Aluminum Radiators are generally sourced from high-performance vehicles.

The main materials of copper aluminum radiators are aluminum and copper, with a significant difference in value, exceeding three times. Therefore, in addition to controlling non-metallic impurities and iron impurities, it is also necessary to clarify the ratio of aluminum to copper. Generally, the weight ratio of aluminum to copper in conventional copper aluminum radiators is around 3:2, i.e., 60% aluminum and 40% copper.

1. Sorting: Sort different materials of automotive radiators by material, such as brass, copper aluminum, and pure aluminum radiators, to maximize their value. Copper aluminum radiators have copper parts (usually pipes) that are reddish-brown, while aluminum parts (usually fins) are silver-white.

2. Disassembly: Separate metal and non-metal parts (such as plastic, rubber hoses, and sealant strips) from the water tank structure, and separate colored metals and iron. They can greatly affect the price of the main material. The water tank head often has more iron impurities and requires strict separation.
3. Crushing + machine sorting or manual disassembly: Depending on the equipment conditions and labor costs. Some factories with crushing and complete sorting equipment will crush the water tank after removing the external attachments and then separate the crushed copper pipes and aluminum through flotation and other equipment. If there is no crushing and sorting equipment, manual disassembly can only be performed. The rough disassembly method is to remove the heat pipes and then peel off the heat fins one by one.
4. Smelting or sales: At this point, the crushed aluminum and copper pipes can be sold as colored metal scrap or directly used for smelting and production.

1. With/without impurities
   Generally, clean copper aluminum water tanks do not contain metallic impurities, such as iron water tank heads and iron mounting brackets; however, they may contain non-metallic impurities, such as water tank sealant strips. Whether or not to include impurities is crucial information in transaction communication.
2. Clean/dirty
   Copper aluminum water tanks often have a large amount of mud, which is a normal and common situation. Dirty water tanks usually have 2%-3% mud. However, some automotive radiators are sold in a clean state after cleaning. In transactions, it should be specifically noted and agreed upon.
3. Material clarification
   Different materials of water tanks have a large price difference. In transactions, it should be strictly ensured that low-value pure aluminum radiators are not mixed with high-value copper aluminum water tanks. Different materials of radiators have distinct external differences, and mixing in pure aluminum radiators is often a malicious act.
