Copper has excellent thermal conductivity, making it efficient in transferring heat from the engine to the coolant. It also has good corrosion resistance, ensuring longevity. However, copper radiators can be relatively expensive and susceptible to galvanic corrosion when in contact with dissimilar metals.
Brass, an alloy of copper and zinc, is another popular material for car radiators. While brass has slightly lower thermal conductivity compared to copper, it offers better corrosion resistance. Additionally, brass is more affordable and easier to work with, making it a practical option for radiator construction.
Both copper and brass radiators require proper maintenance, including regular cleaning to prevent clogging and ensure efficient heat transfer. Modern cars often use aluminum radiators, which offer advantages in terms of weight reduction, durability, and resistance to corrosion.
