There are two main types of automotive radiators: aluminum and copper, the former for general passenger cars and the latter for large commercial vehicles Automotive radiator materials and manufacturing technology are developing rapidly. Aluminum radiator With its obvious advantages in lightweight materials, in the field of cars and light vehicles gradually replace copper radiator at the same time, copper radiator manufacturing technology and technology has been a great development, copper hard brazing radiator in passenger cars, construction machinery, heavy trucks and other engine radiators advantage is obvious. Foreign cars supporting the radiator is mostly aluminum radiator, mainly from the point of view of environmental protection (especially in Europe and the European countries). Aluminium Radiators account for an average of 64% of the new cars in Europe. From the development prospect of automobile radiator production in China, the aluminum radiator produced by hard brazing gradually increases. Hard brazing Copper radiators are also used in buses, trucks and other engineering equipment.
