Die-cast aluminum heating radiators are divided into two categories according to their adaptability to water quality and the material of the water channel: integral (all aluminum) and composite (lined with steel pipe). The die-cast aluminum alloy single-piece radiator processed by die-casting technology is integral; the single-piece radiator made of die-cast aluminum and made of steel pipe or stainless steel pipe for the water channel is composite. In layman's terms, the die-cast aluminum composite radiator is a steel radiator with an aluminum alloy coat and increased heat conduction area.
Die-cast aluminum heating radiators originated in Europe and have a history of several decades. The production is mainly concentrated in Italy. This product is a product with high technical content, complex process, fine processing, high efficiency and energy saving, simple and beautiful, and safe to use. It is widely used in Eastern Europe and Western Europe. At the beginning of this century and the end of the last century, die-cast aluminum heating radiators produced in Italy began to be marketed in the Chinese market through dealers. However, due to the limitations of its channels, consumers' awareness and high prices are only used in a small range. In 2004, some Italian manufacturers began to look for partners in China. Some dealers in Eastern and Western Europe came to China with samples, looking for manufacturers with rich experience in die-casting and producing automobile and motorcycle die-casting parts. Some private enterprises in Jiangsu and Zhejiang with rich experience in die-casting technology keenly seized the business opportunity. Since then, the manufacturing of die-cast aluminum heating radiators has gradually formed a scale in China. In the past few years, the production capacity of this product in China has reached a production scale of more than 80 million pieces, and the products are mainly exported to Russia and some countries in Eastern and Western Europe.
