Due to the excellent natural characteristics of aluminum, aluminum profiles have been proven to be good electrical conductors, heat dissipation, and corrosion resistant conductors. Due to their higher structural strength and durability, they are widely used in the market. Many electronic communication devices are made of aluminum, and Dongze's self-developed and produced products have the characteristics of light weight, good heat dissipation performance, high strength, good energy-saving effect, and excellent processing performance. They have been widely used in electronic equipment casings, hard drives CPU heat sink and other fields.
