From a manufacturing perspective, the materials used in creating the 3600A brake drum also affect its weight. Most brake drums are made from cast iron or aluminum alloys. Cast iron drums are generally heavier and provide excellent durability, making them well-suited for heavy-duty applications. Conversely, aluminum drums offer advantages in terms of weight reduction, which can increase fuel efficiency and improve overall vehicle performance. The choice of material, therefore, represents a critical factor in balancing weight, durability, and performance.
