Double metal truck brake drums are 20 to 35% lighter than traditional gray iron casting brake drums, resulting in significantly improved braking effects and a longer service life.

These brake drums are manufactured from high strength steel shell and a high-performance cast iron friction ring. Both materials are processed using special technology, giving them high-strength, good thermal conductivity, and their light weight. The shell also has large heat dissipating area and excellent performance, helping to effectively eliminate cracking phenomenon caused by thick walls, poor heat dissipation, and high temperature differences. When using this type of brake drum, the truck reduces its chassis weight along with fuel consumption. This also enhances the safety of the truck.

Comparison between double metal truck brake drums and traditional brake drums
Double Metal Truck Brake Drum

1. Structure
The double metal truck brake drum shell is made of high strength steel and its interior adopts abrasion-resistant cast alloy iron. The double metal layers are combined using a special metallurgy composite technology. Therefore, the overall performance is improved in many ways.

2. Thickness
The wall thickness of the double metal truck brake drum is 8-10mm thinner than traditional brake drums that operate with the same specifications. It features the advantages of a compact structure, light weight, and fast heat dissipation.

  • Traditional brake drumTraditional brake drum

3. Weight
Double metal truck brake drums are over 25% lighter than traditional brake drums with the same specification, thus making them considerably more fuel-efficient!

  • Traditional brake drumTraditional brake drum

4. Safety Performance
The inner wall of the double metal truck brake drum will not crack until it experiences a 22mm compressive deformation, something that would require an extreme amount of force. Additionally, the steel shell will never crack. However, traditional brake drums will break into pieces following a compressive deformation of just 5mm.

5. Manufacturing Technology
The double metal truck brake drum shell adopts a special machine for plastic forming. By incorporating loading and unloading, an assembly line, conveying, distributing, and positioning devices, unmanned, and automatic production is achieved, minimizing operating costs.
