Aluminum Alloy
This is the most common material for luggage trolley handles, characterized by its light weight, moderate strength, and excellent corrosion resistance. When treated with anodizing, it also exhibits enhanced wear resistance and a superior surface finish, making it suitable for use in most everyday travel suitcases.
Steel
Steel trolley handles offer high strength and exceptional load-bearing capacity, resulting in a more robust and durable structure. Stainless steel variants, in particular, possess excellent rust-resistant properties; however, the material is relatively heavy overall and is typically utilized in medium-to-high-duty or heavy-duty luggage models.
Magnesium Alloy
Magnesium alloy is lighter than aluminum alloy, allowing for further weight reduction while still maintaining a requisite level of structural strength. It is commonly found in mid-to-high-end or lightweight luggage products, though its production cost is relatively higher.
Composite Materials (e.g., Carbon Fiber Reinforced Materials)
These materials boast high strength, extremely low weight, and excellent fatigue resistance. However, due to their high cost, they are typically reserved for high-end or specialized luggage products.
Engineering Plastics
Strictly speaking, these materials are not used for the main trolley shaft itself; however, they are widely utilized in components such as handles, connectors, and locking mechanisms-specifically materials like ABS and PC-to enhance grip comfort and structural stability.
