Zinc alloy die casting is a common method used in luggage hardware due to its corrosion resistance, and good plasticity. It is also easy to weld and braze, and even recyclable, making it more environmentally friendly. This process can produce complex, thin-walled precision parts with a smooth casting surface. Zinc alloy is a versatile material that can be plated, sprayed, painted, polished, or ground to achieve a desired surface treatment. It offers good mechanical properties and wear resistance at room temperature, making it a popular choice for luggage hardware. Compared to iron hardware, zinc alloy is considered mid-range and slightly lighter, which can reduce the weight of the bag. Additionally, zinc alloy hardware comes in a variety of colors and styles, and is crafted with better precision than iron hardware. High-quality zinc alloy hardware has a long-lasting plating layer that does not change color or peel off.
Aluminum alloy is also commonly used in luggage hardware due to its low density and high strength, which provides both durability and lightweight design. This material exhibits good plasticity and can be processed into a variety of hardware fittings. It also boasts excellent corrosion resistance, making it a popular choice for producing parts with high strength requirements, such as luggage handles and levers.
