Aluminum zippers have several advantages:

1. Lightweight: Aluminum zippers are lighter compared to other materials like brass or plastic zippers. This makes them suitable for applications where weight is a concern, such as in lightweight clothing or outdoor gear.

2. Affordable: Aluminum zippers are relatively cheaper than zippers made from other materials like brass or steel. This makes them a popular choice for budget-conscious consumers or for mass-produced garments.

3. Durability: Despite being lightweight, aluminum zippers are still quite durable. They have good resistance to corrosion, making them suitable for use in outdoor or marine applications where exposure to moisture or saltwater is common. Aluminum zippers also have a high strength-to-weight ratio, which ensures they can withstand frequent use and provide reliable performance over time.

These advantages make aluminum zippers a popular choice in various industries, including fashion, outdoor gear, and luggage manufacturing.
