How to choose a metal zipper
2. Chain teeth material: The chain teeth of metal zippers are usually made of materials such as copper alloy, aluminum alloy, etc., which are wear-resistant, pressure resistant, and corrosion-resistant. Compared to ordinary plastic zippers, metal chain teeth are more sturdy and durable
3. Pulling characteristics: The texture and smoothness of metal pulls are very important. Metal pulls usually have a metallic luster and a smooth feel. Different models of zippers have different uses, for example, the 2nd zipper is suitable for skirts and pillows, while the 5th zipper is standard for luggage and outdoor products
4. Color and weight: Metal zippers come in a variety of colors, commonly silver and gold. Due to the material, metal zippers are usually heavier than nylon or resin zippers. By observing the color and weight, the quality of the zipper can be preliminarily judged
When choosing a metal zipper, the following aspects can be considered:
1. Zipper grades and specifications: Metal zippers are usually classified into grades A, B, C, etc. The higher the grade, the better the quality. Common specifications include size 3, 5, 8, 10, etc. The larger the size, the larger the specification. Each specification of zipper has a standard weight, which is also the key to measuring quality2.
