The composition of the Metal Zipper is also composed of a cloth tape, a microphone, a slider, and a limit code. The teeth of metal zippers are mostly made of copper, white copper, aluminum or zinc alloy. Compared with nylon zippers and Plastic Zippers, Brass Metal Zippers are stronger and cost more. Mostly used on jeans, jackets, backpacks.

When purchasing Metal Fashion Zippers, you must first clarify which types of products are used for metal zippers and the special requirements of the products, such as clothing, bags, shoes, tents, washed denim or leather products with high acidity and other special requirements. Since the raw material of Brass Zipper tape is composed of different types of silk, such as polyester yarns, sutures, and core wires, their components and colorability are different. Therefore, color difference is easy to occur on the same zipper. When you choose to dye evenly without turbidity, the fabrics made of different fabrics are mainly soft to the touch.

The teeth of the metal zipper are also plated and colored, so when buying, you must pay attention to whether the surface is evenly plated, whether there is a phenomenon of color, and whether the zipper is smooth when moving up and down. After the zipper is closed, you must observe whether the left and right teeth are engaged with each other. Asymmetric zipper teeth will definitely affect the use of the zipper.

The upper and lower stops of the metal zipper must be fastened to the teeth or clamped on the teeth, and they must be strong and perfect. There are many shapes of Metal Zipper Sliders, and the finished product can be either small and detailed, or rough and majestic. But no matter what kind of slider, you must feel whether the slider can be opened easily. Will the zipper fail to close or close? The zipper heads currently on the market are equipped with self-locking devices, so after pulling the zipper, please check whether the zipper will slide down after the lower lock head is fixed.

It is important to know that the chemical properties of copper alloys are chemical reactions that occur when they encounter acids, alkalis, oxidants, or reducing agents, and they easily change color. When the chemical residue on the fabric reacts with the fastener elements, the slider or the open end of the metal zipper, the zipper may become discolored. This chemical reaction is more likely to occur under high temperature and high humidity conditions. This situation does not belong to the quality of the zipper.
