Metal zippers are essential components in many sewing projects that require strength, longevity, and a touch of classic style. Whether you’re crafting denim jeans, jackets, handbags, or workwear, using the right type of metal zipper ensures functionality and enhances the overall appearance of your product.
In this guide, we’ll break down everything you need to know about metal zippers for sewing, including types, materials, key features, and tips on choosing the right one.
🔍 What Is a Metal Zipper?
A metal zipper is a fastening device with interlocking metal teeth mounted on a fabric tape. Unlike nylon or plastic zippers, metal zippers are sturdier, more wear-resistant, and often used in garments or products that require high durability.
✅ Common Metals Used in Zippers:
- Brass – Rust-resistant, antique gold tone, popular for jeans and leather goods
- Nickel – Silver-toned finish, widely used in outerwear and accessories
- Aluminum – Lightweight, matte silver color, easy to open and close
- Black Oxidized / Antique Finishes – Vintage look, favored for fashion brands
🧠 Tip: Brass is often preferred for its balance between strength, appearance, and cost.

🔧 Sewing Tips for Metal Zippers
- Use a zipper foot to stitch close to the teeth
- Choose a strong needle (e.g., size 90/14 or 100/16) to prevent breakage
- Avoid sewing over the metal teeth – it can damage your needle or machine
- Baste first, then topstitch for clean results
