The short answer: zinc alloy is the go-to for custom-shaped, detailed and enamel-filled keychains because it casts fine detail and takes plating beautifully, while stainless steel is prized for plain, ultra-durable hardware. Most custom logo and novelty keychains are zinc alloy.
Zinc alloy keychains
- Casts intricate 2D/3D shapes and logos with sharp detail
- Takes soft enamel color and plating (gold, silver, gunmetal, rainbow, black nickel)
- Cost-effective for custom and promotional runs
Stainless steel keychains
- Highly durable and corrosion-resistant
- Best for plain or simple engraved designs and hardware
- Harder to cast into detailed custom shapes
