FAQ
Which material is more durable, zinc alloy or brass?
Brass normally provides stronger corrosion resistance and premium weight, while zinc alloy is strong enough for many bag, garment and fashion hardware programs.
How do cost and lead time compare?
Zinc alloy is usually more cost-efficient for high-volume custom shapes. Lead time depends on tooling, finish approval and testing requirements.
Can zinc alloy look like brass?
Yes. Plating and finishing can create brass-like appearance, but the material weight and corrosion behavior should still be confirmed by application.
Is brass heavier than zinc alloy?
Yes. Brass has higher density and a heavier hand feel, which can be useful for premium hardware but may matter for bags or garments.
Which is better for outdoor use?
Brass is often preferred for higher corrosion exposure. Zinc alloy can still work when plating quality, sealing and testing are specified correctly.
Can both materials use the same finishes?
Many finishes overlap, but plating stack, adhesion and color approval should be checked separately for each base material.
