Brass Magnetic Snap — Specification, Uses and Sourcing Notes
Brass Magnetic Snap: Specification, Uses and Sourcing Notes
Brass Magnetic Snap is the version buyers specify when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
Brass gives magnetic snap its weight-to-strength ratio. In practice that means the trim behaves differently in cutting, in finishing and in wear: tighter tolerance is needed on the finished dimension. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.
Typical specification
| Item | Magnetic Snap |
|---|---|
| Base material | Brass |
| Standard size | 50 mm Width |
| Common finishes | Glossy Enamel Coating, Antique Copper Finish, Soft-Touch Rubber Coating |

Properties that matter in buying
- Dimensional stability — 2% allowance is built into the spec before cutting.
- Colour fastness — tested to JIS L Standards on the actual base material, not on a substitute.
- Mechanical performance — abrasion resistance after 30 cycles or washes.
- Compliance — JIS L Standards documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.
Common uses
- Evening Wear
- Bags
- Workwear
- Blouses
- Outdoor Tents
- Shirts
How to specify it
- Name the base material in the tech pack, not just the item.
- Fix the size and tolerance in writing before sampling starts.
- Approve a counter sample made from the actual bulk base material.
- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
