Zinc AlloyStart with the everyday clip

A key-carrying clip gives zinc alloy a clear role in EDC. Look at the clip itself, then separate its material from its colour, moving parts and the objects hanging below it.

Orbitkey identifies the Clip v2 Add-on as zinc alloy and offers All Black and Silver versions. Those are colour options, not two different base-material declarations.

The All Black standalone clip. The maker lists zinc alloy without specifying a grade or the composition of the black finish.

The material belongs to the clip

A dark Orbitkey clip attached to a webbing loop, with keys hanging from a separate key ring below — The maker’s carrying example. Clip, ring, keys and webbing are separate objects; the clip’s material specification does not describe the whole set.

The Clip v2 Add-on is a separate attachment for key carrying, belt loops and bags. Orbitkey lists dimensions of 57 × 35 × 5 mm and a box containing the clip and a quick-start guide.

The photograph shows the closed gate and its side connection. It helps explain attachment, but does not establish gate force, fatigue life or a load rating.

One material declaration, two looks

All Black and Silver sit under the same zinc-alloy specification. The silver-coloured photograph shows bright reflections; the black version appears darker. Neither colour identifies a coating or finishing process.

More specific finish-care advice would require that missing information. The appearance alone is not a basis for recommending a metal polish or assigning a particular coating to the black surface.

The silver-coloured Orbitkey Clip v2 Add-on, shown with its gate closed — The Silver version. Silver is the colour option here, not evidence that the clip is made from silver.

An alloy family, not a grade

The International Zinc Association distinguishes ZAMAK and ZA casting-alloy families: the former contain approximately 4% aluminium, while the latter contain more. Zinc alloy therefore does not identify one fixed grade.

The association also describes manufacturing and finishing options. This is material background, not evidence that this Orbitkey item uses a particular alloy, casting process or coating.

Keep the intended use in view

For everyday carrying, dimensions, opening action and attachment layout are more useful than an unqualified strength claim. The key ring in the photograph is a separate connector; the Add-on specification does not establish its material or performance.

This example covers the maker’s illustrated key-carrying use. The cited page supplies no load rating to reproduce, and the words zinc alloy cannot supply one.
