Aluminum-magnesium luggage

Aluminum magnesium luggage — the material that made hard cases lighter

Aluminum-magnesium (Al-Mg) alloy is the shell material CLK uses for the premium end of the hard-case range. It combines the dent resistance of metal with a lighter weight than pure steel frames, which is why it is the default choice for business travelers who check bags regularly.

What to check when sourcing Al-Mg cases

Frame: a curved aluminum frame keeps the two shells aligned after impact — CLK pairs it with 1.0 mm all-aluminum trolley tubes.
Locking: two TSA-approved latch locks per case allow customs inspection without damage.
Corners: stainless steel protectors (20/24-inch) or aluminum alloy corners (28-inch sports edition) absorb the worst impacts.
Weights: reference set KLW003 runs 3.8 kg (20″), 4.92 kg (24″), 5.4 kg (28″) — confirm your target spec against airline limits.

Start with the flagship set: aluminum-magnesium luggage KLW003 (20/24/28″), the single-model KLW001, or the oxidation-finish full aluminum case with oxidation process for a distinctive color.
