chromoly

Chromium-molybdenum steel

Chromoly is a steel alloy containing chromium and molybdenum, prized for its high strength-to-weight ratio.

It appears most often in bicycle frames, roll cages, and aircraft tubing—applications where strength matters but weight must stay low: a chromoly frame, chromoly handlebars.

Short for chromium-molybdenum steel.
