What metals are used to make silver and gold katana tsuba?
Updated Mar 2026
Most silver-tone tsuba in contemporary collectible katana are cast or forged from zinc-aluminum alloys, brass with a silver-plate finish, or polished iron alloys treated to hold a bright appearance long-term. Gold-tone guards typically use brass, bronze, or gold-lacquered alloys rather than solid precious metal. Historically, Japanese smiths used shakudo (a copper-gold alloy) and shibuichi (copper-silver alloy) for their rich, muted patinas, and some high-end reproduction pieces reference those traditions with similar copper-base alloys. For display purposes, the key quality indicator is surface finish consistency and the sharpness of relief engraving — well-cast guards show clean edges on dragon scales, chrysanthemum petals, and lattice cutouts with no blurring or flash marks from the mold.
