Steel .223/5.56 Casings — An Uncommon Material
Looking for something more distinctive than ordinary brass? These genuine once-fired .223 and 5.56 casings are made from naturally gray, magnetic steel, giving jewelry, steampunk art, mixed-media pieces and display projects a strong industrial character.
Every casing is cleaned, wiped and individually inspected before packing. Choose 5 pieces to experiment with an idea or select 15, 25 or 50 for coordinated projects and larger builds.
Looking for the standard brass version, or a nickel-plated finish instead? See our brass version or our nickel version.
Why makers choose them
- Naturally gray steel: A darker, more industrial alternative to traditional brass or bright nickel-plated finishes.
- Genuinely magnetic: Every casing is steel and responds to a magnet, opening up display and design possibilities that brass cannot provide.
- Prepared with care: Each casing is tumbled clean, wiped and individually inspected for a consistent, project-ready lot.
- Flexible quantities: Available in packs of 5, 15, 25 and 50, starting at $8.95 for five pieces.
Popular uses
- Steampunk and industrial artwork
- Mixed-media assemblages and shadow boxes
- Jewelry and accessories designed around an intact casing
- Magnetic displays and interactive art
- Epoxy and resin projects
- Prototypes, samples and material experiments
- Collectible material and finish comparisons
A quick note for makers: Steel gives these casings their distinctive strength, magnetic quality and industrial appearance, but it is tougher to cut and drill than brass, aluminum or nickel-plated brass. You may need blades or bits specifically designed for working with heavier metals.
Popular Uses
- Steampunk & Industrial Art: the gray, utilitarian look reads differently than polished brass.
- Bullet Jewelry & Accessories: a distinctive alternative finish for earrings, pendants, and keychains.
- Magnetic Craft Projects: unlike brass, these are genuinely magnetic — a fun, functional property for certain builds.
- Collectors: a talking-point piece for anyone interested in ammunition components and materials.
