About

Bronze (90% copper, 10% tin) is a copper-tin alloy with a warm reddish tone and an antique look, harder and stronger than brass and more resistant to tarnish.

Cast bronze typically reaches about 300–550 MPa tensile strength but can be brittle in thin or delicate sections (minimum walls about 0.6–0.8 mm, details about 0.35–0.4 mm).

It is an affordable alternative to precious metals but is not rated as biocompatible.

Bronze is a good option for antique-looking jewelry, miniatures, sculptures, and test pieces before committing to gold or silver.
