About

Brass is a tin brass (80% copper, 15% zinc, 5% tin) that reproduces fine detail and is a lower-cost alternative to gold and silver.

When polished, brass is smooth and shiny and when unpolished, it is matte, rough, and antique in appearance. Cast brass is fairly ductile and dense, but it tarnishes and develops a patina over time and is not rated as biocompatible.

Brass is a good option for jewelry, miniatures, and test pieces before committing to gold or silver.
