Brass is an alloy, made up of roughly half copper and half zinc, which has a nice yellow color. We usually strike medals from a brass alloy of 70% copper and 30% zinc. Brass with a higher copper content will tend to be more reddish in color, such a special brass alloy with higher copper content (known as semi-oro) can be requested for distinguished plaques. We cut medals' blanks from 1 to 5 mm thick brass sheets. Brass plates used for plaques and sign plates are cut from 0.6 or 1 mm thick brass sheets.
