Many people often confuse traditional Bronze Plaques to Brass due to the similar colouring.
Brass is an alloy of copper (approx 65%) and zinc with variations in percentages depending on the brass type purchased. These products are commonly used for engraved signage that is placed indoors.
Bronze is principally an alloy of copper (approx 85%) and tin. Bronze is commonly used for casting purposes for signage and can be placed either indoors or outdoors.
