Metals - Bronze and Brass






Bronze is a combination of copper and tin, usually 88 percent copper and 12 percent tin. Commercial bronze, or brass, is generally 90 percent copper and 10 percent zinc. Bronze only oxidizes on its surface, and once the surface oxidizes, the thin oxide layer protects the underlying metal from further corrosion.


Bronze is generally 10 percent heavier than steel while being softer and weaker. It better resists corrosion and metal fatigue than steel, and also conducts heat and electricity better. Oil rubbed bronze features a surface that was chemically darkened to simulate aging bronze. This finish is very dark and can vary from a deep chocolate brown to a dark gray, and it usually has copper undertones.

There is a wide variety of coloration of the oil rubbed bronze finish. To ensure the bronze cabinet pulls Tidal Pulls delivers are right for you, please send us a color sample so that it can be matched.
