Bronze is one of the oldest and most popular metals in the world, only next to gold and silver. It’s prized throughout history for its many valuable qualities, which allow it to be utilized for a wide range of applications. However, unlike gold and silver, it is not a pure metal, but rather an alloy of copper and tin, two non-ferrous metals with an amazing list of beneficial properties of their own.
Different amounts of copper and tin can be combined to form different types of bronze. Sometimes, other metals are added as well to enhance existing properties or produce new ones, making it suitable for more than few applications. The following are the different types of bronze and their uses.
Phosphor Bronze
The amount of tin in typical bronze ranges from 10% to 12%. This combination already makes bronze strong and corrosion-resistant. However, it may not have enough wear resistance and stiffness required in situations where fatigue and chemical corrosion are commonplace, such as propellers operating under seawater or even dental bridges. By adding a small amount of phosphorous and reducing the amount of tin to balance out excess, bronze’s wear resistance and stiffness are increased.
