As a widely known metal, bronze is a copper-tin alloy. However, certain amounts of aluminum and nickel may be added to obtain a custom bronze alloy to meet required physical and mechanical properties.
Bronze is a brittle, non-magnetic metal alloy with high ductility. Besides, it is an electrically conductive metal, and it has superior corrosion resistance.
Features & Applications
- Harder and more brittle than brass
- Less brittle than cast iron
- Melting point: 950°C
- Superior corrosion resistance (including seawater)
- Ideal for certain decoration applications (e.g. nodders, sculptures, musical instruments, etc.)
- Low metal-to-metal friction
- Electrical connectors
Manufactured Alloys / Grades
Specialized Bronzes and Uses of Bronze
Phosphor Bronze (Tin Bronze): A copper-alloy with the additions of tin (between 0,5% - 1,0%) and phosphorous (between 0,01%-0,35%). With its improved wear resistance and stiffness, phosphor bronze is an ideal material for the production of washers and springs.
Aluminum Bronze: A copper-alloy with the additions of aluminum (between 6%-12%), iron (6% maximum), and nickel (6% maximum). With its excellent toughness and superior corrosion resistance, aluminum bronze is widely used in marine applications, tools, or components that may be exposed to corrosive liquids and environmental conditions.
Copper-Nickel (Cupronickel): A copper-alloy with the addition of nickel (between 2%-30%). With its outstanding thermal stability, higher melting point than bronze, copper-nickel can withstand high temperatures without getting softened. Therefore, it is an ideal material for the production of electrical resistors and heating wires.
Nickel Brass (Nickel Silver): A copper alloy with the additions of nickel and zinc. Nickel addition provides the alloy with a silvery look. Although its strength is lower than other copper alloys, it is preferred for the aesthetic applications, such as fashion jewelry, and musical instruments.
