Tin bronze and aluminum bronze are both types of copper alloys, but they differ in their composition and properties:
Komposition:
- Zinnbronze: Primarily composed of copper and tin, with tin typically ranging from 5% to 20%. It may also contain small amounts of other elements for specific properties.
- Aluminiumbronze: Contains copper and aluminum, with aluminum content usually ranging from 5% to 12%. It may also include small amounts of iron, nickel, or manganese.
Eigenschaften:
- Zinnbronze: Known for its excellent corrosion resistance, good wear resistance, and high strength. It’s often used in applications like marine hardware, musical instruments, and bearings.
- Aluminiumbronze: Offers superior corrosion resistance, especially in marine environments, along with high strength and good machinability. It’s often used in aerospace components, pumps, and valves.
Anwendungen:
- Zinnbronze: Commonly used in applications where good wear resistance is crucial, such as in bearings and bushings.
- Aluminiumbronze: Typically found in more demanding environments, like in the aerospace and oil industries, due to its robustness and resistance to harsh conditions.
In summary, the main differences lie in their alloying elements and resulting mechanical and corrosion-resistant properties, which dictate their respective applications.
