642 Bronze Chemical Properties
As a copper-based alloy, C64200 has excellent corrosion resistance when exposed to water or salt water environments. Its high copper content also makes it highly resistant to wear and tear from wear particles in its environment.
642 Bronze Mechanical Properties
With its high tensile strength and low thermal expansion rate, Bronze 642 can hold up under heavy loads over long periods of time without deforming or breaking down. It also has good fatigue strength, making it suitable for use in applications that experience high levels of vibration or shock loading levels.

Corrosion Resistance
As mentioned above, Alloy C64200 has excellent corrosion resistance when exposed to water or salt water environments, making it suitable for marine applications where exposure to corrosive elements could occur regularly. In addition to this, it also has good abrasion resistance, which makes it ideal for use in parts that come into contact with abrasive materials during operation, such as bearings or bushings that move against other surfaces during their operation cycle.
Heat Resistance
The melting point of 875°C (1627°F) makes Bronze 642 capable of withstanding higher temperatures than some other alloys without deforming or losing structural integrity over time due to extreme heat cycles experienced during operation at full speed under load conditions. This makes it ideal for use in engines operating at higher speeds over prolonged periods without requiring frequent replacement due to excessive heat damage caused by prolonged exposure at elevated temperatures over extended periods.
Heat Treatment
Heat treatment processes such as annealing can be performed on Bronze 642 in order to improve its strength and hardness while maintaining good ductility for improved performance when subjected to heavy loads during operation cycles over long periods of time without experiencing premature failure from fatigue due to extended operation cycles under load conditions.
Machining
Due to its relatively low melting point compared with other metals, bronze can easily be machined using standard tools available today, making it suitable for many fabrication processes such as drilling, tapping, turning, milling, etc.
Welding
Additionally, bronze can easily be welded using TIG MIG gas welding techniques depending on the application required, allowing greater versatility when creating custom components not available off-the-shelf.
