C14500 Uses
Additionally, its machinability makes it helpful in creating intricate shapes or designs needed for complex parts such as gears or bearings. Finally, its weldability allows for the easy joining together of multiple parts into one cohesive piece without losing any structural integrity during the
Corrosion Resistance
As previously mentioned, Copper C145 has excellent corrosion resistance making it ideal for use in marine and industrial applications where exposure to harsh environmental conditions is common. It can also be used in electrical components due to its low sulfur content, which ensures minimal electrical resistance when conducting current through the material.
Heat Resistance
Copper C145 offers good heat resistance making it suitable for use in high-temperature environments where temperatures exceed 650°C (1200°F). The alloy can retain its shape at these temperatures without deforming or becoming brittle like some other metals would at higher temperatures.
Heat Treatment
Depending on the application requirements, this material can be treated with various heat treatments to improve its strength and hardness further.
Machining
In terms of machining capabilities, these materials can easily be cut using standard cutting tools such as drills and saws; however, they require extra care due to their tendency to work hard during fabrication processes, leading to increased tool wear rates over time if not monitored closely enough during production runs.
Welding
As far as welding goes, these alloys are fairly easy to join together using either MIG or TIG welding techniques; however, the flux should always be used when possible, as this will ensure a strong joint between two pieces of metal without sacrificing any structural integrity during the process itself.
