C52400
C52400 is a copper-tin alloy that contains approximately 10% tin (Sn) and the remaining balance being copper (Cu). It falls under the category of tin bronze alloys, also known as Phosphor Bronzes. The alloy is also sometimes referred to as CuSn10, which is its designation according to the Unified Numbering System (UNS).
C52400 exhibits a combination of good mechanical properties, high wear resistance, and excellent corrosion resistance. It is often chosen for applications that require high strength and good frictional properties. The addition of tin to copper imparts increased hardness and wear resistance to the alloy.
C52400 strips are commonly used in a variety of industries and applications. Some typical uses include electrical connectors, bushings, bearings, thrust washers, gears, and valve components. The alloy's properties make it suitable for applications where low friction, high load-bearing capacity, and resistance to wear and corrosion are required.
It's important to note that specific mechanical and chemical properties, as well as manufacturing standards, may vary depending on the specific supplier or industry requirements. Therefore, if you have more specific requirements or need detailed information, it is recommended to consult the relevant technical specifications or reach out to the manufacturer for accurate and up-to-date information.
