As a representative of high-performance tin bronze alloys, C83800 copper plate has a balance of strength and ductility. Its tensile strength exceeds 200MPa, its yield strength is above 90MPa, and it maintains an elongation of 25%. This unique mechanical combination makes it an ideal material for transmission parts such as bearings and gears. The material has a low shrinkage rate during the casting process, can accurately form complex components, and is not prone to burrs during cutting, which significantly improves machining efficiency.
The copper alloy is particularly resistant to environmental corrosion. It can form a dense oxide film in humid air, fresh water and seawater media, effectively delaying the corrosion process. It is particularly suitable for the manufacture of parts such as ship accessories and steam valves that are exposed to harsh working conditions for a long time. With excellent welding performance, it can meet the dual needs of material reliability and process adaptability in different industrial scenarios.
