C85400 copper tubing is a typical aluminum-bronze cast tubing, renowned for its high strength, exceptional wear resistance, and excellent corrosion resistance. It contains a high proportion of aluminum, along with alloying elements such as iron and nickel. These elements combine to enable it to withstand extremely high mechanical loads and severe friction and wear, while also effectively resisting corrosion from the atmosphere, seawater, and various chemical media. Its performance far surpasses that of many common copper alloys.
Thanks to these comprehensive properties, this alloy tubing is ideal for use as critical components in demanding environments. It is commonly used in pumps, valves, and bearing sleeves in shipbuilding, as well as gears and screws in industrial applications. It is an ideal material for addressing equipment life challenges in heavy-load, low-speed, and highly corrosive environments.
