The CuZn31Si (H68) brass bushing with dimensions of 464272.5mm is a precision-made component designed for use in various mechanical applications. The brass alloy CuZn31Si, also known as H68, is a specific type of brass that exhibits excellent machinability, corrosion resistance, and strength. This alloy composition allows the bushing to perform well in both low and high-load environments.
The bushing's dimensions of 46mm in length, 42mm in width, and 72.5mm in height are tailored to fit specific mechanical assemblies or applications. This precise sizing ensures a snug and secure fit, minimizing the potential for vibration or misalignment.
The use of brass for bushings offers several advantages. Brass is a soft metal, which allows it to conform to mating surfaces, reducing wear and friction. It also has good electrical conductivity and thermal conductivity, making it suitable for applications where these properties are important.
In summary, the CuZn31Si (H68) brass bushing with dimensions of 464272.5mm is a reliable and durable component that is designed to meet the specific needs of various mechanical systems. Its material properties and precise dimensions contribute to its performance and longevity in various applications.
