Bronze bushings are commonly used in various industrial applications due to their excellent durability, resistance to wear, and ability to operate in harsh environments. The most frequently used bronze bushing materials include alloys that combine copper with elements like tin, zinc, aluminum, and lead. Each alloy has specific properties that make it suitable for particular applications, ranging from high-load capacity and corrosion resistance to excellent machinability and longevity. Some of the most common bronze bushing materials include C93200 (SAE 660), C83600 (SAE 40), C86300 (SAE 430B), C95400, C90500, C86200 (Manganese Bronze), and C95200 (Aluminum Bronze). Each of these alloys brings a balance of strength, hardness, and elongation, making them suitable for use in machinery, automotive parts, and heavy-duty industrial applications.
