What is C95400 Aluminum Bronze?
C95400 aluminum bronze, also called CDA 954, 954 bronze, or 9C aluminum bronze, is one of the most widely used cast aluminum bronze alloys for heavy-duty industrial components. It offers higher strength than standard leaded bearing bronze, along with strong resistance to wear, fatigue, shock loading, and deformation.
U.S. buyers commonly specify C95400 when a bushing, bearing, gear, wear plate, valve component, or pump part needs more load capacity than C93200 / SAE 660 can provide. It is a practical choice for high-load, low-speed service where strength and wear resistance are more important than maximum embeddability.
