Frequently Asked Questions
C62400 Aluminum Bronze is commonly used for heavy-duty bearings, pump rods, valve stems, and shafts, nuts and bolts. Higher aluminum content for increased strength. Suitable for heavy-duty applications requiring high wear resistance.
C62400 has a machinability rating of 20 (on a scale where free-cutting brass C36000 = 100). This indicates lower machinability, requiring specialized tooling and slower cutting speeds.
C62400 has a tensile strength range of 85–100 ksi. This high strength makes it suitable for heavy-duty structural and load-bearing applications.
Yes, C62400 offers excellent corrosion resistance. The aluminum content forms a protective oxide layer that provides outstanding resistance to seawater, chemicals, and atmospheric corrosion.
C62400 is a wrought alloy. It is available as bar stock, rod, plate, sheet, and tube.
