CDA 953 Bronze Casting
CDA 953 Bronze Casting – C95300 | Low Iron Aluminum Bronze
CDA 953 is the CDA designation for C95300, a low-iron aluminum bronze. Lower iron content provides better machinability (35%) and a softer microstructure than AB1 (CDA 952), making CDA 953 suitable for applications where ease of machining outweighs the need for maximum strength. Tensile strength 480 MPa min per ASTM B148.
