What is C62200?
C62200 is a wrought aluminum bronze rod and bar alloy covered by ASTM B150, used where higher strength than C61400 is needed. It delivers 655 MPa tensile strength, 330 MPa yield, 20 % elongation and 170 HB (90 HRB), with service to about 300 °C and good resistance to seawater, wear and galling in bearing and gear applications. Limits are a machinability rating of roughly 30 on the free-cutting brass scale, poor cold formability, and the need to hot work at 700–850 °C. Nickel-aluminum bronzes are the alternative when still higher strength is required. C62200 has a density of 7.53 g/cm³ (0.272 lb/in³), lighter than 96% of copper alloy grades. It melts at 1,027°C (1,881 °F). C62200 has a yield strength of 330 MPa (47.9 ksi) and a tensile strength of 655 MPa (95 ksi) — stronger than 69% of copper alloy grades. Elongation at break is 20% and the elastic modulus is 117 GPa (17 Msi).

Working with C62200
Is C62200 easy to machine?
Machines like a tough, gummy-to-abrasive bronze: rigid setup, positive-rake sharp carbide, moderate speed with heavy feed and flood coolant; expect ~20–30 % of free-cutting brass throughput and short tool life on the hard γ2-containing tempers.
Can C62200 be welded?
GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well if the alumina film is wire-brushed off and interpass temperature is kept low; avoid slow cooling through 550–350 °C and do not oxyacetylene weld or solder.
Can C62200 be formed, bent or molded?
Hot work at 700–850 °C (forge, extrude, bend); cold formability is poor, so limit cold bends to generous radii or anneal first, and use a 600–650 °C temper anneal to relieve stresses.
C62200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

| Al | 11 – 12 | 11.5 |
| Fe | 3 – 4.25 | 3.6 |

What surface finishes work on C62200?
Not anodizable — takes a fine mechanical polish and buffs to a golden lustre that self-passivates; electroplating (Ni strike first) or PTFE/dry-film lubricant coatings are used for wear parts, and no painting is normally needed for marine service.

C62200 — frequently asked
What is C62200 used for?
C62200 is typically used for gears, bushings, marine hardware and pump shafts. In short: stronger than C61400; wear-resistant marine bronze; hot-forged bar and rod.
What is the yield strength of C62200?
C62200 has a typical yield strength of 330 MPa (47.9 ksi) and a tensile strength of 655 MPa (95 ksi) — stronger than 69% of copper alloy grades. Strength varies by condition: see the 6 listed tempers.
Is C62200 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 67% of copper alloy grades). Machines like a tough, gummy-to-abrasive bronze: rigid setup, positive-rake sharp carbide, moderate speed with heavy feed and flood coolant; expect ~20–30 % of free-cutting brass throughput and short tool life on the hard γ2-containing tempers.
Can C62200 be welded?
Yes — weldability is rated good (65/100). GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well if the alumina film is wire-brushed off and interpass temperature is kept low; avoid slow cooling through 550–350 °C and do not oxyacetylene weld or solder.

What is the maximum service temperature of C62200?
C62200 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C62200-M30 and C62200-H04?
M30 is the default condition — standard stocked condition for C62200 rod, bar and shapes; best balance of strength, ductility and price. H04: pick for close-tolerance cold-drawn bar and the highest as-supplied strength/hardness without heat treatment. Yield strength is 330 MPa in M30 versus 450 MPa in H04.
