Commercial Bronze 220 / C220 / C22000
ASTM B36, BS 2870 CZ101, EN CW501L
Farmer’s Copper Ltd. maintains an extensive inventory of C220 Commercial Bronze Alloy in plate and sheet form. The alloy has a high capacity for being cold worked and does not harden as rapidly as higher zinc alloys, 240 and 260, thus requiring fewer anneals between operations. Exposure to high sulfide media should be avoided.
Farmer’s Copper Ltd. has been serving the metal industry for over 90 years. Contact one of our knowledgeable sales staff today to help you with your C22000 Commercial Bronze needs! We offer material to be cut to your specifications by any of our precision plate saws, bar saws, shears, and water jets. Holding tolerances as close as +/- .005”, we eliminate excess machining and above all time.
Standard Sizes
- Sheet - .032”, .064”, .125”
- Plate - .190”, ¼”, 3/8”, ½”
