660-2000 has a 2 in rod diameter. The material is 660 Bronze Copper Alloy 932.
660 Bronze is known as “bearing bronze” because it is most commonly used in bushing and bearing applications. While it is easily machined, the bronze alloy is hard, strong, and resistant to wear. It is also less dependent on lubrication than other alloys and has reasonable corrosion resistance to seawater and brine.
660 Bronze is used for machining bearings, bushings, wear strips, and plates. This grade of bronze is used in pump, cylinder, and machine tool applications.
- Good anti-friction properties
- Ample strength and hardness
- Adeqaute ductility
- Excellent machinability
Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.
