-65.61%C93200 bronze (UNS C93200, SAE 660) is a leaded tin bronze: copper with about 7% tin, 7% lead and 3% zinc. It is the bushing and bearing bronze: the lead makes it slide well against the shaft and machine very easily, and it carries load and resists wear. At PREMSA we CNC turn and mill it from your file, starting at a single part with an instant price.
C93200 (SAE 660) bronze properties: mechanical, physical and machining data to choose the material for your bushing or wear part.
Material Type

Good: withstands water, seawater, brine and oils
Surface Treatment
Usually as machined; it can be polished or plated
Common Forms
Solid bar, hollow bar (tube) and plate
Typical Applications
Bushings, bearings, thrust washers, wear plates and guides, pump bushings, machinery parts
Standards

What people ask most about C93200 SAE 660 bronze parts: what it is, composition, uses, why it is used for bushings, machining, lead, hardness, magnetism, corrosion, welding, equivalents, price and tolerances.
C93200 bronze is chosen for parts that rotate or slide against another and have to last: bushings, bearings, thrust washers and wear plates.
At PREMSA Industries we machine C93200 with CNC turning and milling from your file, from a prototype to production.
C93200 is chosen when the part has to rotate or slide against a shaft without wearing out.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —bore, outside diameter, length and bushing fits— we can hold ±0.025 mm (±0.001 in), and critical dimensions are checked in inspection.
C93200 is machined with CNC turning, CNC milling, drilling and tapping. The lead breaks the chip, so it runs fast and leaves a good finish on the bore, which is the working face of a bushing.
Because it slides well, carries load and machines easily, C93200 is used in many parts made with CNC machining.
C93200 is usually the right choice when the part rotates or slides against a shaft and has to last.
