Phosphor Bronze Grade Comparison Guide
Use this as buyer guidance only. Final grade selection should follow temper, hardness, fatigue, conductivity, wear, machining, corrosion exposure and project specification.
| Grade | Common buyer reason | Typical forms | RFQ note |
|---|---|---|---|
| Phosphor Bronze C510 | spring grade phosphor bronze for strips, sheets and contacts | sheets, strips, coils, foils, rods and formed blanks | Share temper, hardness, thickness, width, coil or strip requirement and spring performance details where applicable. |
| Phosphor Bronze C521 | high-strength phosphor bronze for springs and fatigue-resistant parts | strips, sheets, coils, foils, rods, bars and spring blanks | Confirm required temper, tensile or hardness range, thickness tolerance and spring application details for C521 enquiries. |
| Phosphor Bronze C544 | free-machining phosphor bronze for rods, bars and bushes | round rods, bars, flats, bushes, bearings and machined blanks | Share rod diameter, bar size, bush dimensions, machining allowance, hardness and inspection requirements for C544 enquiries. |
Phosphor Bronze Naming and Reference Guidance
Phosphor bronze enquiries often include UNS, ASTM, EN, PB or customer drawing references. Rubinox reviews these references against grade, temper, hardness, spring requirement, product form and inspection scope before quoting.
| Buyer reference | How to review it | RFQ caution |
|---|---|---|
| C510 / C51000 | Spring phosphor bronze reviewed for strips, sheets, foils, contacts and formed parts. | Confirm temper, hardness, thickness, width and spring or contact requirement. |
| C521 / C52100 | High-strength phosphor bronze reviewed for spring and fatigue-resistant applications. | Share tensile or hardness range, temper, dimensional tolerance and application details. |
| C544 / C54400 | Free-machining phosphor bronze reviewed for rods, bars, bushes, bearings and wear parts. | Share rod diameter, bush ID/OD/length, drawing, machining allowance and inspection requirement. |
| PB1 / PB2 references | Can be reviewed at category level when the buyer shares exact standard, composition, temper and product form. | Do not treat PB1 or PB2 as automatic substitutes for C510, C521 or C544 unless approved by the buyer or project document. |
| EN / DIN / IS / customer references | Reviewed against the material standard, drawing and project specification. | Share complete reference documents where alternate-grade approval is required. |

What is the difference between C510, C521 and C544?
C510 is commonly reviewed for spring and electrical parts, C521 for higher-strength spring and fatigue applications, and C544 for free-machining rods, bushes, bearings and wear components.
Which phosphor bronze grade is used for springs?
C510 and C521 are commonly reviewed for spring, clip and contact applications. Final selection depends on temper, hardness, fatigue requirement, dimensions and buyer specification.
Which phosphor bronze grade is used for bushes and bearings?
C544 free-machining phosphor bronze is often reviewed for bushes, bearings, wear parts and machined components when the buyer specification calls for it.
What details are needed for a phosphor bronze quotation?
Share grade, temper, hardness, product form, thickness or diameter, width, length, quantity, standard, inspection requirement and delivery location. Drawings help for bushes or machined parts.
