Description
๐ฉ C54400 Leaded Phosphor Bronze Plate
The C54400 Phosphor Bronze Plate is a leaded free-cutting phosphor bronze selected for machining stock. ASTM B103 includes C54400 flat products; confirm the ordered temper, chemistry and mechanical acceptance requirements for the component.
๐ Key Features of C54400 Phosphor Bronze Plate
โ
Excellent Machinability
As one of the most free-machining copper alloys, the C54400 Phosphor Bronze Plate is ideal for turning, milling, drilling, and threading with minimal tool wear and excellent chip formation.
โ
High Strength and Toughness
The catalogue lists tensile strength of 450โ620 MPa. Confirm the ordered temper, section and mechanical test requirements for stress or vibration service.
โ
Good Corrosion Resistance
For salt spray, fuel vapor, lubricant or fresh-water exposure, specify the medium, service conditions and corrosion acceptance requirements.
โ
Dimensional Stability
Specify dimensional tolerances, flatness and any thermal-cycling tests for the machined component and ordered delivery condition.
โ
Standardized Quality
ASTM B103/B103M covers C54400 flat products. Confirm the ordered edition, temper and required inspection documents.
๐งช Chemical Composition (Typical)
The current catalogue reference table is product information, not certified grade acceptance ranges. For order acceptance, confirm the C54400 grade standard and the batch material certificate, including tin, lead, zinc, phosphorus and other specified elements.
| Element | Content (%) |
|---|---|
| Copper (Cu) | 88.0 โ 91.0 |
| Tin (Sn) | 3.3 โ 4.2 |
| Lead (Pb) | 1.5 โ 4.5 |
| Zinc (Zn) | 0.0 โ 1.0 |
| Iron (Fe) | โค 0.25 |
| Phosphorus (P) | 0.03 โ 0.35 |
For C54400 Phosphor Bronze Plate, establish chemistry acceptance from the ordered specification and batch analysis; select machining and finish conditions for the component.
๐ Mechanical Properties
| Property | Typical Value |
|---|---|
| Tensile Strength | 450 โ 620 MPa |
| Yield Strength (0.5% ext.) | 250 โ 350 MPa |
| Elongation | 10 โ 25% |
| Hardness (Rockwell B) | 75 โ 90 HRB |
| Density | 8.75 g/cmยณ |
| Electrical Conductivity | ~15% IACS |
| Thermal Conductivity | ~70 W/mยทK |
Thanks to these properties, the C54400 Phosphor Bronze Plate is ideal for load-bearing components requiring close dimensional control and stable physical behavior during processing and usage.
