Description
🔩 C54400 Phosphor Bronze Plate – High-Strength Alloy for Industrial Machining Uses
The C54400 Phosphor Bronze Plate is a top-grade, high-performance bronze alloy known for its excellent machinability, high strength, and fatigue resistance. Conforming to the ASTM B103 standard, this alloy—also known as free-cutting phosphor bronze—is a favorite among engineers and machinists working in aerospace, electronics, marine, and high-reliability mechanical systems.
🔍 Key Features of C54400 Phosphor Bronze Plate
✅ 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.
✅ High Strength and Toughness
With a tensile strength range of 450–620 MPa and good yield properties, this plate performs reliably under mechanical stress and vibration, especially in precision mechanical assemblies.
✅ Good Corrosion Resistance
Suitable for use in mildly corrosive environments including salt spray, fuel vapor, lubricants, and fresh water, the C54400 alloy offers longevity in harsh service conditions.
✅ Dimensional Stability
This alloy maintains tight tolerances and flatness even under thermal cycling and post-machining operations, making it a preferred choice for CNC shops and OEMs.
✅ Standardized Quality
All materials are produced to ASTM B1032/B1032M-25 specifications, ensuring consistent physical and mechanical properties.
🧪 Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Copper (Cu) | 88.0 – 91.0 |
| Tin (Sn) | 3.3 – 4.2 |
| Lead (Pb) | 1.5 – 4.5 |
| Zinc (Zn) | 0.0 – 1.0 |
| Iron (Fe) | ≤ 0.25 |
| Phosphorus (P) | 0.03 – 0.35 |
This composition gives the C54400 Phosphor Bronze Plate its distinctive machinability, wear resistance, and surface finish capabilities, especially in high-speed operations.
📊 Mechanical Properties
| Property | Typical Value |
|---|---|
| Tensile Strength | 450 – 620 MPa |
| Yield Strength (0.5% ext.) | 250 – 350 MPa |
| Elongation | 10 – 25% |
| Hardness (Rockwell B) | 75 – 90 HRB |
| Density | 8.75 g/cm³ |
| Electrical Conductivity | ~15% IACS |
| Thermal Conductivity | ~70 W/m·K |
