Reliable C51900 Phosphor Bronze Plate – ASTM B103 Alloy Sheet

Description

C51900 Phosphor Bronze Plate – CuSn6 High Strength Copper Alloy Sheet

C51900 phosphor bronze plate, also known as CuSn6 bronze sheet, is a premium-grade copper-based alloy engineered to deliver an exceptional combination of mechanical strength, spring properties, and corrosion resistance. Classified under the ASTM B103 standard, this alloy typically contains 6% tin, a small amount of phosphorus, and the balance copper. These elements enhance the alloy’s wear resistance, fatigue strength, and overall stability under cyclic loads.

Thanks to its unique metallurgical structure, C51900 bronze is widely used in high-performance industrial applications, particularly where durability, dimensional accuracy, and conductivity must be maintained over long service cycles.With its balance of conductivity, strength, and corrosion resistance, C51900 phosphor bronze plate is a top choice for OEM and custom part manufacturers.

🔩 Key Features of C51900 Alloy Plate

• High Strength & Elasticity
  Tensile strength ranges from 360–550 MPa, with excellent spring-back characteristics. Suitable for components requiring repeated flexing or load-bearing capacity.

• Excellent Cold Workability
  CuSn6 bronze sheets can be easily stamped, drawn, and rolled without cracking, making them ideal for complex shapes and thin-walled components.

• Superior Wear Resistance
  The tin component (6%) enhances anti-galling properties, making this material suitable for frictional components like washers, bushings, and bearings.

• Stable Electrical Conductivity
  Despite its strength, C51900 maintains good electrical conductivity, enabling use in electrical connectors, switch parts, and grounding terminals.

• Corrosion Resistant
  Performs well in humid, mildly acidic, or marine environments, especially compared to standard brass or commercial bronze.
