Tin Bronze Plate – Process & Quality Assurance Statement
Our tin bronze plates are produced to deliver reliable strength and wear performance in applications where heavy loads and sliding contact demand materials that won't fail prematurely.
Key process features
Manufacturing uses proven casting and finishing techniques to achieve dense, uniform plates suitable for machining into critical components:
●Alloy Melting: High-grade copper and tin are melted with precise additions to achieve the target composition and fluidity.
●Casting Process: Continuous or static casting produces slabs with controlled cooling to minimize porosity and segregation.
●Hot Rolling: Initial reduction refines the structure and achieves intermediate thickness.
●Annealing: Heat treatment relieves stresses and optimizes machinability.
●Cold Finishing: Final rolling or leveling ensures flatness and precise thickness.
●Surface Preparation: Plates are milled or ground as required for smooth faces.
●Cutting & Protection: Custom sizing with clean cuts; surfaces lightly oiled to prevent oxidation during storage and shipping.
Quality control system
● Complete traceability from raw material charge to finished plate
● Mill test reports provided with every batch
● Sample retention ≥3 years for third-party review (SGS, BV, TÜV, etc.)
● 100% inspection of key parameters:
• Chemical composition (optical emission spectrometry)
• Mechanical properties (tensile, hardness, and compressive testing on samples)
• Dimensional accuracy (micrometers and flatness gauges; typical tolerance ±1% on thickness)
• Surface quality and defects (visual + ultrasonic on thicker plates)
• Internal soundness (ultrasonic examination standard)
● Internal standards meet or exceed ASTM B505 requirements. Typical C90500 properties: Tensile strength ≥380 MPa, High resistance to pounding and wear, Reliable performance in high-pressure bearing applications.
● ISO 9001:2015 certified foundry ensures every tin bronze plate offers the consistent quality and durability needed for your demanding projects.
