Bronze Casting Products & Specifications (Marine/Industrial Focus)

Product Range (Global Marine/Industrial Applications)

We provide custom bronze castings for global industries, focusing on components that require excellent corrosion resistance and wear resistance in harsh marine/industrial environments:

  • Marine Hardware: Propellers (C95400), stern tubes, shaft sleeves (C90500), marine valve bodies (C90300) - seawater corrosion resistant (5000+ hours salt spray test, ASTM B584 compliant)
  • Valve & Pump Parts: Valve bodies (C90300), valve cores, pump impellers (C95400), pump casings - high wear resistance (wear rate 0.001mm/km for C90500, 3x better than steel)
  • Automotive Parts: Bearings (C93200), bushings, gears, engine components - low friction coefficient (ideal for global automotive suppliers, SAE 66 standard)
  • Industrial Machinery: Hydraulic components (C95400), gears, worm gears, wear plates - high load capacity (450MPa tensile strength, structural grade)
  • Art & Decoration: Bronze sculptures (C90300), decorative hardware, architectural elements - excellent polishability (patina-resistant finish, Ra 1.6micron achievable)
  • Custom Components: OEM casting per global customer drawings (CT7-8 precision, 0.1kg - 500kg weight range, 4-6 weeks lead time)

Material Specifications (Full Certification & Traceability)

We select high-quality bronze raw materials with stable chemical composition, full certification and spectrometer testing for global clients (per ASTM B584 standards):

  1. Tin Bronze: C90300 (SAE 65, 90Cu-10Sn) - excellent seawater corrosion resistance, C90500 (SAE 660, 88Cu-8Sn-4Zn) - high wear resistance (0.001mm/km wear rate)
  2. Aluminum Bronze: C95400 (SAE 630, 85Cu-10Al-5Fe) - 450MPa tensile strength & 5000+ hours salt spray resistance, C95500, C95800 (ASTM B584 compliant)
  3. Silicon Bronze: C65500, C65800 - excellent weldability & corrosion resistance (ideal for offshore marine applications, BS EN 1982 certified)
  4. Lead Bronze: C93200 (SAE 66) - self-lubricating properties for bearings/bushings (global industrial standard, low friction coefficient)
  5. Custom Bronze Alloys: Tailored according to international customer requirements (corrosion/wear/strength performance for specific marine/industrial environments)

All materials pass strict spectrometer chemical composition testing and tensile strength verification (450MPa for C95400), ensuring stable quality for marine/industrial applications worldwide with full material traceability.

Technical Parameters (International Marine Standards Compliance)

Our bronze casting adheres to strict global technical standards to meet high-end marine/industrial application requirements:

  • Dimensional Accuracy: CT7-8 (ISO 8062) - ±0.1mm tolerance for critical marine propeller/valve dimensions (global precision standard)
  • Surface Finish: Ra 3.2-6.3micron (Ra 1.6micron available with precision polishing and buffing for decorative/art applications)
  • Casting Weight: 0.1kg (micro-components) - 500kg (large marine propellers for global shipyards, ASTM B584 certified)
  • Wall Thickness: Minimum 2mm (uniform thickness control with ±0.2mm tolerance - no porosity for pressure applications)
  • Heat Treatment: Solution annealing, quenching, tempering (optimizes hardness up to 180 HB for C95400)
  • NDT Testing: RT, UT, MT, PT (per ASTM E165 for marine critical components - global safety standard for shipbuilding)
  • Density: 8.8g/cm3 (good weight-to-strength ratio for structural marine applications, 450MPa tensile strength)
