Bronze Green Sand Casting

Overview Green sand casting is a versatile and cost-effective process for producing high-quality parts and components using various bronze alloys. The technique employs a mixture of sand, clay, and water to create molds for casting molten bronze, offering excellent precision and repeatability.
Bronze Alloy Grades The following table lists common international bronze alloy grades used in green sand casting:
Alloy Grade | Composition | Standard | International Equivalent |
---|---|---|---|
C83600 | 85% Cu, 5% Sn, 5% Pb, 5% Zn | ASTM B584 | SAE 40, EN CC491K |
C93200 | 83% Cu, 7% Sn, 7% Pb, 3% Zn | ASTM B505 | SAE 660, EN CC483K |
C95400 | 85% Cu, 11% Al, 4% Fe | ASTM B148 | EN CB331K |
C90700 | 88% Cu, 10% Sn, 2% Zn | ASTM B505 | EN CC493K |
C95500 | 80% Cu, 10% Al, 5% Ni, 5% Fe | ASTM B505 | EN CB752S |
C86300 | 60% Cu, 35% Zn, 3% Pb, 2% Fe | ASTM B584 | SAE J461, EN CB763K |
LG2 | 85% Cu, 5% Sn, 5% Pb, 5% Zn | BS 1400 LG2 | Similar to ASTM C83600 |
Processes The green sand casting process involves several critical steps:
- Pattern creation
- Mold preparation using green sand
- Melting and pouring of bronze
- Cooling and solidification
- Shakeout and removal of cast part
- Finishing and inspection
Typical Applications Bronze components produced via green sand casting are widely used in various industries:
Application | Industry |
Bearings and bushings | Automotive, Industrial Machinery |
Pump and valve components | Oil & Gas, Marine |
Decorative fixtures | Architecture, Art |
Tolerances and Finish Green sand casting provides the following tolerances and surface finishes:
Aspect | Specification |
Tolerances | ±0.25 mm to ±1.5 mm depending on part size |
Surface Finish | 125-250 RMS (microinches) |
