Flamingo materials have a high interconnecting structure with a uniform porous surface and small wall thickness, ensuring great permeability for a given pore size.
The permeability coefficient of Flamingo sintered bronze filter elements can be calculated using the following formula (Darcy's Law):
| Property | Value |
|---|---|
| Chemical Composition (Nominal) | Cu-89%, Sn-11% |
| Density | 5-6.5 gm/cc |
| Porosity by Volume | 30-45% |
| Coefficient of Linear Expansion | 18.3 x 10-6 °C |
| Temperature Suitability | In oxidising gasses (air) up to 180°C or in reducing gasses up to 400°C |
| Grade | Average Filtration Level (micron) | Coefficient of Permeability (x10-3 cm) |
|---|---|---|
| F80 | 75-95 | 1500 |
| F40 | 50-65 | 1000 |
| F25 | 25-35 | 250 |
| F15 | 14-20 | 75 |
| F10 | 10-12 | 25 |
| F5 | 5-8 | 10 |
| F1 | 2-8 | 3 |
