Yes, absolutely. Our fiberglass filter mesh is designed for easy customization. You can cut it to any shape using sharp scissors or utility knife without compromising filtration performance. The flexible mesh conforms to irregular shapes and curved surfaces, unlike rigid ceramic filters. For complex geometries, we recommend making cardboard templates first, then cutting mesh to match. Leave 10-15mm overlap at edges for secure positioning. Many customers maintain a few standard sizes in inventory and cut custom shapes as needed, reducing inventory complexity.

Our Standard Series withstands continuous operation up to 800°C (1472°F), suitable for most aluminum casting applications (typical pouring temperatures 680-750°C). The High-Temperature Premium Series extends resistance to 1000°C (1832°F) for specialized applications including aerospace aluminum-lithium alloys and extended holding times. Short-duration temperature spikes 50-75°C above rating are tolerable, but sustained operation above maximum rated temperature will cause fiber degradation and reduced filtration efficiency. Always select the appropriate series based on your actual pouring temperature plus 50-75°C safety margin.

No. Our fiberglass is manufactured from E-glass composition specifically selected for chemical compatibility with molten aluminum. The glass fibers do not dissolve, react with, or contaminate aluminum alloys. Extensive testing including spectrographic analysis of filtered metal shows zero increase in silicon, calcium, or other glass components. The fiber surface treatment is non-reactive and thermally stable.

Yes, with temperature considerations. The filter works excellently for magnesium alloys (similar temperatures to aluminum), zinc alloys (lower temperatures, very safe), and lower-temperature copper alloys like bronze and brass (verify specific alloy temperature). For higher-temperature metals like cast iron (1200-1400°C) or steel (1500-1600°C), our fiberglass mesh exceeds safe operating temperature. For ferrous metals, we recommend our specialized ceramic-based filtration products. Contact our technical team with your specific alloy and temperature; we’ll confirm compatibility or recommend appropriate alternative.
