FULITE glass fiber filtration mesh for molten aluminum can provide various specifications—from large-opening, high-flow types to fine, high-filtration types—according to different aluminum alloy processes, molten aluminum flow rates, and cleanliness requirements.

Key Differences Between Models:

  • Mesh Opening Size

  • Open Area

  • Unit Weight

  • Weave Type

  • Thickness

  • Molten Aluminum Flow Capacity

Therefore, a suitable filtration grade can be selected according to actual casting conditions.

Model Specification Introduction
Product Model Weight (g/m²) Weave Opening Size Open Area Thickness Filtration Positioning Product Features & Recommended Applications
310RT-AC 125 Leno 2.82 mm² 70% 0.30 mm Large Opening / High Flow Type

Largest opening and highest open area in the series, fast molten aluminum flow speed, low flow resistance.

Recommended: High flow molten aluminum, front-end coarse filtration.
410-AC 358 Plain 2.15 mm² 55% 0.70 mm High Flow Filtration Type

Increases filtration capability while maintaining a high open area, balancing flow rate and impurity trapping.

Recommended: Aluminum ingots, aluminum rods, general continuous casting.
411-AC 399 Plain 1.15 mm² 46% 0.65 mm Standard Filtration Type

Balanced filtration precision and molten aluminum fluidity, suitable as standard specification.

Recommended: General aluminum alloy casting and standard molten aluminum filtration.
412-AC 435 Plain 0.94 mm² 44% 0.70 mm Medium Fine Filtration Type

Enhanced interception capability for finer oxides and non-metallic inclusions.

Recommended: Casting processes with higher requirements for cleanliness.
413-AC 470 Plain 0.52 mm² 38% 0.70 mm Fine Filtration Type

Fine mesh design for small oxides; filtration area and flow rate must be balanced during use.

Recommended: Precision aluminum castings, high-cleanliness molten aluminum.
418-AC 312 Plain 0.39 mm² 20% 0.35 mm High Precision Fine Type

Finest mesh and lowest open area, focusing on improving filtration accuracy.

Recommended: High-quality aluminum alloy castings and high-cleanliness requirements.
A smaller opening size does not necessarily mean it is more suitable for molten aluminum filtration; it is not simply a matter of pursuing the smallest opening size.

Trade-off Principle:
Smaller Opening Size → Higher Filtration Capacity → Lower Open Area → Increased Flow Resistance

Factors to Consider for Selection:
Therefore, correct model selection should simultaneously consider:
Molten Aluminum Processing Volume × Molten Aluminum Temperature × Pouring Time × Filtration Area × Inclusion Amount × Product Quality Requirements

Technical Support:
FULITE can assist in evaluating the appropriate opening size, open area, weave, and fiberglass filter model based on your on-site process conditions, achieving an optimal balance between molten aluminum cleanliness and production efficiency.
