Alkali-Free Fiberglass Filter Mesh

Alkali-Free Fiberglass Filter Mesh (GL Series)

Manufactured from high-strength, high-modulus alkali-free fiberglass woven fabric with special surface treatment. Specifically designed for aluminum melt filtration, with a maximum operating temperature of 900°C.

Applications

• Automotive and motorcycle wheel hubs
• Steering knuckles, cylinder heads, pistons
• Aluminum alloy castings and precision die-cast parts
• Effectively removes gas bubbles, slag, and inclusions from aluminum melt

Advantages

• Most economical filtration solution for aluminum alloys
• Reduces casting defects such as porosity and slag inclusions
• Does not affect mechanical properties of castings
• Reduces iron contamination caused by wire mesh use
• Easy to recycle, lowering overall production costs
