Innovative copper filtration solutions
As copper casting manufacturers demand higher purity standards for electrical components, architectural elements, and industrial parts, SF-Foundry responds with its zirconia (ZrO₂) foam ceramic filters – engineered to outperform conventional alumina and carbon-based solutions.
The Copper Filtration Challenge
Copper’s high fluidity and oxidation tendency require filters that:
- Withstand 1,300°C+ molten metal temperatures
- Capture micron-scale Cu₂O inclusions without clogging
- Maintain structural integrity during high-volume pours
SF-Foundry zirconia formula delivers three key advantages for discerning foundries:
SF-Foundry Ceramic Filters Technological Edge
1️⃣ 1600°C Thermal Shock Resistance
30% longer service life vs. standard alumina filters in prolonged copper alloy casting
2️⃣ Ultra-Stable Chemical Structure
Zero reactivity with sulfur/phosphorus in specialty bronzes
3️⃣ Customizable Various Shapes
Optimized flow rates for thick-wall sculptures vs. thin-wall electronic components
Proven Industrial Applications
- Electrical Engineering: Reduced porosity in busbar castings improves current-carrying capacity
- Art Foundries: Mirror-finish surfaces on large bronze statues
- Plumbing Fixtures: high slag capture rate in high-zinc brass production
