Detailed Product Description
Alumina Foamed Ceramics:
Foamed Ceramics filter have the characters of light, high strength , large specific surface areas, high porosity , excellent heat resistant and chemical corrosion resistant. With the distributing pores net structure, they are able to increase the surface area, and absorb the thin waste, so the liquid metal can be molding safety.
| Increased Fluidity | Removal of inclusions makes the metal more fluid, resulting in easier mold fill, better cast structure, and better thin section castability. |
| Reduced Mold and Die Wear | Removal of inclusions and other nonmetallic debris from the melt reduces die soldering and mold-metal interaction, which degrades the mold surface and service life. |
| Longer Tool Life | Oxide as well as intermetallic inclusions create hard spots that damage tools in machining and finishing operations. Filtration reduces tool wear and increases productivity. |
| Fewer Rejects | Inclusions nucleate porosity, create hot tears during solidification, cause surface defects that mar appearance, and often reduce mechanical properties. In many cases, filtration cuts rejects from such causes to virtually zero. Improvements in yield to near 100% and reduced reject rates to at or near 0% are common. |
