Aluminium 7075 Ceramic Foam Filters For Casting is basically divided into 6 pore sizes: 10 PPI, 15 PPI, 20 PPI, 25 PPI, 30 PPI y 40 PPI. Cuanto mayor es el número, menor es la abertura. Sin embargo, en la práctica, los cuatro tipos (10 PPI, 20 PPI, 30 PPI y 40 PPI) satisfacen las necesidades de los clientes.

Selección de la apertura
1. El moldeado: 10～25 ppi
2. Colada semicontinua: 30～60 ppi
3. Aluminio o chapa de alta calidad: 50～60 ppp
4. Colada continua y laminación: 50～60 p

Ceramic Foam Filters For Casting can not only effectively eliminate the larger oxidized inclusions in the molten aluminum, but also filter out the fine inclusions of a few microns that cannot be removed by the traditional process.
Because the hydrogen atoms, sodium, potassium and other harmful ions in the aluminum liquid are often adsorbed on the inclusions, the inclusions can become the core of the formation of bubbles, so while filtering the inclusions, these harmful elements in the aluminum liquid can also be reduced.
The ceramic foam filter plate filters out many small inclusions, thereby reducing the required effective crystal nucleus for the solidification of molten aluminum, thereby promoting the growth of molten aluminum nucleation under relatively large supercooling conditions, which can be refined and structured.

7075 aluminum alloy is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available. The 7075 aluminum alloy has a compact structure and strong corrosion resistance, which is best for aviation and marine plates. General corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, and the tool wear resistance is enhanced.

General corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more distinctive. Zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the alloy’s heat treatment effect far better than aluminum-zinc binary alloys. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and spalling corrosion will decrease accordingly. After heat treatment, very high strength characteristics can be achieved.

Filtro de espuma cerámica. Tamaño de poro (PPI): 10/20/30/40/50/60

30ppi 40ppi Filtro de fundición es el filtro de espuma cerámica más utilizado en la industria de la fundición de aluminio.
En la fundición de aluminio convencional se suelen utilizar placas filtrantes cerámicas de entre 10 y 40 ppi.
En el sector de la aviación y en los materiales de aluminio de alta calidad se suelen utilizar placas filtrantes cerámicas de entre 30 y 60 ppi.
