Foam Ceramic Filter Nordural has many advantages such as good chemical stability, high specific strength, high temperature resistance, thermal shock resistance, and large specific surface area. It is widely used in the aluminum melting and casting metallurgy industry.
In metallurgy, the use of ceramic foam filter plates to remove foreign contaminants in the lead melt, such as slag and inclusions, is one of the most effective melt cleaning methods.
Studies have shown that in addition to slag, it can also reduce the hydrogen content in molten aluminum.
Because of its good slag removal effect, simple operation, easy adaptation to other parts, and low cost, it has become a conventional cleaning method in the aluminum processing industry.
As the requirements for the quality of aluminum products are getting higher and higher, the requirements for the filter plate are also getting higher and higher.
When purchasing filter materials at Nordural, carefully evaluate the effective specific surface area or porosity calculation of the foam.
Observe the uniformity of the mesh on the surface of the filter plate, and then observe the uniformity of the mesh on the cross section of the filter plate.
If possible, the drainage method can be used to calculate the porosity.
The three-dimensional lattice is uniform and the porosity is large. It is a kind of foam ceramic filter plate with excellent performance.

All ceramic foam filters are characterized by a grid matrix. Spherical holes of the same size and volume are connected to each other, forming “windows” through their walls.
Because of its structure has a rather tortuous path, the pores can pass through the metal and retain slag and other types of contaminants.
In the end, this ppa-based filter with a specific structure has shown excellent efficiency when filtering metals in the context of filters with different structures used in the foundry industry.
Among various types of metal oxide ceramics, alumina has the best high temperature stability.
Most suitable for ceramic coatings and high temperature refractory products.
The thermal conductivity of alumina is the lowest among ordinary ceramic materials, and its thermal expansion coefficient is relatively close to that of metal materials.
In Nordural, 600 employees work around the clock, using electricity from Iceland’s renewable resources to process pure aluminum from alumina. Our products, pure aluminum and various aluminum alloys, are shipped to international customers, turning green energy from falling water and geothermal into one of Iceland’s most valuable export products.
Noroural has implemented green accounting for its operations, which is a comprehensive record of all materials entering and leaving the aluminum plant. Our goal is to limit the impact on the environment.
In 2020, we produced 312.629 tons of aluminum and aluminum alloys. Electricity consumption accounts for approximately 25% of Iceland’s total electricity generation. The total number of employees is 581.
