23 10月 Aluminium Alloy Foam Ceramic Filter
Aluminium Alloy Foam Ceramic Filter was originally developed for the production of forged aluminum alloys, which are used in strict product applications.
Aluminum cans and lid materials, aluminum foil, aircraft extrusion materials, memory disks, forging materials and metal wires require extremely high cleanliness.
The first application in the foundry industry was high-quality aluminum castings for aerospace applications.
Since then, it has expanded into commercial casting and automotive applications.
Aluminium Alloy Foam Ceramic Filter has several key advantages to improve the quality of high-quality aluminum castings.
Improved mechanical properties.
Reduce signs of dye penetration.
Reduce non-metal X-ray evidence.
Improve processing performance.
Non-metals are used as nucleation sites to form hydrogen pores.
Therefore, the decrease in inclusion content will also be accompanied by a decrease in porosity caused by gas.
The filter cannot exclude hydrogen.
It only reduces the tendency to form pores.
The main benefit that may be gained by using Foam Ceramic Filter is to greatly reduce rework.
Elimination of defects in surface or subsurface properties can add considerable cost to the price of the casting, provided that these defects do not occur in critical areas.
In addition, if mixing or other finishing techniques result in loss of dimensional integrity, loss of castings may occur.
Maintenance is not an effective means of competitive production of high-quality castings.
Another major advantage of Foam Ceramic Filter
Non-metals can affect the finishing characteristics of machined castings. In the presence of non-metallic inclusions, the characteristic luster and luster of processed aluminum will disappear.
Influence of Foam Ceramic Filter on the Mechanical Properties of Casting Test Rods
The test rods are made of alloy Almag (AA535) and 356-T6.
Almag is a high-magnesium alloy that can form reasonable strength without heat treatment.
However, the high magnesium content results in the formation of scale during the casting process.
Although a high level of strength is not the usual requirement for Almag 35, pressure tightness is almost always a required attribute.
Filtration effectively reduces inclusions and improves the pressure resistance of Almag 35.
The tensile strength of the filtered and unfiltered Almag 35 alloy is very different.
The use of ceramic foam filtration has increased the achievable tensile strength by approximately 20%.
By using a filter, the influence of percent elongation of aluminum alloy is significantly improved.
The improved mechanical properties of Almag 35 may allow more applications of the alloy.
Therefore, it can be reasonably concluded that Aluminium Alloy Foam Ceramic Filter is very effective in preventing non-metallic materials from entering the aluminum melt. Therefore, the use of ceramic foam filters can obtain the best mechanical performance, both in terms of level and repeatability.
