Ceramic Foam Filter Aluminium Korba, Cast Aluminum Alloy

Ceramic Foam Filter Aluminium Korba has a three-dimensional structure, is not wetted by molten Aluminium, heat resistant impact, can remove more than 12 micron of non-metallic impurities in molten Aluminium smelting and casting factory.

Ceramic Foam Filter Aluminium Korba can effectively intercept the clamps and sundries in liquid metal to improve casting quality and yield. Studying the mechanism of purifying liquid metal can provide theoretical basis for the perfection and application of the filter.

Molten metal, especially molten aluminum, often contains solid substances that affect the quality of the casting. After the molten metal solidifies, this solid material appears as an impurity in the casting, resulting in reduced ductility and surface gloss.

Cast Aluminium alloy can be used to directly obtain the parts of aluminum alloy by metal casting forming process, the alloy element content of aluminum alloy casting is generally more than the corresponding deformation of aluminum alloy content.

The aluminum alloy used for the required parts is obtained directly by casting process.

It is required to have ideal casting properties: good fluidity, small shrinkage, hot crack and cold crack tendency, small segregation and suction.

The element content of cast aluminum alloy is generally higher than that of corresponding deformed aluminum alloy, and most alloys are close to eutectic.

From 1905 to 1925, the European and American countries carried out the study of industrial aluminum alloy on the basis of the study of aluminum phase diagram.

The aluminum-nickel alloy was studied earlier, but its casting performance was not good, so nickel could not become the main strengthening element.

Subsequently, the addition of copper, magnesium, manganese, silicon and other elements in aluminum was studied, and the relatively ideal properties were obtained. Therefore, some binary and multiple cast aluminum alloys were developed, among which the famous si-Aluminum-Ming alloy was used in industry around 1920.

Modern cast aluminum alloy can be divided into 4 series according to the main elements added

Aluminum-silicon, aluminum-copper, aluminum-magnesium and aluminum-zinc series

For these 4 series, each country has the corresponding alloy and alloy brand mark.

China uses ZL+3 digit marking method, the first digit represents the alloy system, wherein

1 represents the aluminum-silicon alloy system

2 represents aluminum copper alloy system

3 represents the aluminum-magnesium alloy system

4 represents the Al-Zn alloy system

Several typical cast aluminum alloys in China are shown in the table. According to the use characteristics of the alloys, they can be divided into: heat resistant cast aluminum alloy, gas tight cast aluminum alloy, corrosion resistant cast aluminum alloy and weldable cast aluminum alloy.
