How many mesh of red sand is needed for sand casting crafts

In the pure aluminum by adding some metal or non-metal elements melted aluminum alloy is a new type of alloy materials, due to its small specific gravity, high specific strength, has a good overall performance, so it is widely used in the aviation industry, automobile manufacturing, power instrumentation, tools and civil appliances manufacturing and other aspects. With the development of national economy and the advancement of economic integration process, its production and consumption have exceeded the trend of iron and steel. Strengthen the research on the performance of aluminum alloy materials to ensure that aluminum alloy castings have excellent quality, not only is each of our scientific and technological workers are obliged to responsibility, but also with our daily life is closely related to the top priority. This article combines the author of aluminum alloy castings production experience to talk about aluminum alloy casting porosity and prevention.
