Aluminum alloy casting is a kind of component casting with aluminum as the main metal element, it also contains other metal elements. Aluminum alloy die casting manufacturers are engaged in the production and processing of alloy castings, and have a good understanding of the solidification characteristics of castings.
The strength of aluminum alloy casting is higher than that of pure aluminum. According to the introduction of aluminum alloy die casting plant, there is usually one eutectic composition in the fusion of two kinds of incomplete solid solution metals, and its freezing point is lower than any other composition. In the aluminum alloy containing silicon, eutectic occurs when the silicon content reaches 11.7%. The melting point of the alloy is 100 ℃ lower than that of aluminum and 850 ℃ higher than that of silicon.
In addition to the mechanical mixing of two phases, the eutectic Al Si alloy has a lower melting point and a longer service life than the alloy with a higher melting point. In the treatment of this kind of alloy, aluminum alloy die-casting manufacturers should pay attention to increase the solidification temperature gradient, so that the transition bonding area is correspondingly reduced, and the application of high-pressure jet in the final stage is conducive to die-casting shrinkage.
The above is the detailed introduction of solidification point of Shandong Aluminum alloy die casting. For more information, please click http://www.jnhjgs.cn
