Aluminium Castings Advantages

With the continuous development of society, people's living needs are also getting higher and higher, and the demand for Aluminum Casting process is also increasing. When we use and use aluminum casting process, do we understand the advantages of aluminum casting produced by aluminum casting?

The advantages are as follows:

1, the product quality is good: the casting dimension accuracy is high, generally equivalent to 6~7 grade, its up to 4 grade; Good surface finish, generally equivalent to 5-8 grade: high strength and hardness, the strength is generally higher than Sand Casting 25-30%, but the elongation is reduced by about 70%; Stable size, good interchangeability; Die - cast aluminum thin - walled complex castings. For example, the current minimum wall thickness of zinc alloy die casting aluminum parts can reach 0.3mm; Aluminum alloy casting up to 0.5mm; The minimum cast aperture is 0.7mm; The minimum pitch is 0.75mm.

2, high production efficiency and high machine productivity, such as domestic JⅢ3 horizontal cold air die casting machine can die casting aluminum 600~700 times in an average of eight hours, small hot chamber die casting machine can die casting aluminum 3000~7000 times in an average of eight hours; Die casting aluminum mold has a long life, a set of die casting aluminum mold, die casting aluminum bell alloy, life can reach hundreds of thousands of times, even millions of times; easy

Realize mechanization and automation.

3, excellent economic effect due to the precise size of die-casting aluminum, surface gloss and other advantages. Generally no longer for mechanical processing and direct use, or processing volume is very small, so it not only improves the metal utilization rate, but also reduces a lot of processing equipment and working hours, casting price is cheap; Aluminum can be combined with other metal or non-metal materials. It saves both assembly time and metal.

4, aluminum castings are being used in the process of its advantage in (explanation: can overwhelm the other side of the favorable situation) is quite significant, the use of the product domain, occupies a large part of the auto industry, especially now the auto industry especially pay attention to the light of the properties of aluminum castings can get more extensive application in automobile industry, The density of aluminum castings is actually lighter than that of iron castings and steel castings, and the strength of aluminum castings is relatively large in the process of use.

5. The weight of aluminum casting is relatively light, but its products can bear relatively high weight. In the process of design, the structural weight of the casting can be effectively reduced, so such equipment is widely used in industry, transportation machinery and power machinery.

6, in the chemical industry, the aluminum (Al) castings are widely used in the certain degree, main is to use when making use of the thermal conductivity, aluminum alloy and pure aluminum in the aluminum castings made after can be used in the chemical production of heat exchange device (type: hybrid power machinery and surface type and has good heat conduction performance of the parts. Non-ferrous metal casting accounts for a large share of the use of non-ferrous metal materials (sometimes nearly half), forming a large and complex series of cast alloys. Non-ferrous alloy casting, in the non-ferrous metal alloy, copper alloy, aluminum alloy, magnesium alloy, zinc alloy and so on can be used for casting.

7. The density of aluminum (Al) castings is smaller than that of cast iron and steel, and the specific strength is higher. Non-ferrous metal casting non-ferrous metal smelters often supply metal ingot with certain chemical composition for the subsequent process of preparation of various alloys; Smelters and processing plants are also often separate. Therefore, under the condition of accepting the same load, the selection of aluminum alloy castings can reduce the component of the layout, so in the aviation industry and power machinery and transport machinery production, aluminum castings are widely used.

8. Aluminum castings have outstanding casting functions. Because the melting point is low, it can widely choose metal mold and pressure casting casting methods, in order to improve the content quality of castings, scale accuracy and appearance of smoothness and production power.

9. Because of the large latent heat of condensation on aluminum castings, under the same component conditions, the condensation process of liquid aluminum is continuously much longer than that of cast steel and cast iron, and the discharge fluidity is excellent, which is conducive to the casting of thin wall and disorderly layout of the castings.
