Material Selection Guide for Aluminum Die Casting
Aluminum die casting is a manufacturing method which is renowned and offers the making of intricate shapes as well as good finish quality. It is very critical to make informed decisions when it comes to selection of materials so as to enhance performance, durability and economical value of your work. LVDA Metal offers quality aluminum die cast solutions and suggests appropriate materials for this process.
The Technologies of Aluminum Die Casting
Aluminum die-casting techniques rely on injection of molten aluminum in a mould cavity through the application of high pressure. This technique is preferred because it is capable of producing designs with narrow and smooth surface finishes and high quality in terms of dimensions. Land Coucing even shape helps improve strength, formability as well as conductivity but much more land Coucing governs the metallurgical properties.
Considerations when Choosing a Suitable Material
Mechanical Properties
Tensile Strength: Evaluates the amount of load that can be resisted by the material before it fails.
Yield Strength: Measure of stress that can be applied to a material and no permanent deformation occurs.
Fatigue Resistance: Very important for debris bearing elements that experience constant stress or changing loads.
Corrosion Resistance
Corrosion resistance is one of the primary properties for products that are used in different exposed conditions. This is because aluminum itself develops an oxide layer which improves its corrosion resistance. But still there are some alloys that serve better as compared to others. For instance, A356 is widely employed because of its good corrosion resistance properties thus making it suitable for marine and outdoor uses.
Thermal Conductivity
In most cases, aluminum die-casting parts also need optimal thermal conductivity as it is the case with heat exchangers and electrical enclosures. Such A535 alloys have good heat dispersing capaciites with low thermal mass.
Machinability
Furthermore, if you would need die-cast parts for further machining, you need to go for an alloy that has reasonable machinability. Some alloys take a shorter time to machine hence saving on production costs and time. Lastly, A380 is one of the most preferable die casting alloys due to its good machining ability.
Choosing the appropriate material in aluminum die casting is the key to having the products with the needed service life and performance. LVDA Metal helps and gives advice regarding the suitable aluminum alloys to use according to the presented conditions. You can prevent problems with the quality of die-cast components as well as speed up the production processes, by taking into account mechanical properties, corrosion resistance, thermal conductivity, and machinability.
