Aluminium and Magnesium Properties That Make Them Perfect for Casting

13 March 2020

Casting is the process of pouring liquid metal into moulds to create parts and other items. Manufacturers use special machines to accomplish this task. Also, they must use the ideal materials to ensure quality results. Two of the materials that a highly suitable for this process today are aluminium and magnesium. Each type of metal brings its unique characteristics to casting products and parts.

Reasons That Magnesium Is Used in Casting

Magnesium is the lightest weight of the metals. In its natural state, it is a pale silver metal. Also, it is among the top ten most abundant elements not only on earth but in the universe. It can be combined with zinc, aluminium, manganese, copper and other metals to create the ideal alloy for your specific project since magnesium alloys have a complex plastic deformation. As a result, magnesium alloys are in many cast products including automobile parts, airline parts, cameras and their lenses and many other products. Also, this metal provides high thermal and electrical conductivity, which makes it durable in high-temperature applications. On top of all this, it can be used to shield rooms from radio frequency and electromagnetic frequency interference. In comparison to other casting materials, it is a cost-effective choice.

Why Aluminium Is Suitable for Casting

1. Flexibility in Design

Like the magnesium, aluminium can be mixed with other metals when necessary to create alloys. Aluminium and its alloys can be cast in numerous designs. This gives you great flexibility with your options and preferences. Also, this metal can be cast to make small, intricate pieces as well as medium to large complex ones.

2. Requires Less Machining

Machining is a pricey process and when you can avoid an excessive amount of it, it will save you on the overall cost of your parts or other casted items. Aluminium requires less machining after casting than other metals require.

3. Provides High Strength

Aluminium is strong and durable once it cools from the casting process. It will provide a high return on your investment since it will endure numerous types of situations and uses.

4. A Cost-Effective Casting Material

Similar to magnesium, it is an affordable material to select for your casting needs. A benefit such as this is extremely important when you need numerous parts or items casted or are on a limited budget.

5. Aesthetically Pleasing Finish

Aluminium and its alloys also provide an eye-catching finish to components and items.

Both Aluminium and Magnesium Are Recyclable

Another reason that both these metals are ideal for casting today is that they are recyclable. They along with their alloys can be turned into other products rather than just decaying in landfills.
