When considering aluminum investment castings you need to be aware of the pros and cons, the advantages and possible drawbacks. You must have heard if you are part of any relevant industry, about the benefits of using aluminum castings for today’s industrial needs. There are many uses for aluminum parts in the industry of 21st century – some demanding pure aluminum, while others involve the use of other metals to mix and form different types of alloys.

The Advantages of Aluminum Investment Castings

There are many, many benefits that would benefit any industry which adapts aluminum investment castings for their needs of metal parts duplication or manufacture. The main benefits would be:

Corrosion resistance – aluminum investment castings uses aluminum because it does not corrode like its counterparts such as iron, copper and the like. Though it is not as conducive the copper, aluminum makes up on that by its anti-corrosive properties.

Light weight – since aluminum is extremely light weight, this metal could be used for applications requiring large, intricately-designed parts, yet allow the casting to be easily managed. The lightweight applications are especially important in industries such as the aeronautics, rocket science and ships.

Malleability – aluminum is also extremely malleable which makes it a great choice for these parts using aluminum investment castings which needs everything to go into it. You could easily manufacture parts that are as thin as 0.4 mm – which is really thin by any standards.

The Cons of Aluminum Investment Castings

As with any positive thing, there has to be some downside. In this case the most important disadvantage is that aluminum investment castings require a method which can initially appear to be more expensive. However, a comparison of post-production handling cost will quickly reveal that the initial cost is deceptive.

The fact is that aluminum investment castings come out requiring little to no follow-up such as: polishing, milling, drilling, turning or grinding of the casting after it is taken out from the mold. This immediately translates into a savings of time as well as money. Hence, in spite of it appearing at first glance to be expensive, it is still the most cost-effective type of casting available.
