Aluminum Die Casting vs stainless steel casting: Choosing the right one for your cast

It is obvious to get confused between the terms. Aluminum die casting and stainless steel casting. As these two terms have a minor difference, and very few people are aware of the difference. 

Aluminum does not have much weight and is known as a lightweight alloy. The aluminum possesses high stability in almost all the segments, including complex shapes and unique designs, and it also has thin wall sections. So, this kind of die casting produces aluminum-based products. 

On the other hand, stainless steel casting, also known as stainless steel investment casting, makes complicated products. 

It is essential to decide which kind of casting is best for the product you are targeting to manufacture. To select the type of casting, you must first make a list of raw materials, check their melting point. Then you must check whether it needs to be made of steel and should be hard or should be made of various alloys, having a different composition, and should be super thin. 

Based on these criteria, you can select and finalize the casting. To clear all your confusion and misconceptions, here we are explaining the fundamental difference between aluminum die casting and stainless steel casting

Before getting started with the difference, let us first explain to you and tell you some essential points that you must know before getting your products to die cast by aluminum. 

1. It would be best if you wisely chose the proper alloy of aluminum before getting it die-casted. All the alloys have various components, and every product made by aluminum die casting has multiple chemical elements. 

So, one must indeed check the alloy properly and must cross-verify the components as well. For example, some may have a combination of zinc, copper, iron, while some other aluminum alloys might have varieties such as magnesium, nickel, cobalt, and many more. 

2. There are many types of alloys available in the market, and thus it becomes challenging to select the alloy that best suits your requirement. 

To tackle this issue, you can ask the seller and discuss all your requirements with them. In this case, the seller would be able to help you to a great extent. 

So, before deciding the alloy you are planning to use for your project or your requirement, you must consider these two points. 

This was the basis of aluminum die casting. Let’s quickly jump to the difference between both types of casting. 

Aluminium Die Casting

  •  It can withstand high operating temperatures. 
  • Aluminum die casting is not as strong or powerful when compared with stainless steel casting. 
  • Products like aluminum cooking utensils, antacids, and antiperspirants can be remolded to make them more accessible and safe. 
  • The aluminum die-casting process involves various processes, including machines used for die casting, furnaces, and desired combination of aluminum alloy. 
  • It is very light in weight when compared with stainless steel casting. 
  • Generally the aluminum die casting tooling is more expensive than stainless steel casting tooling. . 

Stainless Steel Casting

  •  It is popularly known for having a high level of tolerance. 
  • Stainless steel casting is the most potent type of casting and can make almost all kinds of complex steel products. 
  • All the products made up of steel or even have slight components as steel can be made by this kind of casting.
  • The process of stainless steel casting involves many things. Some of them are creating an ideal wax model, layering such that the shell’s borders become strong, and building the image with plaster. 
  • It is cumbersome in weight. 
  • When compared with other kinds of casting, it is the most economical kind of casting. 

The Bottom Line

There was a significant difference between the two types of casting. However, we would like to suggest you cross-verify at least ten times before deciding which casting method you want to use. And you must make a list of all the requirements and points that you are looking for, and based on those, you can make a better decision of the type of casting. As there are many types of casting, including stainless steel casting and aluminum die casting. 

Concluding the points of both the types of casting in simpler words:-

 If you want to make anything with a rough surface or is complicated, you must undoubtedly go with stainless steel casting. On the contrary, if you are looking to produce products with different combinations or compositions of alloys, you must think about aluminum die casting. 

Also, if you have particular requirements that don’t match with any of the given two types of casting, you can ask the supplier to help you out, and you can consider the other casting methods as well. The different methods include sand casting, titanium casting, magnesium casting, and many more. We hope that by now, you would have understood how difficult it could be to choose the casting that best suits your end product.
