How to Choose the Right Aluminum Alloy for Diecasting
Structures are surfacing more on the lands to bring people closer to each other with the congested buildings. There is undoubtedly a need for stronger components in the infrastructure to hold the pressure of the increasing population. We know the demand for job opportunities in a region is also on the rise as the number of people increases with time; so, we want the right materials and the best system to provide us with unlimited options. Lightweight structural components are required more these days to make construction easier, but the stability and strength are not to be affected by these items.
Aluminum castings are used often these days, and these have been in the market for quite some time now. Withstanding the highest operating temperatures would take the most durable material, and the cast aluminum would be a perfect option. Although companies have been using the product for various purposes, many end up having the desired properties. Let us look at how you must choose the best aluminum alloy for your diecasting projects.
What to Consider
When you are still confused about the right product for your structure, you must look for the properties of the aluminum alloys that would be of great application in your project. The three most important factors to look for are:
- Chemical composition
- Mechanical and physical properties
Aluminum alloys may contain several components, including iron, copper, silicon, zinc, nickel, titanium, manganese, magnesium, and tin. All these would have different properties, and you must read through the details to pick the one that meets your requirements. Technical data about mechanical properties and chemical compositions can be asked for at the company you decide to purchase the product from or simply search for it online. The best alloy can be chosen only when you know every aspect that determines the quality of a product, which might have recycled or new elements to provide for your needs.
Alloys You Can Use
Several types of aluminum alloys are available in the market to be used for diecasting, but the highly recommended ones include:
This aluminum alloy is the most cost-effective and common type used for diecasting, and it stands as the best option by combining the factors of cost and utility. 380 aluminum also provides the right characteristics for an above-average machining experience.
360 aluminum is the next best option on this list because it comes with superior strength, high corrosion resistance, and fairly good ductility. However, this one would be slightly harder to cast.
This is a modification of 380 aluminum. It comes with better die filling properties but has lower toughness than the other options.
While all the other alloys are used for normal projects, 390 aluminum is best for special applications that require better strength, wear-resistance, and fluidity.
413 is another option we usually use for higher pressure projects since it provides maximum fluidity and tightness.
