The Alloys of Die Casting
The Alloys of Die Casting. Aluminum is one of the most common alloys used in die casting. Aluminum is also one of the many alloys that can undergo almost all the process in casting. Die casting is where the aluminum is mostly used. But pure aluminum casting is rarely produced because of the susceptibility of the alloy to cracking and shrinkage. This alloy is usually alloyed with silicon and copper because these two alloys can increase melt fluidity, especially silicon, and reduces ductility. Silicon can also reduce maintainability of the alloy and copper can increase the hardness. The combination of the three alloys can reduce corrosion. For better corrosion resistance, aluminum casting with lower copper should be used such as 360 and 413. Aluminum is also commonly used when it comes to electricity because of its conductivity and high temperature strength. Aluminum has many uses in today’s everyday lives from office to home to commercial uses and industrial uses.
Furthermore, Aluminum Die Casting also has high dimensional stability when doing complex shapes and thin walls. The typical applications of aluminum alloy are Alloy 380.0, A380.0, 360, 413, and 518.1. They are typically used for home equipment like lawnmower, dental equipment, street lamp housings, frying skillets, escalator parts, connecting rods, instrument cases, and marine and aircraft hardware. Alloy 518 is known to have the highest corrosion resistance but it has low fluidity compared to the other aluminum alloys. This is also usually the most expensive aluminum alloy because of the difficulty to cast.
Also, Aluminum casting usually doesn’t undergo heat treatment but instead undergo metallurgical stabilization and dimensional treatment.
Aluminum Heat Sinks are Die Casted
Aluminum Heat Sinks are Die Casted. Aluminum Heat Sinks have one important purpose, and that is to regulate heat generated by the product it is in. These heat sinks are placed in most electronics and appliances so that the heat from electrical wiring and other parts of the product are diverted from them into the heat sink, thus protecting them from overheating and malfunctioning. In other words, Aluminum Heatsinks provide a very important safety feature for these products. This means that throughout its life span, it will take on a lot of abuse and beating, which is why aluminum is ideal for the job.
Did you know that aluminum is a very tough and durable material? It has been noted that it is comparable to steel in terms of durability. But, when it comes to weight, aluminum weighs just a third of steel of the same size and shape. This makes it ideal for making heat sinks. Also, aluminum can be harvested almost anywhere in the world. This means that it is cheap and easy to acquire. To meet high demands for Aluminum Heat Sinks, the manufacturing process known as die casting is used.
Furthermore, the first step in die casting Aluminum Heatsinks is to liquefy the aluminum bars that are going to be used. Once in their liquid state, they will then be injected into casting molds. These castings give the liquid its new shape. Then, pressure of up to 35,000 pounds per square inch/PSI is applied on the castings. This will let the liquid set in every part of the die cast mold. It will then be set aside to cool and harden. Once opened, the product only requires a few finishing touches and its done.

Why are Aluminum Die Casting Parts better than Zinc Diecast Parts
Thank you for reading our newsletter. Please feel free to make a comment below about this article. You can also visit our facebook page to see other topics we are sharing with our customers. If you have suggestions for future articles, please send them to us.
Here is a comparison of aluminum parts and zinc parts:
Die Casting Tooling
A die casting mold made for an aluminum part runs in a cold chamber die casting machine. The die casting alloys aluminum and zinc both run in a cold chamber die casting machine. So if the die casting mold is made for aluminum, it will produce parts in zinc or aluminum. A zinc hot chamber die will not make parts in aluminum.
Die Casting Part Weight
Although an aluminum die casting mold will make parts in zinc or aluminum, the cost of the zinc parts will be higher. By volume, zinc materials weigh about twice as much as aluminum alloys. The costs per pound of the two die casting alloys are almost equal, so the cost for zinc parts is significantly higher than the cost for aluminum parts.
Electrical Conductivity
Aluminum is the third most electrically conductive metal after gold and copper. Therefore, aluminum is the better choice for EMI/RF shielding and for electrical grounding. Zinc rates far below aluminum in electrical conductivity.
Thermal Conductivity
Most electrical heat sinks are produced in aluminum alloy because it is superior to zinc alloy in thermal conductivity.
Recyclability
Aluminum is the most recycled metal in the world. All aluminum die casting alloys are made from recycled aluminum products.

Why are Aluminum Die Casting Parts better than Zinc Diecast Parts
Porosity–What is it?
What is Die Casting Porosity? In order for you to know what die casting porosity is, you need to know the basics. Die casting is a process wherein a particular amount of molten metal is put inside a container, then it is applied with great force so as to force it into a die cast mold. After this, the metal is left to cool down and harden then it is removed. The same process is repeated over again. Die casting companies use metals which are non-ferrous, or do not contain Iron, as this is the highest factor for oxidation and rusting. Several examples of non-ferrous metals include zinc, aluminum, lead, magnesium, tin and copper.
It is a kind of factory defect in which die casts contain small pockets of void space and air within the metal or plastic, causing it to become porous. Eventually, these air pockets cause the die casted material to become brittle and weak. Usually, die casting porosity is an unwanted result and is considered as a substandard product.
Basically, it is caused by poor handling and casting process. There might have been small cracks and crevices in the machine where the air could come in. The mixing process of the metal may have been poor, therefore creates bubbles inside the metal. One needs to check up the machine used for die casting regularly to prevent this kind of problem. It is also recommended to use vacuum devices to suck out the air inside the molten substance to reduce the incidence of die casting porosity.

Aluminum Auto Parts
Die Casted Aluminum Auto Parts. Aluminum Auto Parts are becoming very popular among car manufacturers all over the world. Using aluminum has proven to be better compared to using other types of metal such as steel because of its properties. First of all, aluminum as just as strong and durable, if not even stronger and more durable, than steel, secondly aluminum weighs significantly lower than steel of the same size. In fact, Aluminum Car Parts weighs only a third of the same steel parts, making it easier to handle and adding less weight to the car. Aluminum can be mined almost everywhere in the world making it a cheap metal as well. Lastly, Aluminum Auto Parts can be die casted to meet demands for bulk orders.
The manufacturing process known as die casting aluminum is perfect for making small sized parts as well as medium sized parts. The finish of the product is amazing as the dimensions are accurate and the surface finish great. In other words, the resulting parts are high standard and consistent each time. This is because Aluminum Auto Parts are made first by liquefying the aluminum. The resulting liquid metal is then injected into molds, its crevices will give the liquid its new shape. Applying pressure of around 1,500 PSI to 30,000 PSI, the liquid is forced into every nook and cranny of the mold. This increases the accuracy of the product’s dimensions. The molds are then set aside to cool for a while and once they are opened, the Aluminum Auto Parts are finished.
