Common Materials Used in Die Casting for Automotive Industry
Many metals can be suitable die casting materials, especially non-ferrous metals. However, the most common materials for die casting in the automotive industry are zinc, aluminum, and magnesium. These metals have their unique advantages and ideal applications. Let’s take a look at them.Get more news about Desktop Cnc Machine Parts,you can vist our website!
Zinc Die Casting

Zinc die casting makes up almost 28% of automotive die casting components. Although it was commonly used in the industrial sector due to its high impact strength and ductility, it is now widely popular in the automotive sector. Being castable in hot chamber die casting machines, this process gives an accuracy of almost 100%. As a result, it produces parts with smooth finishes and eliminates the need for further processing.This die-casting metal is prominent for products like door lock housing, retractor gears, pulleys in seat belts, and many more. Besides, it is ideal for creating automotive parts with quality aesthetics requirements, embossing, or strict tolerances.
Advantages of Zinc Die Casting
Some of the advantages of zinc die casting include the following:Increased Flexibility. Zinc beats other casting materials when it comes to fluidity. While aluminum is more lightweight than zing, it can help create intricate parts with complex shapes and thinner walls.
High Resistance to Corrosion. Zinc reacts very minimally upon exposure to the atmosphere. Therefore, parts made from this metal are usually durable. These die-cast parts often stay for extended periods without needing constant maintenance.
Excellent Thermal and Electrical Conductivity. We are in the era of advanced vehicles and smarter automobiles. Therefore, it is important to make their components with metals that can withstand those needs. Zinc conducts heat and electricity effectively, making it the ideal choice in this case.
Sustainability and Eco-friendliness. Zinc is environmentally friendly and is easily recycled into new products. Therefore, it is a great choice for automotive die casting to prevent excessive waste and the release of harmful substances into the environment.
Dimensional Stability. Zinc also beats other die-cast metals in terms of dimensional stability. Auto parts casting with zinc gives products with superior finish and aesthetic appeal.Aluminum is another popular metal used in manufacturing automobile parts. It is lightweight and has excellent dimensional stability, making them top choices for thin-walled machine parts. Generally, low-density aluminum is more extensively used in the automotive industry. Automotive castings from this metal have higher strength even at high temperatures.The aluminum die casting process can employ a steel mold to produce thousands of castings in one session. It is ideal for making parts such as engine brackets, gearbox cases, valve bodies, hydraulic cylinders, etc.
