Choosing the right metal die casting material is key. It must balance strength, cost, and application needs without sacrificing quality. At Yonglihao Machinery, we’ve been specializing in die casting services since 2010. Die casting turns metals into precise parts, from car parts to everyday items.
The right material means your parts will last and work well. You might need aluminum for its lightness and conductivity, zinc for its stability, or magnesium for its strength.
Aluminum alloys 380 and 390 are commonly used in automotive applications due to their adequate corrosion resistance and other desirable properties. Zinc alloys Zamak 3 and 5 are perfect for detailed parts. Magnesium’s AZ91D alloy is lightweight and suitable for various applications requiring a high strength-to-weight ratio, such as in aviation and electronics.
Each alloy has its own specific strengths: tensile strength ranging from approximately 230 to 400 MPa, depending on the type and treatment, specific melting points, and finishes for plating. Knowing these details helps your project meet its goals and budget.
The Yonglihao Machinery team has more than a decade of experience in metal casting alloys. Whether you need aluminum’s heat conductivity or zinc’s toughness, the right choice depends on your project. This guide helps you understand the options, specs, and uses to make your choice easier.

Understanding Die Casting Process and Material Requirements
Next, let’s understand what the die casting process is. At Yonglihao Machinery, we have over 20 years of experience. We keep up with the latest in die casting processes and alloys. The process begins with making hardened steel dies to mold molten metals.
Choosing the right materials is key. It makes sure parts work well and last long in different industries.
The Fundamentals of Die Casting Technology
Die casting has standard steps but changes based on the material. Key steps include:
- Molten materials poured into high-pressure dies
- Material solidification under controlled cooling
- Ejection of finished parts after cooling cycles
Our team adjusts things like injection speed and pressure. We do this based on how the metal alloy behaves when it’s hot.
Why Material Selection Matters in Die Casting
Choosing the right material affects how well a part works and its cost. Important factors include:
- Process compatibility: Aluminum needs cold-chamber systems because it melts at high temperatures
- Structural performance: Zinc alloys are great for detailed designs because they cast well
- Cost-efficiency: Magnesium alloys are light but strong, saving on weight
Our engineers look at these factors. They aim to meet technical needs while keeping costs down.
Evolution of Die Casting Materials Since 2010
Since 2010, die casting alloys have gotten a lot better. Aluminum alloys like A380 are now 20% stronger and lighter. Zinc alloys have less porosity by 30%, thanks to better control.
New alloys have:
- Better resistance to corrosion for cars
- Improved heat stability for electronics
- Less need for extra processing
We work with R&D partners to use these new materials. This way, we make parts that meet ISO 9001 standards for cars and planes.
Our technical team uses software to predict how materials will behave. This helps us choose the best materials. Our clients have benefited from our 10+ years of experience in die casting.
Common Die Casting Material Options and Their Characteristics
At Yonglihao Machinery, we focus on choosing the right materials for every project. Here are some common die casting materials and what makes them special:
- Aluminum Die Casting Material: Alloys like A380, A360, and A390 are great for cars and industrial parts. A380 is good for engine parts because it doesn’t crack easily. A413 is perfect for medical and building parts because it doesn’t rust.
- Zinc Die Casting Material: There is a difference between zinc die casting and aluminum die casting. Zinc alloys, like Zamak 3 and Zamak 5, have excellent finishes and can make complex shapes. Zamak 5 is strong and good for everyday items.
- Magnesium Die Casting Material: Alloys like AZ91D are 33% lighter than aluminum. They’re used in planes and electronics because they’re light and don’t rust.
- Copper-Based Alloys: Bronze and brass are good for electrical and marine parts because they conduct heat well. Silicon brass is great for making detailed designs.
Our team looks at things like how well they handle heat and their cost. For example, A518 is easy to machine and is used in marine parts. Magnesium alloys help make cars lighter. We follow all the rules and try to be green.
Properties That Define Premium Die Casting Metal Alloys
Choosing the right die casting materials is key. We look at fluidity, thermal stability, and mechanical strength. At Yonglihao Machinery, we make sure components meet high standards. We check fluidity, solidification, and corrosion resistance for each project.
- Fluidity shows how well molten alloy fills molds. Alloys like A383, with more silicon, work great in detailed molds.
- Thermal properties like conductivity and expansion rate impact cycle times. A356 and A357 alloys cool fast and are strong for car parts.
- Mechanical strength must match the part’s use. B390’s high silicon content helps with wear, while A360 balances ductility and corrosion.
- Corrosion resistance is vital for marine or industrial parts. Zinc-based alloys naturally resist corrosion without extra treatments.
Material choice also depends on post-processing needs. Maraging steels (250, 350) and cobalt alloys like Stellite 6B last under harsh conditions. Our team checks each material’s ability to keep its shape and finish over cycles. We match alloy properties with manufacturing needs for top results.
How to Select the Ideal Die Casting Material for Your Project
At Yonglihao Machinery, we focus on making smart choices for your project. We look at what your project needs, like how much stress it can handle, how hot it gets, and where it will be used. This helps us pick the right material for your project.
- Mechanical strength needs (tensile/yield thresholds)
- Temperature resistance (e.g., aluminum die casting material for high-heat automotive parts)
- Corrosion resistance for marine or medical applications
- Dimensional stability for precision components
Cost Considerations in Material Selection
Looking at costs means more than just the price of the material. Zinc is good for making lots of parts because it’s cheap. But aluminum is better for things that need to be strong but light, like in planes. We think about:
- Processing energy demands
- Die wear rates affecting tooling costs
- Secondary finishing requirements
Industry-Specific Material Standards
Car parts need to meet SAE/ASTM standards, often using aluminum alloy A380. Medical tools must be safe, using zinc alloys that meet ISO 10993. For aircraft, we use magnesium alloys that meet stringent aerospace standards, such as ASTM or AMS specifications, to ensure they are strong and reliable.
Environmental Factors and Sustainability
We choose materials that are good for the planet, like aluminum and zinc. They can be recycled and still work well. We also pick magnesium for cars to make them lighter and cut down on pollution. We follow rules to use fewer harmful materials.
