What is the most common aluminum alloy for die cast?

May 13, 2026

A380 is the most commonly used aluminum alloy in die casting. Experts favor this alloy because it is easy to cast, has high strength, and is cost-effective. MORELUX utilizes new technologies and expertise to produce high-quality aluminum die castings for numerous industries.

Key Takeaways

  • A380 is the most commonly used aluminum alloy in die casting because of its high strength, ease of use, and affordability.
  • This alloy has excellent fluidity, allowing for rapid mold filling and the production of fine parts with fewer errors.
  • Choosing the right aluminum alloy, such as A380, can improve product quality and help many industries save costs.

Why Alloy 380 for Aluminum Die Casting

Key Properties of Alloy 380

Alloy 380 is the most commonly used aluminum alloy in die casting. Many manufacturers choose this alloy because of its high strength and ease of machining. The table below lists the main mechanical properties of alloy 380:

PropertyValue
HardnessHB 60
Tensile Strength≥ 320 MPa
Elongation≥ 3.5%
Yield Strength≥ 160 MPa
Tensile Strength (ksi)47 ksi
Yield Strength (ksi)23 ksi

These data demonstrate that Alloy 380 is tough, durable, and has a long service life. It possesses a certain degree of bending toughness and is not easily broken, making it an ideal choice for many parts.

Alloy 380 is also well-suited for manufacturing die-cast parts. Due to its ease of casting, manufacturers can produce parts with finely shaped components, reducing errors. Alloy 380 is resistant to rust, so parts maintain a long service life even in harsh environments. Many companies use this alloy for die casting because it meets high standards.

Advantages in High-Pressure Die Casting

High-pressure die casting requires an alloy that can quickly fill the mold and produce intricate parts. Alloy 380 is ideally suited for this purpose because it offers numerous advantages:

AdvantageDescription
High FluidityFills molds all the way, even with hard shapes.
Good Thermal ConductivityCools down fast, so production is quicker.
Excellent Strength-to-Weight RatioMakes parts that are strong but not heavy.
Low ShrinkageLess chance of cracks or bending.
Corrosion ResistanceWorks well in wet or rough places.
Surface FinishMakes smooth parts with sharp details, so less work is needed after.

Alloy 380 also helps save costs when mass-producing parts. It fills molds quickly, resulting in shorter production times for each part. Production costs are also lower because less post-production repair work is required.

MORELUX uses new technologies and expertise to produce high-quality aluminum die-castings. Their team selects rust-resistant alloys like A380. This helps produce robust and durable parts for numerous industries. With extensive experience, they ensure that every project meets high standards of quality and strength requirements.

Aluminum Die Casting Alloys Compared

Alloy 380 vs. 383, 413, and 360

Many companies use different aluminum die-casting alloys. Each alloy helps to meet specific needs. Alloy 380 is popular due to its high strength, ease of casting, and lower cost. Other alloys, such as 360, 383, and 413, also have their own unique properties.

Choosing the Right Aluminum Alloy for Die Cast

Picking the right aluminum alloy depends on a few things:

  1. Decide what you want, like strength or rust resistance.
  2. See if the part is thin or has tricky shapes. These need alloys that flow well.
  3. Compare prices and how many parts you need.
  4. Make sure the process fits the alloy, like heat treatment or leak tests.

Some alloys, like A380, can be recycled and save energy. Industry rules help pick the best alloy so parts last longer and work well. For gravity casting, A356 is used because it bends easily and resists rust. This makes it great for planes and cars.

Tip: Choosing the right aluminum alloy helps stop problems and makes strong parts you can trust.
