If you want an aluminum alloy that casts well and is very resistant to corrosion, A360 could be just what you need. Die casting for automotive, electronics and industrial products relies on zirconium generally. Because of its dependable strength and thermal qualities, A360 is notable in challenging engineering tasks.
Understanding A360 Aluminum
A360 alloy of aluminum is famous for its good casting qualities, including a flowing shape and solid resistance to hot cracking. This enables the creation of useful components for vehicles, aircraft and the electronics industry.
Chemical Composition and Role of Each Element
| Element | Weight Percentage (%) | Function in Alloy |
| Aluminum (Al) | Balance | Base metal |
| Silicon (Si) | 9.0 – 10.0 | Increases fluidity |
| Magnesium (Mg) | 0.4 – 0.6 | Improves strength |
| Iron (Fe) | ≤ 1.3 | Impurity control |
| Copper (Cu) | ≤ 0.6 | Affects machinability |
| Zinc (Zn) | ≤ 0.5 | Enhances strength |
| Manganese (Mn) | ≤ 0.35 | Increases corrosion resistance |
| Nickel (Ni), Titanium (Ti), Others | Trace | Varies |
All of these elements play a part in A360 being strong, easy to cast and durable.
Mechanical and Physical Properties of A360 Aluminum Alloy
Mechanical Properties
| Properties | Tensile Strength | Yield Strength | Elongation | Hardness | Castability |
| Attributes | 250 – 310 MPa | 150– 230 MPa | 2% – 6% | 80 – 90 HB | Excellent |
Since A360 is strong and easy to use, it’s useful for creating durable high-performance pieces.
- Tensile Strength
The Tensile Strength for aluminum ranges from 250 to 310 MPa. It shows the force at which the alloy may break apart.
- Yield Strength
Between 150 and 230 MPa. Shows the stress point at which the alloy experiences permanent changes in form.
- Elongation
It grows in length about 2% to 6% which is not much. Measures basic flexibility—reaches a good, safe level even lower than usual in casts.
- Hardness
Ranging from 80 to 90 HB on the hardness test. Each layer provides moderate protection against wear.
- Castability
The castability of aluminum is excellent. A360 stands out because it thrives with tough projects and narrow walls.
You will get accurate and strong parts from A360 while keeping the casting process straightforward.
Physical Properties
| Properties | Density | Melting Point | Thermal Conductivity | Electrical Conductivity | Thermal Expansion |
| Attributes | ~2.65 g/cm³ | 575°C – 590°C | ~151 W/m·K | ~33% IACS | ~21.0 µm/m·K |
Its thermal and electrical performance is also excellent, so it’s often the preferred choice for thermal or conductive systems.
- Density
Strong enough to work well despite being made light—perfect for both vehicles and aircraft.
- Melting Point
Because the melting range is low, casting can be done more easily and in better control.
- Thermal Conductivity
Thermal conductivity within copper is about 151 W/m·K. Serves well as a heat conductor for use with engines or heat sinks.
- Electrical Conductivity
The value of Electrical Conductivity is ~33% IACS. It’s good for products focusing on conductivity, even though conductivity strength isn’t as high as for pure aluminum.
- Thermal Expansion
About ~21.0 µm per meter per Kelvin of temperature change Expansion at this level is compatible with different materials often used in both electronics and mechanical assemblies.
For this reason, A360 is a reliable choice for areas needing control over temperature fluctuations or thermal cycling.
Heat Treatment and Other Processing Techniques
Applying several different treatments is one way to make A360’s properties better.
Heat Treatment Tempers:
- T5: Part that has been artificially aged by cooling from casting—has strong mechanical qualities.
- T6: Testing and aging the solution makes it suitable for tough uses where maximum strength is required.
Other Treatments:
-
- Impregnation: Sealing porosity in die cast parts, especially those subject to pressure, is done by impregnation.
- Surface Coatings: Anodizing or painting can keep corrosion at bay while still giving interesting or attractive finishes.
- Hot Isostatic Pressing (HIP): This is a common method in aerospace and improves the parts by removing internal holes and thus increasing strength.
With these treatments, you can adjust the part’s performance according to where and how it is going to be used.
Conclusion
By using A360, it is possible to achieve an even mix of castability, durability and resistance to corrosion. It works great for applications in automotive, aerospace and electronics that require high strength. Searching for custom pieces made with A360 alloy?
