Strength in Die Cast Aluminum
Die Cast Aluminum Types of Strength
Aluminum casting uses several methods to measure the strength of the material. Each strength provides engineers with important information about the metal’s properties.
- Tensile strength is the maximum tensile force that aluminum can withstand before breaking. This characteristic helps determine whether a part will break under heavy loads.
- Yield strength is the critical point at which aluminum begins to bend and cannot return to its original shape. The 0.2% offset method is a common method for determining this point. This means the metal has been stretched to the point where it cannot spring back.
- Impact strength measures the ability of aluminum to absorb energy without cracking when subjected to a sudden impact or shock. This is crucial for components that may be subjected to impacts or drops.
These strength tests follow rigorous rules. Standards such as ASTM E8 and ISO 6892 specify the shape of the test specimen, the tensile speed, and the test temperature. These steps ensure the fairness and comparability of test results.
Why Die Cast Aluminum Strength Matters
Strength plays a vital role in aluminum casting. Many industries choose aluminum because it is lightweight and strong. A high strength-to-weight ratio means components are both robust and easy to move.
Automotive companies use aluminum casting to manufacture engine parts and wheels. These parts must be able to withstand pressure and high temperatures without failing. Electronics manufacturers need robust yet lightweight housings to protect their equipment without adding too much weight. Medical devices often use aluminum casting to manufacture tools and housings that must remain strong and resist damage.
When selecting alloys for aluminum casting, engineers consider their tensile strength, yield strength, and impact strength. These properties help them determine whether a part can perform its function. Higher strength aluminum casting alloys enable the manufacture of safer cars, higher-performance electronics, and more reliable medical devices.
Strongest Die Cast Aluminum Alloys

Data shows that A360 has a Brinell hardness of 75 and an elastic modulus of 72 GPa. This alloy can be stretched by 1.6% to 5.0% before fracture, thus exhibiting good ductility. Its fatigue strength ranges from 82 to 150 MPa, making it ideal for parts subjected to repetitive stresses.
| Property | Value |
|---|---|
| Brinell Hardness | 75 |
| Elastic (Young’s) Modulus | 72 GPa |
| Elongation at Break | 1.6 to 5.0 % |
| Fatigue Strength | 82 to 150 MPa |
