- Post-casting treatments (e.g., heat treatment, machining)
Choosing the right alloy involves balancing these factors to meet your specific project needs. A reputable Aluminum Die Casting service provider can offer valuable guidance in this selection process.
3. Most Common Aluminum Die Casting Alloys
A380 Alloy
A380 is one of the most widely used alloys in Aluminum Die Casting. Its popularity stems from its excellent combination of properties:
- Composition: 8.5% silicon, 3.5% copper, 1% iron
- Properties: Good fluidity, pressure tightness, and resistance to hot cracking
- Advantages: Excellent castability, good mechanical properties, and corrosion resistance
- Applications: Automotive components, household appliances, and general engineering parts
A383 Alloy
A383 is similar to A380 but with some key differences:
- Comparison with A380: Higher silicon content (10-12%)
- Unique benefits: Superior pressure tightness and excellent thin-wall capabilities
- Use cases: Complex, intricate castings where pressure tightness is crucial
A360 Alloy
A360 offers a different set of characteristics:
- Key characteristics: Lower copper content, higher magnesium content
- Specific applications: Marine hardware, food handling equipment, and architectural applications due to its superior corrosion resistance
Other Notable Alloys
- A413: High silicon content (11-13%), excellent for thin-walled castings
- B390: High silicon and copper content, used for wear-resistant applications
- 518: Contains magnesium, offering good corrosion resistance and weldability
