Gravity Casting /Low Pressure Casting Aluminum Alloy Analysis
Gravity casting, as a crucial metal forming process, is widely used in industries such as automotive, aerospace, and mechanical manufacturing. Aluminum alloys, owing to their excellent strength-to-weight ratio, good castability, and corrosion resistance, are among the most commonly used materials in gravity casting. Based on the provided table of chemical composition control limits for aluminum alloys, this paper offers a professional analysis of the commonly used aluminum alloy grades in gravity casting.
Main Aluminum Alloy Grades and Their Characteristics
1. ZL114A/A357.0 Series Aluminum Alloy
ZL114A (A357.0) belongs to high-magnesium Al-Si-Mg alloys:
- Increased Mg content:
0.45–0.75% | Significantly enhances age strengthening effects - Ti addition:
0.08–0.25% | For grain refinement - Impurity control:
Fe ≤ 0.2% | Extremely low levels of other impurities
Applications:
This alloy achieves exceptionally high strength after T6 heat treatment, commonly used in high-stress structural components.
2. ZL104/Al-Si10Mg Series Aluminum Alloy
ZL104 (Al-Si10Mg) represents high-silicon aluminum alloys:
- High Si content:
8.0–11.0% | Excellent fluidity and hot tear resistance - Moderate Mg content:
0.15–0.50% | Ensures effective strengthening - Mn addition:
0.2–0.5% | Enhances strength and heat resistance
Applications:
Particularly suitable for thin-walled complex castings, widely used in automotive engine blocks and similar components.
3. ZL107/319.0 Series Aluminum Alloy
ZL107 (319.0) is a copper-containing Al-Si alloy:
- Cu content:
3.0–4.0% | Significantly improves high-temperature strength - Si content:
6.5–7.5% | Ensures good castability
Applications:
Primarily used for engine components requiring elevated high-temperature strength.
