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
ZL101A/A356.0 Series Aluminum Alloy
ZL101A (A356.0) is an improved version of ZL101, with the following key differences:
- Stricter impurity control:
Fe content limited to < 0.2% (vs. 0.9% in standard ZL101) - Reduced Mn content:
≤0.10% (vs. ≤0.35% in standard ZL101) - Addition of Ti:
0.08–0.20%, serving to refine grain structure
Applications:
This high-purity aluminum alloy is particularly suitable for castings requiring high mechanical performance and surface quality, such as aerospace structural components.
