ALUMINUM ALLOY FOR CASTING, ALUMINUM ALLOY MEMBER, AND METHOD FOR MANUFACTURING ALUMINUM ALLOY MEMBER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240158894 titled 'ALUMINUM ALLOY FOR CASTING, ALUMINUM ALLOY MEMBER, AND METHOD FOR MANUFACTURING ALUMINUM ALLOY MEMBER

Simplified Explanation

The abstract describes an aluminum alloy for casting that contains specific percentages of silicon, copper, zinc, and magnesium, with the remainder being aluminum and unavoidable impurities. The alloy is designed to provide a satisfactory mechanical strength for manufacturing aluminum alloy members.

  • The aluminum alloy for casting contains:
 - Silicon: 4.0-7.5%
 - Copper: 1.5-4.0%
 - Zinc: 1.0% or more
 - Magnesium: 0.2-0.8%
 - Aluminum and unavoidable impurities make up the rest
 - Zinc content may range from 1.0% to 5.0%
 - Magnesium content may range from 0.5% to 0.8%
    • Potential Applications:**

- Automotive industry for lightweight components - Aerospace industry for structural parts - Construction industry for durable structures

    • Problems Solved:**

- Achieving satisfactory mechanical strength in aluminum alloy members - Enhancing the performance of cast aluminum components - Improving the overall quality of aluminum alloy products

    • Benefits:**

- Increased mechanical strength - Enhanced durability and longevity - Improved casting properties

    • Potential Commercial Applications of this Technology:**

- Manufacturing of automotive parts - Production of aircraft components - Construction of high-performance structures

    • Possible Prior Art:**

- Prior research on aluminum alloy compositions for casting - Studies on the mechanical properties of aluminum alloys - Patents related to improving the strength of aluminum components

    • Unanswered Questions:**

1. How does the specific composition of silicon, copper, zinc, and magnesium contribute to the mechanical strength of the aluminum alloy?

2. Are there any specific casting techniques or processes recommended for manufacturing aluminum alloy members using this alloy composition?
