Which of the following statement is incorrect about duralumin?a)It is ...
Duralumin is an aluminum alloy that contains copper, manganese, and magnesium. It is widely used in the aerospace industry due to its high strength-to-weight ratio. However, the statement that is incorrect about duralumin is:
Incorrect statement: It has good machining properties
Explanation:
Machining properties refer to the ability to cut and shape the material using various methods such as drilling, milling, turning, etc. Duralumin is a tough material that is difficult to machine, and it requires special tools and techniques to work with. Some of the challenges of machining duralumin include:
1. Work hardening: Duralumin hardens rapidly during machining due to the heat generated by the cutting process. This can cause the material to become brittle and prone to cracking.
2. Chip formation: Duralumin produces long, stringy chips that can clog the cutting tool and damage the workpiece.
3. Tool wear: Duralumin is abrasive and can cause rapid wear of the cutting tool, leading to reduced tool life and increased machining costs.
Despite these challenges, duralumin is still widely used in the aerospace industry due to its high strength and corrosion resistance. Machining duralumin requires specialized knowledge and equipment, and it is typically done by experienced professionals using CNC machines or other advanced machining techniques.
