give a short note on duralumin
Answers
Answer:
Duralumin, strong, hard, lightweight alloy of aluminum, widely used in aircraft construction, discovered in 1906 and patented in 1909 by Alfred Wilm, a German metallurgist; it was originally made only at the company Dürener Metallwerke at Düren, Germany. (The name is a contraction of Dürener and aluminum.)
Explanation:
Duralumin is an alloy made up of 90% aluminum, 4% copper, 0.51% magnesium, and less than 1% manganese.
The alloy can be rolled, forged, and extruded into various forms and products. The tensile strength of duralumin is higher than aluminum, although its resistance to corrosion is poor. ... The light weight and high strength of duralumin when compared to steel enabled its application in aircraft construction.
Answer:
- Duralumin is the trade name of one aluminum alloys. The main alloying constituents are copper(4%) and magnesium(1%) mixed with aluminum (95%).
- Duralumin is a strong, lightweight alloy of aluminum
- It is relatively soft, ductile and easily workable under normal temperature
- it widely used in aircraft constructions
- It's the lightest and least expensive of the all-metals
- It is also reflective and impermeable.
- It is a very good conductor of heat and electricity.
- It is a malleable metal, and can be easily shaped.
- It is an extremely hard alloy
- it is used in vehicle armor in the defense industry
- It can carry heavy loads, and is ductile
