Physical properties of iron
Pure iron has no industrial importance: relatively soft, malleable, ductile, magnetic, melts at 1538 C, density 7.87 g/cm3.
The idea, in English
Pure iron has no industrial importance: relatively soft, malleable, ductile, magnetic, melts at 1538 C, density 7.87 g/cm3. Its physical properties depend on its purity and on its impurities, so many steels and iron alloys with specific properties are made.
Explain in Egyptian Arabic
الـ iron النقي مالوش أهمية صناعية: هو relatively soft، و malleable و ductile و magnetic، وبينصهر عند 1538 C، والـ density بتاعته 7.87 g/cm3. الـ physical properties بتاعته بتعتمد على درجة نقاوته وعلى الشوائب اللي فيه، وعشان كده بيتعمل منه steels و iron alloys كتير بخواص محددة.
المطلوب
تشرح ليه الـ iron النقي مش بيتستخدم، وليه الـ alloys هي اللي بتتستخدم.
Common misconceptions
- Pure iron is very hard.
No. Pure iron is relatively soft, as well as malleable and ductile. That is why pure iron has no industrial importance and iron is used as steels and alloys with the properties needed.
Explain in Egyptian Arabic
لأ، الـ iron النقي relatively soft، يعني الـ hardness بتاعته قليلة.
- Pure iron is the most useful form of iron.
The opposite
pure iron has no industrial importance because it is relatively soft. What industry uses are steels and iron alloys, made with specific properties.
Explain in Egyptian Arabic
بالعكس، الـ iron النقي مالوش أهمية صناعية عشان هو relatively soft. اللي بيتستخدم فعلًا هو الـ steels والـ iron alloys اللي بتتعمل بخواص محددة.
