Q1. Explain two advantages of ferus allyscompared to non-ferrous alloys Your company received an order to produce nails (fastener). You only have two raw 12.0 materials, which are low carbon steel wire and high carbon steel wire. Your customer required you to deliver products that can be increase in hardness easily using conventional heat treatment. Which raw materials will you choose to manufacture the products? Explain your answer. Q3. With the aid of sketches, compare the microstructure of gray cast irons vs. nodular cast 12.0 irons. Which cast irons that have better capability under tensile loading? Explain your answer 1.0 04. Explain two advantages of nonferrous alloys compared to ferrous alloys.

Explanation / Answer

Advantages of ferrous metals High strength to weight ratiocompared to Non-metalsHeavier than Aluminum andTitanium AlloysHigh quality and durablematerialProne to corrosion by rusting(except stainless steel)Machine-ability Affected by magnetic fieldRecyclable andenvironmentally friendly Disadvantages of ferrous metals Requires more energy to forminto shapes or re-workcompared to Aluminum Alloys

Advantages:1. They are highly ductile and malleable.2. They can be machined easier and can be forged, formed to desired shapes much easier than ferrous alloys.3. They are better conductors of elasticity and heat, hence being used in many electric and thermal applications.4. They can be alloyed to achieve metals that have high strengthLimitation1. Since they are some of the nonferrous alloys are bad conductors of both heat and electricity, they a cannot be used
