Discussion Questions for the Aluminum Case Group: 1. Conduct a S-C-P analysis for the Aluminum industry. Is primary aluminum production industry an attractive(profitable) industry? Why and why not. 2. Using information in the case and the data from the attached spreadsheet‚ construct the industry supply curve for primary aluminum. Please note the marginal costs are used to derive the supply curve and be careful as to what cost items can be counted as “marginal” costs. DO NOT use regressions

1. In general‚ why have many different alloys been developed and used? Many different alloys have been developed and used due to the various properties they have when alloyed which increase their amount of uses. Properties such as increased tensile strength‚ the variation in melting point‚ malleability and luster are all properties that come as a result from alloyed metals. For example‚ carbon and manganese form an alloy called carbon steel‚ which is very hard and can therefore be used to make things

POT TENDING MACHINE PTM is the crucial equipment of large anode pre-baking workshop. It is used in the environment of high temperature‚ large current‚ strong magnetic field and HF gas. It can perform the following procedures ANODE CHANGE: Anode in the pots is changed at an interval of every 27 days since daily 1.5 cm of the anode gets consumed. A carbon block is usually 55 cm high of which only 40 cm can be used up. The main reason behind the anode consumption is the following electrolytic

The yield of a metal from a particular mineral or ore is the mass of metal that can be obtained from a particular mass of the mineral or ore‚ and is often expressed as a percentage. It is possible to use formulae to calculate/predict yields of metals from particular minerals (pure compounds)‚ for ores we have to measure them experimentally. This is because ores are mixtures of the required mineral and unwanted material‚ and‚ being mixtures‚ they have variable composition. Measurement of the yield
