Case Preview


AluCo is one of the world’s largest aluminum producers. It also makes a wide range of alloys, which combine aluminum and other elements and have specific properties.

The company has hired you to look at AluCo Closures, a subsidiary that makes two alloys – the 3-series and the 8-series – which are used to make bottle tops (closures).

The 3-series is harder and is used in water and carbonated drinks. The 8-series is softer and sold to spirits companies.

AluCo historically has maintained the highest product quality in the industry and the company maintains a 65% market share in both markets.

Can you tell me if you think this a good business to be in?

BCG Case Study Overview

Your client is an aluminum producer. In this BCG case study, you are being asked to examine the market to determine if one of your client’s subsidiaries is in a good position to succeed going forward.

You can use the Market Study Framework to solve this case, but we caution you against boxing yourself into that framework alone. The best candidates blend frameworks and their own business understanding to build a custom structure for the problem.

The BCG case study has a qualitative difficulty score of 3 out of 4 and no math exhibits. This an advanced case interview you might be given in a final round BCG interview.

BCG Interview Tips

BCG is looking for candidates that are structured and able to clearly and concisely communicate that structure.

Focus on creating a structure that is crystal-clear, and verbalize each part of your process..

In this BCG case study, focus on 2 things:

  • Timing yourself as you run through the case: 2min for structure, 5min for math, 2min for brainstorming, and 2min for a conclusion
  • Concise communication and overall polish
