Metal Bulletin journalists have written about key topics that caught the team’s attention this week in our Comment series.

This week, Metal Bulletin covered the following issues:
- How the push for cleaner emissions has the auto industry looking for ever-lighter metals, and what this could mean for aluminium's place in the market.
- The recent key developments in the European ferro-vanadium market and how there is more than one way to interpret market signals.
- Given zinc's solid set of fundamentals, what is holding back prices for the galvanizing metal?
- There's a hint of the old story of Everybody, Somebody, Anybody and Nobody in the current nickel market.
