The state of global manufacturing in 3 charts

Aluminum giant Alcoa just reported second quarter earnings, unofficially starting second quarter earnings season.

Alcoa's report was a miss on the bottom line as earnings came in at $0.19 against expectations for a profit of $0.22. Revenue, however, came in better than expected, as the company brought in $5.9 billion in the second quarter, topping estimates for revenue of $5.81 billion.

And as one of the major aluminum producers in the world, Alcoa is seen as a bellwether for global manufacturing, and Alcoa's overall outlook for the world is generally okay.

In its aerospace segment, Alcoa sees sales growth up 8% to 9% this year, while automotive growth should be up 2% to 4% on strong growth in China.

The only major soft spot for Alcoa's outlook is heavy duty trucks and trailers, where the company says production in its China market is down 34.1% this year.

And so in just 3 slides, here is the manufacturing bellwether's full outlook for world manufacturing in 2015.
