Alcoa said Monday that its net income totaled $322 million, or 28 cents a share, in the April-to-June quarter. That compared with net income of $136 million, or 13 cents share, a year ago.
Revenue totaled $6.59 billion compared with $5.19 billion in the previous second quarter.
Alcoa says it saw double-digit growth in sales to the packaging, building and construction and commercial transportation industries.
Improved sales were offset by higher costs for raw materials and a weak dollar.
Alcoa's performance can reflect economic trends because its products reach across a broad range of businesses.
