Alcoa will build a new plant in Indiana and expand two other factories to increase production of aluminum-lithium alloys to meet rising demand from the aerospace industry.

The Pittsburgh-based aluminum company, which has a plant in Auburn, has begun work on a 115,000-square-foot plant near its current operation in Lafayette.

Alcoa is spending more than $90 million to build the plant, which will be able to produce more than 20,000 metric tons of aluminum lithium.

New alloys introduced last year allow manufacturers to build much lighter aircraft, which are selling at a premium because of potential fuel savings, one of the airline industries’ biggest costs.

Orders for manufacturers like Boeing Co. are on the rise. The company posted a 20 percent jump in net income Wednesday, driven by orders from the commercial aircraft industry. The company delivered 128 commercial planes during the quarter, up from 116 a year ago.

Alcoa plans to begin production at the new Indiana plant by late 2014. It will hire about 150 workers during the construction phase.

The manufacturer also will expand aluminum-lithium capacity by 30 percent at its plants near Upper Burrell, Pa., and add casting capacity at the Kitts Green plant in Birmingham, United Kingdom.

Alcoa spokesman Kevin Lowery said these expansions will add an incremental number of jobs but declined to release costs for the two projects. He said the bulk of Alcoa’s investment in the expansions will be incurred at the Indiana plant.
