SAN FRANCISCO — Apple is seeding the next generation of American-made glass for its iPhones and iPads, and its investments may have the side benefit of helping the company win favor in Washington.

Apple announced Friday that it was giving $200 million to Corning, which makes the tough, scratch-resistant face for every iPhone and iPad, to support the glass maker’s efforts to develop and build more sophisticated products at its factory in Harrodsburg, Ky.

Corning has made the glass for every iPhone since the original 10 years ago. Apple’s investment, the first from the technology giant’s $1 billion fund to promote advanced manufacturing in the United States, will help Corning develop thinner, more versatile glass for iPhones as well as other product lines that Apple is exploring, such as screens for self-driving cars and augmented reality glasses.

The move goes beyond Apple’s traditional practice of subsidizing suppliers, said Tim Bajarin, president of the technology consulting firm Creative Strategies.
