History


The present-day materials business is distantly descended from Superior Stone, an aggregates company founded in 1939 in Raleigh, North Carolina. In 1959, the company was purchased by the American-Marietta Corporation, which merged with the Glenn L. Martin Company a year later to form the Martin Marietta Corporation. In 1971, Martin Marietta acquired Harvey Aluminum, a company which made aluminum oxide, aluminum ingot and aircraft grade aluminum sheet. Martin Marietta merged with Lockheed Corporation in 1995, and a year later, Martin Marietta Materials was spun off as an independent company, with Lockheed Martin retaining various aerospace, defense, and other manufacturing lines of business.
Martin Marietta's Magnesia Specialties business provides a full range of magnesium oxide, magnesium hydroxide and dolomitic lime products.
