All-Clad Metalcrafters, LLC is a U.S. manufacturer of cookware with headquarters in Canonsburg, Pennsylvania. The company markets its cookware to department stores and specialty stores in the United States, Australia, Canada, Germany, and the UK, along with All-Clad bonded ovenware, kitchen tools, and kitchen accessories
The business was founded by metallurgist John Ulam, in 1967, as a manufacturer of bonded metals, including coinage for the U.S. Mint, avionics, and ballistics. The company was instrumental in the shift to bonded metal coins.
The company’s move to cookware happened by accident, when Ulam made a pan for his personal use. All-Clad Metalcrafters was established in 1971 to sell this cookware. Bloomingdale’s picked up the brand two years later, for its upscale housewares department. In 1988, All-Clad Metalcrafters was purchased by Pittsburgh Annealing Box Co. and in 2004, it was bought by the international company Groupe SEB.[
