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 French conglomerate Groupe SEB.
United States patents
At the time of its founding, All-Clad used a patented "roll bonding" process by which metals are sandwiched together and then formed into a cooking vessel. The company derived its name from this cladding process, which is applied not only on the bottom but extends all the way up the sides of each cooking vessel. The company has been issued several patents by the United States Patent and Trademark Office (USPTO).                
The cookware is available in a combination of exterior metal finishes including stainless steel, brushed stainless steel, brushed aluminium alloy, black hardcoat anodized aluminium, copper, and copper core.
