All-Clad Metalcrafters, LLC is a manufacturer of cookware with headquarters in Canonsburg, Pennsylvania. The company markets its cookware to department and specialty stores in the United States, Canada, Germany, UK and Australia 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 U.S. Mint, ballistics and avionics. 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, the company was purchased by Pittsburgh Annealing Box Co., and was later bought by international company Groupe SEB in 2004.
United States Patents
At the time of its founding, All-Clad distinguished itself from other cookware companies by using 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 extending 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 firm purchases its metals only from United States-based suppliers, including Pennsylvania steel. In recent years, All-Clad has begun outsourcing some of its manufacturing to factories in China; these include products where the bonding of metals is not required (for example kitchen tools and accessories), and regular non-bonded components, or those for which manufacturing constraints exist at the Canonsburg plant (for example, electrical appliances).
The cooking surface is made from Type 304 stainless steel. The primary benefit of stainless steel over other metals is its nonreactive nature which imparts no taste to the food. Some products include a nonstick coating on top of the stainless steel.
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.
In 2000, All-Clad partnered with television chef and personality Emeril Lagasse to develop a line of cookware named "Emerilware". By the end of 2000, Emerilware was contributing one half of the company's 40% growth. Emerilware extended its product line to other specialty items such as cast iron cookware.
Each year in June and December, All-Clad Metalcrafters holds a seconds sale near their headquarters in Canonsburg.
