NYSE Closing Bell: AMETEK Chairman and CEO Frank Hermance marks AMETEK's 75 years as a NYSE-listed company
ALCOR TM 7 Ply
These two stainless steels are bonded to one side of a heat conducting aluminum core with a solid T-304 layer on the other side. ALCOR 7 offers a unique combination of properties that will produce cookware usable on any type of range or cooktop: gas, resistance-heated electric, and induction-heated electric. The use of ferritic stainless steel to add magnetic properties allows the utensil to be designed and produced using the same tools as the regular ALCO 5 Ply product without special edge treatment.
The magnetic or induction properties of ALCOR 7 are obtained from the special ferritic stainless steel layer under the thin T-304 stsainless steel outer layer. The special ferritic stainless steel has a tightly controlled analysis with special additions of titanium for optimum properties.
The relatively thin layers of T-304 and ferritic stainless steel allow for more aluminum to be used for maximum, even heating--no hot spots. The heavy aluminum prevents "hot spots" that can be produced by gas, electric, and induction heating. A thick magnetic layer, combined with a thin aluminum layer as used by other 7 Ply products, produces cookware that will develop "hot spots."
High-Performance Clad Metal Manufacturing
Our clad materials are available in widths to 126 inches, lengths to 400 inches, and thicknesses ranging from 3/16 to 1-1/2 inch. Cladding on the steel backing can be supplied in a range of thicknesses from 5 percent to 40 percent of the overall material thickness.
Standard composites available are stainless clad aluminum, nickel clad steel, stainless clad steel, titanium clad aluminum, A276 clad steel, and Inconel* clad steel.
AMETEK metallurgists are always available to assist you with developing custom
As an additional customer service, we can further process clad sheet and plate to meet specifications for close dimensional and flatness tolerances, glass beading or sand blasting one or both sides, cutting to circles or supplying formed heads.

After cutting to finish size, the bonded plates are cleaned by blasting with an abrasive that is mixed with glass beads to obtain a clean, relatively bright surface, both top and bottom, if desired.
Forming: Clad materials can be cut and formed by shop operations, including shearing, plasma cutting, drawing, bending, hot forming, machining, drilling and punching.
Welding: Fusing of clad materials is usually done by first welding the backing material using appropriate filler material and then welding the clad side with a welding electrode or filler metal appropriate to that surface.
Quality Control, Testing
Generally, clad plate is produced to meet or exceed either ASME A-264 or ASME A-265 codes. To meet these specifications, AMETEK routinely performs tensile tests, shear tests, hardness, bend tests and impact tests (Charpy V-Notch) on modem testing equipment. Other services, as specified by the customer, are also available such as ultrasonic testing, thermal treatment and saw cutting.
