Manufacturing AMETEK clad materials are manufactured by roll bonding a core or backing with a specialty metal to produce a metallurgically bonded clad. Many metals can be combined through this technique to provide a custom metal with the specific properties that the designer wants.
For example, nickel clad steel is an ideal material for withstanding the high-temperature, corrosive environment to which a hospital sterilizer is exposed. It also works well in products ranging from gourmet cookware to petrochemical processing tanks.
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
product specifications.
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.

Processing
Roll bonding is achieved by processing a specially prepared "sandwich" (layers of backing and cladding materials) through a conventional plate hot rolling mill that reduces the thickness and metallurgically bonds the backing steel to the clad material. Parting compound is used between each clad pack before it is welded and then roll-bonded to yield two separated clad plates.
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.
Fabrication
Clad plate can be fabricated into different shapes which allow designers the freedom to produce custom products for a wide range of applications.
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.
AMETEK's total quality control begins with our selection of high quality raw materials and follows through to an on-time delivery of the finished product to our customers.
Inventory To accelerate delivery times, AMETEK maintains an inventory of A-285 Grade C and A-516 Grade 70 carbon steel, nickel 200, and 304L and 316L stainless steel.
We also:
Provide a raw material inventory and Just In Time programs for repetitive business.
Supply small quantities for specialized requirements.
Maintain a stock of finished plates of various popular combinations including nickel and stainless on carbon steel.
