PROBLEM TO BE SOLVED: To provide a manufacturing method for a material for a titanium clad utensil which has light weight, excellent usability and heat conductivity, a surface having excellent lubricity keeps food clean without scorching cooked items, and is usually kept clean by allowing seasoning such as oils and fats, salt or soy source adhered thereto to be easily wiped out with a disk towel or paper or the like. SOLUTION: Aluminum to be a base layer is heated at 370-430 deg.C and maintained, and titanium, stainless steel or steel which covers a surface of the aluminum is heated at 150-240 deg.C and maintained. They are laminated so as to be three-layer-order such as titanium-aluminum-titanium, titanium- aluminum-stainless steel, or titanium-aluminum-iron, or two-layer-order such as titanium-aluminum, integrally joined by rolling at single pass under a draft of 20-40%, and diffused and annealed at 350-430 deg.C. |
