Abstract
The method is for manufacturing a clad material (30), which includes: clad rolling for rolling and bonding a first metal plate (131) made of stainless steel, a second metal plate (132) made of Cu or a Cu alloy, and a third metal plate (133) made of stainless steel in a state in which the first metal plate, the second metal plate, and the third metal plate are stacked in this order. The clad rolling is performed with a pressure-bonding load of 4.4×103 N/mm or more. The second layer is made of Cu or a Cu alloy. The third layer is made of stainless steel. The clad material has an overall thickness of 1 mm or less.
Claims4
A method for manufacturing a clad material (30), comprising:
- clad rolling for rolling and bonding a first metal plate (131) made of stainless steel, a second metal plate (132) made of Cu or a Cu alloy, and a third metal plate (133) made of stainless steel in a state in which the first metal plate, the second metal plate, and the third metal plate are stacked in this order;
- wherein
- the clad rolling is performed with a pressure-bonding load of 4.4×103 N/mm or more such that the clad material including a first layer made of stainless steel, a second layer made of Cu or a Cu alloy and roll-bonded to the first layer, and a third layer made of stainless steel and roll-bonded to a side of the second layer opposite to the first layer, the clad material having an overall thickness of 1 mm or less, in which in a cross-sectional view along a stacking direction, a minimum thickness of the first layer in the stacking direction and a minimum thickness of the third layer in the stacking direction are 70% or more and less than 100% of an average thickness of the first layer in the stacking direction and an average thickness of the third layer in the stacking direction, respectively, is produced.
