Title:
ELECTRODE MATERIAL FOR RESISTANCE WELDING OF ALUMINUM AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP2774239
Kind Code:
B2
Abstract:
PURPOSE: To provide an electrode material capable of prolonging the service life of an electrode five or more times those of conventional ones at the time of spot welding of aluminum and also capable of welding an aluminum sheet similarly to a steel sheet, e.g., in an automobile assembly line.
CONSTITUTION: An ingot consisting of, by mass, 0.03-0.5% Ag, 0.004-0.10% O, and the balance Cu with inevitable impurities, is hot-worked, subjected, if necessary, to cold working and process annealing, and then subjected to final cold working at a draft of 5-90%, preferably 10-75%.
