| titleOfInvention | Aluminum alloy plate for battery lid for forming integral explosion-proof valve and method of manufacturing the same |
| abstract | Aluminum alloy plate for battery lid with excellent heat dissipation, deformation resistance, and moldability. It has a small variation in operating pressure and can be used to form an integrated explosion-proof valve with excellent fatigue resistance. An alloy plate and a method for manufacturing the same are provided. Fe: 1.05 to 1.50% by mass, Mn: 0.30 to 0.70% by mass, Ti: 0.002 to 0.15% by mass, and B: Less than 0.04% by mass, with the balance being the balance Is composed of Al and impurities, the Fe / Mn ratio is regulated to 1.8 to 3.5, Si as impurities is less than 0.20% by mass, Cu is less than 0.03% by mass, and Mg is 0.05% by mass. %, V is less than 0.03 mass%, the conductivity is 53.0% IACS or more, the 0.2% proof stress is 40 MPa or more, and the elongation value is 40% or more. Having a recrystallized structure and having both a value of elongation after cold rolling at a rolling reduction of 80% and a value of elongation after cold rolling at a rolling reduction of 90% of 5.0%. An aluminum alloy plate for a battery cover for forming an integral explosion-proof valve, characterized by the above. Further, the average crystal grain size of the recrystallized grains of the recrystallized structure is preferably 15 to 30 μm. |
