Battleships thundered and warplanes flew. On April 23, a naval parade marking the 70th anniversary of the founding of the Chinese Navy was held. Equipped with the "aluminum southwest aluminum made" of the "national heavy equipment" split the waves, toward the deep blue, with the majestic potential to accept the review. Following the appearance of the South China Sea parade last year, "ChalCO Southwest Aluminum" once again made a stunning appearance in the Qingdao Sea parade, offering a generous gift for the 70th anniversary of the founding of New China with practical actions.

　　Chinalco Southwest Aluminum (Group) Co., Ltd. provided a large number of high-precision aluminum alloy materials for the naval vessels and aircraft that appeared in the big parade. Among them, the phased array radar, flame baffle, arrester system, lifting platform, anti-skateboard and other parts on aircraft carriers, fighters, early warning aircraft, helicopters and other warplanes on the plate, forgings, profiles and other key aluminum alloy materials are mostly from aluminum southwest aluminum. These materials have the characteristics of high strength, high toughness, high precision and long life, and have extremely high requirements for product process and quality control.

　　As a key component on the aircraft carrier, the flame baffle is used to block the huge air flow from the tail of the carrier aircraft during takeoff and the temperature of up to 1200 degrees, which has high requirements for high temperature resistance, impact resistance and corrosion resistance. Through repeated trial production, Chinalco Southwest Aluminum has overcome the difficulties of ultra-wide, porous, ribbed, complex cross-section molding and welding quality requirements, and has continuously "tempered" in quality control and process optimization to ensure the stability and reliability of the flame baffle. "The country's heavy instrument" criss-crossing the sea, pursuing the dream of deep blue, "Aluminum Southwest aluminum" has experienced a big test.

　　As the backbone of the aluminum processing industry, Chinalco Southwest Aluminum has always shouldering the national mission, adhering to independent innovation, breaking foreign monopolies, constantly achieving the supply and upgrade of key aluminum alloy materials for weapons and equipment, constantly improving the independent controllability of key aluminum alloy materials in China, striving to achieve a generation of materials and equipment, and boosting the better and faster development of China's national defense military industry and aerospace industry. To contribute to the realization of the Chinese dream of the great rejuvenation of the Chinese nation.
