Poongsan participates in the defense industry based on its production technology for copper and copper alloy products, which are the basic materials for ammunition, and has large-scale dedicated production lines for each type of ammunition at its Angang and Busan plants, supplying everything from 5.56mm small-diameter ammunition to 155mm howitzer shells for the military. We develop and supply all types of ammunition for use. Poongsan has an integrated production system that not only procures materials and parts such as new ammunition, propellants, and links, but also fills and assembles gunpowder, thereby achieving high competitiveness in quality, price, and delivery. Poongsan produces ammunition of various types and calibers, including anti-aircraft shells, mortar shells, howitzer shells, tank shells, recoilless rifle shells, naval artillery shells, and aviation shells. In particular, in recent years, new types of ammunition have been developed, such as anti-tank ammunition with improved penetration, range extender ammunition with dramatically extended range, Goal Keeper ammunition used in Korean destroyers, and dual-purpose ammunition that can suppress tanks and multiple troops at the same time. We are also achieving great results in improving the performance of conventional ammunition. Additionally, MLRS (Multiple Launch Rocket System) and are responsible for the production of combined warheads including submunitions, which are key components. Poongsan operates an independent quality control organization separate from the production division, and in particular, has a perfect quality assurance system, with each process and lot undergoing strict inspection by a government inspection agency. Poongsan will continue to contribute to independent national defense by improving the performance of existing ammunition based on a consistent production system and advanced quality control system, and by promoting continuous research and development of advanced precision ammunition in line with the changing trends of modern warfare, which is becoming more advanced due to scientific development. It will.

Poongsan has been producing a variety of copper and copper alloy plates, ranging from copper products for everyday life to high-tech industrial materials. These copper and copper alloy plates, which are recognized as high-quality materials at home and abroad, are representative industrial basic materials that are widely used in all industrial fields, including automobiles, electrical and electronics, semiconductors, communications, construction, and machinery. Poongsan has various casting facilities, including the world's largest shaft furnace, a hot mill capable of continuously rolling 6-ton slabs, a tandem mill, and a 20-stage cold rolling mill, as well as various hot and cold rolling facilities and heat treatment furnaces. We are building a large-scale integrated production system from the casting process to finishing processes such as cutting and packaging. Poongsan's rolled products are produced in various sizes depending on the type, ranging from 630mm in width, 0.03mm in thickness, and thickness tolerance to 2/1000mm. These products have accurate specifications and physical properties and a smooth surface thanks to the establishment of a thorough quality control system using cutting-edge inspection equipment. Excellent. Poongsan's copper and copper alloy rolled products are produced in a variety of ways, including pure copper, brass, phosphor bronze, nickel silver, cupronickel, and special alloy (PMC26 and other) depending on the alloy composition and casting method. In particular, in response to market demands for new high-strength copper alloys due to technological advancements such as the Internet of Things and electric vehicles, we have developed new alloys (P1000HS and others) and are applying them to high-tech products requested by customers.
