Inventor: PARK EUN SOO
IPC: C22C1/10
Filed: 2021-03-23
Abstract: The present invention relates to a brass alloy for drinking water including stainless steel precipitate and a manufacturing method thereof. More specifically, an objective of the present invention is to create an alloy from materials which can make up stainless steel among elements having a monotectic reaction with a brass alloy to selectively precipitate (separate) stainless steel spherically to promote property improvement of brass material and minimize the usage of lead which causes environmental problems. Moreover, economic efficiency was maximized by using scrap material instead of directly using relatively extensive elements making up stainless steel such as Cr and Ni. The brass alloy for drinking water developed through the present invention (1) is manufactured through scrap to have economic efficiency and (2) is eco-friendly by reducing the lead content. Nonetheless, the brass alloy for drinking water (3) has a second phase precipitate microstructure of spheres (separation) of conventional flexible brass to improve machinability. Moreover, (4) properties such as strength and corrosion resistance can also be improved through stainless steel precipitation which is high-strength/corrosion-resistant precipitate. Accordingly, a brass material with multifunctional properties overcoming the disadvantages of conventional flexible brass materials can be provided in a more economic manner.
