Latest Patents

Leopold Sauer holds a patent for a unique brass alloy composition. The alloy consists of the following components: Cu: 57-65%; Bi: 0.3-1.5%; Al: 0.4-0.8%; B: 5-15 ppm; impurities 0-1%, with Zn as the remainder. This specific formulation allows the brass alloy to be cast into a chill mold without issues, resulting in a finely grained solidification that is virtually free of shrinkholes. The alloy also permits grain refining with boron, even with a higher Cu content, provided that Mn, Si, and Sb are added in specified amounts while keeping the Fe content to a maximum of 0.25 wt %. Additionally, the alloy's hot shortness is improved by minimizing the Sn content to no more than 0.25 wt %, effectively repressing the occurrence of hard inclusions.
