TL;DR: The Unified Numbering System (UNS) is the accepted alloy designation system in North America for wrought and cast coppers and copper alloys as mentioned in this paper, which is used to identify marine alloys.
Abstract: Copper was among the first metals to be put into utilitarian service. The Unified Numbering System (UNS) is the accepted alloy designation system in North America for wrought and cast coppers and copper alloys. Identification is by five-digit numbers preceded by the letter C. Preferred marine alloys include copper nickels, which exhibit the highest corrosion and erosion resistance among copper metals, and also offer relatively high strengths, and aluminum bronzes, which are stronger still, as well as ultrahigh-strength beryllium copper, inhibited aluminum brass, phosphor bronzes, arsenical admiralty brass, and nickel silvers. Copper alloys that perform well in seawater are also often acceptable for use with industrial and process. Copper casting alloys are widely used in the manufacture of plumbing, electrical, and mechanical products and for bearings and industrial valves and fittings. Copper nickels, aluminum bronzes, silicon bronzes, manganese bronzes, and tin and phosphor bronzes should be considered for such environments.

TL;DR: In this article, the average crack depth, p, was found to be proportional to the grain size in brass, and the authors concluded that the grain-size effect came from stage I cracking.

TL;DR: In this paper, a combining etching and heat treatment approach was used to achieve a super-hydrophobic surface on brass, which exhibited good and persistent corrosion resistance in 3.5% NaCl aqueous solutions.

TL;DR: In this paper, the authors tested the corrosion resistance of five commercial metals (aluminum, brass, copper, steel and stainless steel) in contact with two salt hydrates, commonly used as PCM, with a melting temperature in the range of 48 to 58°C (sodium acetate trihydrate and sodium thiosulfate pentahydrate) in experiments with a duration up to 70 days.
Abstract: Efficient energy storage is one of the biggest problems facing alternative energy technologies. In whatever form the energy is stored, an alternative energy system usually requires a storage buffer between carrying energy input and the varying energy demand regime at the output end of the system. A method of energy storage is the use of the latent heat from Phase Change Materials (PCMs), for example salt hydrates. In this paper we tested the corrosion resistance of five commercial metals (aluminum, brass, copper, steel and stainless steel) in contact with two salt hydrates, commonly used as PCM, with a melting temperature in the range of 48 to 58°C (sodium acetate trihydrate and sodium thiosulfate pentahydrate) in experiments with a duration up to 70 days. The results demonstrated that brass and copper should be avoided when sodium acetate trihydrate is used in long term applications, but aluminum, steel and stainless steel can be used without problem. When the salt hydrate used is sodium thiosulfate pentahydrate, brass and copper should not be used in any case, aluminum and stainless steel can be used, and steel in contact with graphite should be monitored because corrosion could appear after some time of use.

TL;DR: In this article, a new modelling of the constitutive behavior of brass specimens was proposed to evaluate the size effects on the flow stress, and the material parameters related to this model were identified by an inverse method using the experimental measurements for tensile and bulging tests.
