These are as follows:2Copper Alloy UNS No.2Previous DesignationC96200 Alloy AC96400 Alloy B1.2 Castings of these alloys are used primarily forcorrosion-resistance applications such as in construction andfor pressure vessels, par
4、ticularly in marine pumps, valves, andfittings.1.3 These alloys are considered weldable, but they may beordered with a weld test to ensure weldability. When extensivewelding is to be performed on the casting, weldability testsshould be specified in the ordering information (5.2.6)toensure proper wel
