Polycrystalline ni-al-cr alloy samples were made from high-purity ni 99.99 pct, cr 99.98 pct and al 99.99 pct, supplied by trillion metals co., ltd., in the preparation of test bars by rapid vacuum melting. raw material was prepared and weighted to an accuracy of 0.001 g prior to the casting
Graphite flotation occurs when low cooling rates and high quotcarbon equivalentquot carbon equivalent carbon 13 silicon combine to produce large nodules that rise during solidification. the result is a depletion of the larger nodules in the lower part of the casting and an accumulation at the upper surface.

The wire bars were then shipped to phelps dodges elizabeth, n.j., facility for rolling into bus bars equivalent to todays astm specification b187, for copper bar, bus bar, rod and shapes. in the late 1970s, the silver bus bars were removed from service, returned to usmr for melting, refining, and casting as 1,000-troy ounce ingots and ...
A guide to marine grade aluminum heres a handy comparison chart of marine grade aluminum alloys. we often get asked which alloy to use, and the answer is quotit dependsquot. there are three alloys that we generally recommend for hull plating and frames 5086, 5083, 5052 and two alloys we recommend for extrusions such as flat bar, tee bar, and continue reading
Alloy 6061 is the most widely used alloy in this series and is often used in truck and marine frames. additionally, the iphone 6 extrusion was made from 6xxx series alloy. 7xxx series. zinc is the primary alloying agent for this series, and when magnesium is added in a smaller amount, the result is a heat-treatable, very high strength alloy.
The use of a master alloy instead of a pure metal can be for economical reasons, since certain elements will have a poor yield or create high losses when melted in pure form. technical issues may also prevent the pure metals from dissolving completely or the required furnace temperature is too high for a basic casting operations equipment.
