Die-casting can be done using a cold chamber or hot chamber process. 1. In a cold chamber process, the molten metal is ladled into the cold chamber for each shot. There is less time exposure of the melt to the plunger walls or the plunger. This is particularly useful for metals such as Aluminum, and …
Alloy Die Casting Description: Aluminum Alloy Die Casting A380 is the most common of the aluminum die casting alloys. It offers the best combination of casting and product properties. It is used for a wide variety of products such as garden equipment, chassis for electronic equipment, engine brackets, housings for automotive alternators, starters and water …
AQL Acceptable Quality Level. A quality level established on a prearranged system of inspection using samples selected at random. As-cast condition Casting without subsequent heat treatment. Backing sand The bulk of the sand in the flask. The sand compacted on top of the facing sand that covers the pattern. Binder The bonding agent used as an additive to mold …
The different grades of malleable iron are essentially the result of different heat treatments. Just as a medium carbon steel can be heat treated to a wide range in properties so can malleable iron, but malleable is even more versatile. The combined carbon content, on which heat treatment depends, can be adjusted from none, as …
For the purpose of this article, carbon steels are considered to be those steels in which carbon is the principal alloying element. Other elements that are present and that, in general, are required to be reported are manganese, silicon, phosphorous and sulfur. In a sense, all of these elements are residuals from the raw materials …

A Primer on Selecting Cast Copper Alloys Traditionally, cast copper alloys were classified by a variety of systems including the ASTM letter-number designation based on nominal composition, by trade names, and by descriptive terms such as “ounce metal,” “Navy M” and so forth. However, with technological developments, new alloys were produced and existing alloys modified, …
A Basic Guide to Choosing Aluminum Casting Alloys Part 2 Alloys 319.0, A319.0, B319.0 & 320.0 Alloys 319.0 and A319.0 exhibit very good castability, weldability, pressure tightness and moderate strength. They are very stable alloys (i.e., their good casting and mechanical properties are not affected seriously by fluctuations in the impurity content). Alloys B319.0 and …
Compacted graphite iron is a fairly recent addition to the family of commercially produced aluminum casting irons. Its characteristics are intermediate to those of the gray and ductile irons. As in gray iron, the graphite in CG iron is in the form of interconnected flakes. This facilitates the production of sound castings, especially those …

Ductile iron is characterized by having all of its graphite occur in microscopic spheroids. Although this graphite constitutes about 10% by volume of ductile iron, its compact spherical shape minimizes the effect on mechanical properties. The graphite in commercially produced ductile iron is not always in perfect spheres. It can occur in a somewhat irregular …
