White and High Alloy Irons
An important group of alloyed irons that fall outside of the ordinary types of Alloy Die castings have been designated the white and high alloy irons, or the special irons. The high alloy irons are considered separately because their alloy content exceeds 3% and they...
Cast Copper Alloys
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...
Aluminium Casting
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...
Aluminum Casting Alloys
The mechanical properties of alumi- num casting alloys are obtainable only if the chemical and heat treating specifications are followed carefully. It should be noted that the properties obtained from one particular combination of casting alloy, foundry practice and...
Mechanical Properties of Compacted Graphite Iron
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...
Mechanical Properties of Cast Iron
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...
Tech Properties Gray Iron
Microscopically, all gray irons contain flake graphite dispersed in a silicon-iron matrix. How much graphite is present, the length of the flakes and how they are distributed in the matrix directly influence the properties of the iron. The basic strength and...
Aluminum Casting
The term "cast iron" designates an entire family of metals with a wide variety of properties. It is a generic term like steel which also designates a family of metals. Steels and cast irons are both primarily iron with carbon as the main alloying element. Steels...
