This article focuses on the use of indium and bismuth in low-melting-temperature solders and fusible alloys. It describes how the two elements typically occur in nature and how they are recovered and processed for commercial use. It also provides information on designations, classification, composition, properties (including temperatures ranges), and some of the other ways in which indium and bismuth alloys are used.

The use of gases or molten salts as the quenchant for steel parts is commonly limited to the quenching of high-alloy steel or the carbonizing quenching of low-alloy steel. This article reviews the quenching process of steels with molten metals (quenchant) such as molten lead, molten bismuth, and molten sodium. It also contains tables that list the physical properties of lead, bismuth, sodium, and molten sodium.

This article focuses on aspects that are important for the commercial production of castings. It discusses the modification process in hypoeutectic and eutectic alloys that differ only in the relative volume fraction of primary aluminum and aluminum-silicon eutectic. The article explains how modification changes porosity formation in a casting. It describes the mechanisms responsible for silicon modification, as well as the modifications and changes in eutectic nucleation and the eutectic grain structure. The article reviews the usage of strontium in foundry practices. The growth of silicon eutectic is described to explain effects ancillary to silicon modification. The article also examines the effects of elements, such as phosphorus, antimony, bismuth, magnesium, boron, and calcium, on the silicon structure.

The properties of copper alloys occur in unique combinations found in no other alloy system. This article focuses on the major and minor alloying additions and their impact on the properties of copper. It describes major alloying additions, such as zinc, tin, lead, aluminum, silicon, nickel, beryllium, chromium, and iron. The article discusses minor alloying additions, including antimony, bismuth, selenium, manganese, and phosphorus. Copper alloys can be cast by many processes, including sand casting, permanent mold casting, precision casting, high-pressure die casting, and low-pressure die casting. The article provides information on the types of copper castings and tabulates the nominal chemical composition and mechanical properties of several cast alloys.

This article reviews the melt processing and casting of non-ferrous alloys, such as nickel alloys, titanium alloys, and lead alloys. It describes the lead refining steps, namely, copper drossing, softening, desilvering, zinc removal, bismuth removal, and final refining.
