On the subject matter of this web site the materials handbook has to say:

“…ALLOY. A very old term for the admixture of a precious metal with a metal of lesser value, or with a base metal. This term refers broadly to the combination of at least two atoms or elements. More generally, however, the principal element is a metal, and all are intended for a specific purpose as opposed to the minute quantities of various elements retained from the ore or introduced during the refining process and called impurities. In most cases, the two or more elements are metals, metal alloys being the most common kind. There are notable exceptions, however, as in the case of steel, which is fundamentally iron alloyed with small amounts of carbon, a nonmetal. In recentyears, the term plastic alloy also has been applied to plastics.
Metal alloys are more specifically described with reference to the major element by weight, which is also called the base metal or parent metal. Thus the terms aluminum alloy, copper alloy, etc. Elements present in lesser quantities are called alloying elements. When one or more alloying elements are present in substantial quantity or, regardless of their amount, have a pronounced effect on the alloy, then they, too, may be reflected in generic designations…”

The Materials Handbook is an encyclopedic, A-to-Z organization of all types of materials, featuring their key performance properties, principal characteristics and applications in product design. Materials include ferrous and nonferrous metals, plastics, elastomers, ceramics, woods, composites, chemicals, minerals, textiles, fuels, foodstuffs and natural plant and animal substances –more than 13,000 in all. Properties are expressed in both U.S. customary and metric units and a thorough index eases finding details on each and every material.

Introduced in 1929 and often known simply as “Brady’s,” this comprehensive, one-volume, 1244 page encyclopedia of materials is intended for executives, managers, supervisors, engineers, and technicians, in engineering, manufacturing, marketing, purchasing and sales as well as educators and students.
Of the dozens of families of materials updated in the 15th Edition, the most extensive additions pertain to adhesives, activated carbon, aluminides, aluminum alloys, catalysts, ceramics, composites, fullerences, heat-transfer fluids, nanophase materials, nickel alloys, olefins, silicon nitride, stainless steels, thermoplastic elastomers, titanium alloys, tungsten alloys, valve alloys and welding and hard-facing alloys.
Also widely updated are acrylics, brazing alloys, chelants, biodegradable plastics, molybdenum alloys, plastic alloys, recyclate plastics, superalloys, supercritical fluids and tool steels.
New classes of materials added include aliphatic polyketones, carburizing secondary-hardening steels and polyarylene ether benzimidazoles. Carcinogens and materials likely to be cancer-causing in humans are listed for the first time.
