Lead and Lead Alloys

This comprehensive guide explores lead and its alloys, tracing their historical significance from ancient civilizations to modern industrial applications. The article details various grades of lead, their compositions, and unique properties that make them valuable in diverse applications.

MAB and NAB alloys

Aluminum bronzes have widespread applications where a specific level of durability and resistance is required. Two of the most common are the Manganese Nickel Aluminum Bronze (MAB) and Nickel Aluminum Bronze (NAB).
Depending on the job, there are a range of comparisons which can be made to ensure the correct material is selected including differences in mechanical properties, weight saving potential, and corrosion resistance.

Machining Nonferrous Metals

Some of the alloys of aluminum have been machined successfully without any lubricant or cutting compound, but in order to obtain the best results, some form of lubricant is desirable. Tools for aluminum and aluminum alloys should have larger relief and rake angles than tools for cutting steel.
Magnesium alloys are readily machined and with relatively low power consumption per cubic inch of metal removed. The usual practice is to employ high cutting speeds with relatively coarse feeds and deep cuts. Exceptionally fine finishes can be obtained so that grinding to improve the finish usually is unnecessary.
Machining of zinc alloy die-castings is mostly done without a lubricant. For particular work, a lubricant may be used to advantage.

Magnesium and Magnesium Alloys

This comprehensive article explores magnesium and its alloys, highlighting their significant role in engineering applications. The text examines the unique properties that make magnesium alloys valuable in industrial applications, particularly their exceptional strength-to-weight ratio, superior machinability, and cost-effectiveness. With a specific gravity of 1.74, magnesium stands as the lightest structural metal available, offering substantial weight advantages over aluminum and steel.

Magnesium Lithium Alloys

As a widely used group of alloys, Mg-Li alloys are improved through treatments including precipitation hardening, solution strengthening, grain and sub-grain optimization, and dislocation density strengthening.
Solution strengthening for example, is one of the most effective mechanisms used to improve the mechanical properties of Mg-Li alloys and its composites and through a series of studies we explore the results.

Magnesium-Zirconium Alloys

Weight savings, good mechanical properties, corrosion resistance are key factors in making magnesium-zirconium alloys a preferred structural material choice in automotive and aerospace applications.
Zirconium is particularly useful for influencing grain size control for which magnesium alloys without this inclusion have a tendency to display characteristic grain growth.
