Brazing Processes
rapidly with low-melting BAg or BCuP filler metals. Silicon, phosphor, and aluminum bronzes should be brazed in a stress-free condition. Special fluxes may be needed with these alloys to prevent formation of oxides that inhibit wetting and flow of the filler metal. Copper-nickel alloys can be readily

Tin
and mold designs should be such that ample metal is fed to remote regions of the mold cavity. Because of their low-melting points, tin-rich alloys can be cast in carbon-steel or rubber molds. Alloys contain from 1 to 8% antimony and 0.5 to 3% copper, and have excellent castability and workability. For spun

Tungsten
Tungsten is a heavy metal that can be classified as a refractory metal, i.e., one with a high melting point. Refractory metals can be useful for their strength at high temperatures and their resistance to corrosion. Tungsten is difficult to melt, so commercial non-alloyed tungsten is produced

When Brazing Beats Welding
material is metallurgically compatible with both base metals and has a melting point lower than the two. Because welding melts the base metals, attempting to join copper (1,981°F melting point) to steel (2,500°F melting point), for instance, would require sophisticated and expensive welding

Refractory Metals
Refractory metals are characterized by their extremely high melting points, which range well above those of iron, cobalt, and nickel. They are used in demanding applications requiring high-temperature strength and corrosion resistance. The most extensively used of these metals are tungsten

New from the Fab Labs: Lightweight but Superstrong Parts
the mud melted though, it would have turned into solid rock. This, of course, is melting. Design and safety considerations. Cormier says for EBM, the finer the powder, the better the surface. "Fortunately, e-machines melt parts in a vacuum. Exposed to oxygen, fine metal and even plastic powders

Materials Engineering: Little-known facts about precious metals
The melting points and densities of the so-called Noble Metals, coupled with their resistance to chemical attack, sets them apart from most other materials. Edited by Jean M. Hoffman Unless you work with precious metal (PM) frequently, your knowledge of these metals is probably limited. The 15-min
