Melting actually gets the metal hot enough that it changes from solid to liquid. Sintering is different because the heating process is highly controlled. You get the enhanced properties you need without having to melt the metal. One of the great things about sintering is that you can easily ma...
● The best way to clean the stainless steel finish of your appliance is: with a stainless steel cleaner or polish which can be sold as a liquid, paste or foam. Use soft, clean rags, do not use brushes or scouring pads. ● Glass cleaner can leave streaks on the stainless steel finish...
Powder metallurgy is a method by which very tiny ingots are formed. The liquid steel is dripped through a nozzle and is “atomized” by liquid or gas sprays that near-instantly solidify the steel as powder. Typically nitrogen is used in the production of tool steel. Each particle of the po...
Common desktop 3D printing uses plastic filaments that are either melted into liquid form or heated to be more pliable. Vat polymerization methods likestereolithography (SLA), digital light processing (DLP), and liquid crystal display (LCD) use light to set or “cure” each liquid filament layer...
When shipped, it must either be in liquid form or transformed into ammonia. Both are expensive processes, and liquefying hydrogen is technically challenging as well: it needs to be cooled down to –252°C, one of the lowest boiling points of all the elements. Facilitating cooperation among ...
Recycling aluminum extrusion scrap involves multiple steps to ensure the material is clean and ready for reuse: Shredding—Aluminum scrap is shredded into smaller pieces, allowing faster melting and easier processing. Melting—The shredded aluminum is melted down into liquid form. Properly sorted and ...
At extremely low temperatures, metals conduct electricity better than any known substance at room temperature. This phenomenon is calledsuperconductivity. A substance that behaves in this way is called asuperconductor. Ionic conductors are typically liquid solutions with element ions suspended in them. Th...
Melting point is a crucial physical property. The temperature at which a substance changes from a solid to a liquid state directly impacts how that substance is handled and applied. Aluminum has a melting point of approximately 1220°F. Relative to other metals, this is about double the ...
some of the moisture may condense. The dew point is the temperature to which air must be cooled to become saturated with water vapor. It is assumed that air pressure and water content are constant. When cooled further, the airborne water vapor will condense to form liquid water (dew). When...
In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are not brittle). They have a broad range of melting temperatures (e.g., mercury is a liquid at room temperature, gallium will melt ...
