What is Cast Aluminum?
Cast aluminum is a specific metal that has gone through one of the several processes known as casting. Essentially, cast aluminum is created when methods such as die casting, mold casting, or sand casting are used to temper the aluminum for use in creating components for many different types of products. Cast aluminum is used for a number of items around the house, as well as machinery and other products that are necessary to the manufacturing of a wide range of goods and services. One of the more common applications of cast aluminum is in the creation of cookware. Just as cast iron is used for skillets, baking pans, and other kitchen essentials, cast iron can also be used for these items. Usually created using the die cast approach, the cookware can withstand the high temperatures required to cook food properly and will remain useful for a number of years with no more than minimal care. Cast aluminum is also used to create outdoor furniture. While not quite as popular as cast iron fur
Cast Aluminum is a soft, lightweight metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Cast Aluminum is nontoxic and nonmagnetic. Cast Aluminum has outstanding corrosion resistance due to a thin surface layer of aluminum oxide that forms when the metal is exposed to air, effectively preventing further oxidation.
Cast aluminum is one of the top choices for outdoor furniture. It is actually exactly what the name indicates, a casting of aluminum. Casting of aluminum furniture has been around for centuries. The process begins by carving a wooden model for the piece that you want to create. Next, the wooden model is used to make metal molds. This is done by pressing the wooden models into the casting sand in order to make an impression. The next step is to take molten lava and pour it into the sand mold that you created. Once the aluminum hardens and cools, the sand is knocked away. You are left with the piece that you wanted to create, in cast aluminum. It is important to note that sand casting of aluminum allows for fine details to be portrayed. This has helped cast aluminum to become a popular choice for indoor and outdoor seating.
When creating a design for a piece of cast aluminum furniture, the craftsmen first carve the design from wood. The resulting wooden model is used to make the metal molds for casting the aluminum. The model is pressed into casting sand to make an impression. The impression is filled with molten aluminum. When it is cooled, the sand is brushed away, leaving a detailed cast. Pieces are assembled and welded into place. The entire piece is finished with a powder-coat paint for long life and durability.
