Ask a Metallurgist: Wrought Iron vs Cast Iron | Metal ...

The term "wrought iron" is often misused today; it is commonly used to describe designs similar to historical wrought iron pieces—regardless of the metal used. Mild steel that has been machine-bent into shape in a cold state or cast steel and iron pieces that have been painted black are both regularly mislabelled as wrought iron work.

Aluminum Alloys 101 | The Aluminum Association

2015-7-29 · An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include iron, silicon, copper, magnesium, manganese and zinc at levels that combined may make up as much as 15 percent of the alloy by weight. Alloys are ...

How springs is made

Padlocks were widely used in the ancient Roman empire, and at least one type used bowed metal leaves to keep the devices closed until the leaves were compressed with keys. The next significant development in the history of springs came in the Middle Ages. A power saw devised by Villard de Honnecourt about 1250 used …

Aluminum Foundry : 6 Steps

 · Ceramic The first crucible (a container used to hold the molten metal) we tried was a ceramic mug with the handle broken off. This lasted about 15 minutes before cracking, however because the coals were packed around it, the mug retained its shape, so at the end of the night and after melting ~20 cans, we had a good chunk of nearly pure aluminum in a puddle under the furnace.

Aluminum-Silicon Alloys

2021-6-4 · Castings are the main use of aluminum-silicon alloys, although some sheet or wire is made for welding and brazing, and some of the piston alloys are extruded for forging stock. Often the brazing sheet has only a cladding of aluminum-silicon alloy and the core consists of some other high melting alloy. The copper-free alloys are used for low- to ...

The Best Aluminum Alloys For Welding

Classifications of Clay Types

Polymer clay is generally used for making arts and craft items, and is also used in commercial applications to make decorative parts. Art made from polymer clay can now be found in major museums. Polymer clay remains workable until cured generally from between 265 F (129 C) to 275 F (135 C) for 15-minutes per 1 ⁄ 4 -inch (6.4 mm) of thickness.

Cast vs. Wrought Aluminium

Cast aluminium alloy is produced from bauxite. This is a naturally occurring mineral containing 15-20 % aluminium and is the only ore still used for commercial aluminium extraction. The process to extract pure aluminium from bauxite is highly complex and …

Chapter 2 ALUMINIUM''S ADVANTAGES

2015-5-12 · Aluminium is the lightest of the common metals (table 3), its density of 2.7 being one third that of steel. Structures made of aluminium alloy will therefore always be lighter than their steel counterparts. In theory, aluminium and steel can be compared using three cri-teria (table 4): at equal thickness, for structu-res not subjected to stress ...
