Some examples of malleable materials are gold, silver, iron, aluminum, copper and tin. While not all objects are malleable, most metals are. Their ease and flexibility when in comes to shaping are the reason they are so widely used to make jewelry and electronic circuits.Continue Reading
Malleability is a physical property of metals that defines the ability to be hammered, pressed or rolled into thin sheets without breaking or tearing. It is the property of a metal to deform under compression.
Physical changes in metal are responsible for its deformation. When a malleable metal is compressed, the individual molecules within the metal are displaced but not separated. This property allows metal to retain its composition and not break under stress. Therefore, malleable materials can be stretched, reshaped, pounded, rolled and forged into a wide variety of tools and devices. Malleable objects can usually be reshaped and molded around other objects when the appropriate amount of pressure is applied via hammer or roller.
Malleability has many applications that range from scientific to every day use. For example, malleable metals are used in almost every automobile component, especially engine components. They are also used in kitchen appliances such as refrigerators, microwaves and stoves.Learn more about Chemistry
Bronze is an alloy made of 88 percent copper and 12 percent tin. Other metals, such as aluminum, zinc, lead and silicon, are added to it frequently. It is malleable, ductile, lustrous, hard, golden brown in color, and a good conductor of heat and electricity.Full Answer >
According to the Mohs hardness scale, a list of soft metals includes lead, gold, silver, tin, zinc, aluminum, thorium, copper, brass and bronze. Gallium might also be considered a soft metal, as it melts at 85.57 degrees Fahrenheit. Mercury is a metal that's liquid at room temperature.Full Answer >
Metals such as aluminum, iron, copper, brass, bronze, steel, tin and numerous precious metals are recyclable. Metals unfit for recycling include mercury, lead and radioactive materials such as plutonium or uranium.Full Answer >
Adding aluminum to copper sulfate in the presence of water results in the following redox reaction: 2Al(s) + 3Cu2+ (aq) = 2Al3+ (aq) + 3Cu(s). This reaction forms aluminum chloride and elemental copper.Full Answer >
