Add small amounts of the metals magnesium, manganese, and copper and you make a superb aluminum alloy called duralumin, which is strong enough to make airplanes. Alloys always show improvements over the main metal in one or more of their important physical properties (things like strength, ...
3. Metal alloys are mixtures of two or more metals. The graph below compares the strength and the mass of some metal alloys.Strength and Mass Key Mass EStrength Metal Alloy A B C D Which alloy is the most suitable to make a spectacle frame which is both strong and has the least mass...
Rare earth metals, a group of 17 elements encompassing 15 lanthanides along with scandium and yttrium, have long been shrouded in mystery and misconceptions. This article aims to unravel the importance of rare earth metals by delving into their definition, debunking the myth of scarcity, and explo...
Silver is another excellent example of a diamagnetic metal, similar to palladium and rhodium. Because of this property, such metals have non-magnetic functions. Silver is well-known for itsstrong electrical and thermal conductivityand bright reflectivity. When silver is heated, this metal becomes sof...
Alloys are combinations of metals, and the main reason for making alloys is to produce a stronger material. The most important alloy is steel, which is a combination of iron and carbon and is much harder than either of its two elemental components. Metallurgists create alloys of most metals,...
B. Our most common metal, steel, is an alloy. C. Alloys have been used for thousands of years. D. Modern pewter uses other metals instead of lead. E. Alloy consists of two or more metals mixed together. F. They have to remain strong at temperatures up to1000℃.G. These metals don...

Most metals are known for their durability, malleability, and exceptional strength. So, metals have served as a key element for transportation, construction, manufacturing, and various other industrial sectors. For instance, steel is an alloy basically composed of iron. ...
Why does steel not react with either strong or weak acids? Is it because it's an alloy? Explain. How do halogens (Cl_2, Br_2, I_2) react with halides (Cl^-, Br^-, I^-)? Can we explain this reactivity? Why do ionic compounds conduct electricity in an aqueous solution or when...
