Is silver heavier than steel?
Yes, Steel is a harder metal than Silver. :)
Explain why iron was replaced by steel in ship construction?
Steel is stronger and more flexible than iron.
Is a diamond stronger than steel?
Yes. Actually... a diamond is NOT 'stronger' than steel. A diamond is 'harder' than steel, but it is not stronger.
Why do we not use rubber in young modulus experiment of elasticity?
Contrary to popular expectation, rubber is not really elastic, atleast not the way scientists define elasticity. Rubber is actually much less elastic than steel. Thus for best results we use steel or similar materials, say brass, in this experiment.
Why do liquids expand on heating more than solids?
The answer is a lot more simple than you may imagine, it is simply because the atoms and molecules in liquids havd more freedom to move about than in solids
Is brass heavier than steel?
No, steel is generally heavier than brass. Steel is an alloy of iron and carbon with a density greater than that of brass, which is an alloy of copper and zinc.
Does cast iron expand more than steel?
NO.
Do brass or steel hinges last longer?
Brass hinges last longer than steel hinges.
Is copper cheaper than stainless steel?
Yes, brass is cheaper than copper.
Would brass or iron expand in a bimetallic strip?
Brass and iron have different coefficients of thermal expansion, so when exposed to a change in temperature, they would expand by different amounts. This difference in expansion causes the bimetallic strip to bend due to the unequal expansion of the two metals.
Is steel rod stronger in torsion v than brass rod?
Yes
What is harder brass or bronze?
Brass is harder than bronze because it contains a higher percentage of zinc which gives it a harder and more durable quality. Bronze, on the other hand, is softer and more malleable due to its higher copper content.
What expands quicker aluminium or aluminium bronze?
Aluminium bronze expands at a quicker rate than aluminium due to its higher thermal expansion coefficient. Aluminium bronze is a copper-based alloy that contains aluminium, which makes it expand more with heat compared to pure aluminium.
In a steel pipe fitted with brass tap which metal will get corroded?
In this scenario, the steel pipe will likely corrode faster than the brass tap due to galvanic corrosion. When dissimilar metals are in contact in the presence of an electrolyte (such as water), an electrochemical reaction occurs, causing the steel to degrade. To prevent this, it's important to use proper corrosion inhibitors or coatings to protect the steel pipe.
explain why a metal bar made up of two strips, one of steel and another of brass bend when heated?
An example; if the metal bar, made up of 2 steel and brass strips, is heated the strips will also heat up. Each material’s coefficient of thermal expansion varies, which indicates how much a material is affected by heat. :Steel has lesser coefficient of thermal expansion than brass. While warming the bar, the brass strip elongates more than the steel strip because of a higher coefficient of its thermal expansion. When the two strips are attached one next to another, the expansion at the two ends differs and this bends the bar. The brass strip expands more than the steel strip will hence exert force on the steel strip and expands it outwards. This creates a bend in the bar, the brass strip moves out more than the steel strip as shown in Fig. When the bar will be cold, strips will also contract and bar will go back to the first position and so on. However, heating and bending the bar can cause significant stresses in the material including deformations that can lead to prolonged changes within the properties of the material and failure over time.
In a corrosive environment where a conductive metal is required is brass or stainless steel better?
Brass has better conduction than stainless steel. being roughly 65 percent copper which is one of the best conductors (thermal and electrical)
Why are firearm cartridges made from brass?
Not all firearm cartridges are. Some casings are made from steel or aluminum. Brass is used because it is a soft metal, and established a tight seating and seal in the chamber. Additionally, soft metals such as brass put less wear on chambers and extractors than aluminum or steel. Brass is also desirable for those who handload, since brass casings can be used for reloading.
