What else can I help you with?
Which is harder Aluminium or Titanium?
Titanium is generally harder and stronger than aluminum. It has a higher strength-to-weight ratio and is more resistant to corrosion and extreme temperatures compared to aluminum. This makes titanium more suitable for applications requiring high strength and durability.
Why aluminum has high thermal expansion coefficient than Copper?
Aluminum has a higher thermal expansion coefficient than copper because its crystal structure allows for larger atomic movements when heated. This results in a greater expansion of aluminum compared to copper when exposed to heat. Additionally, aluminum has a lower density and stronger interatomic bonds, leading to a higher degree of expansion when heated.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
Adding copper or magnesium to aluminum creates an alloy that is?
stronger and more durable than pure aluminum, with improved properties such as increased strength and hardness. This type of alloy is commonly used in applications that require high strength-to-weight ratio, such as in aerospace and automotive industries.
Why copper cable better than aluminium cable?
Copper cable doesn't conduct as well as Aluminum , but for most applications, Copper doesn't heat up as quickly as Aluminum, and is stronger in tensile strength. Also when using Aluminum cable you need to use an oxide to help conduct as Aluminum will work loose from locks in time.
What does adding copper to aluminum create?
Adding copper to aluminum creates a material with improved strength and corrosion resistance. This alloy is known as aluminum-copper alloy and is commonly used in automotive and aerospace applications for its enhanced properties.
Is graphite stronger than aluminum?
No, graphite is not stronger than aluminum. Aluminum is a metal known for its strength and durability, while graphite is a form of carbon known for its lightness and lubricating properties.
Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
Why aluminum reacts so slowly with copper sulphate?
Aluminum reacts slowly with copper sulfate because aluminum is more reactive than copper. When aluminum reacts with copper sulfate, it forms aluminum sulfate and copper. This reaction can be slow because a layer of aluminum oxide may form on the surface of the aluminum, inhibiting further reaction.
Compare conductivity of iron copper and aluminum in terms of electricity.?
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
Is aluminum more conductive than copper?
Copper. Alloys of copper are used in most of the electrical wiring indoors and/or outdoors.However, aluminum is used in long-distance high-tension electrical lines because by weight it's a better conductor than copper is (and because it's less expensive and stronger). An aluminum wire needs to be thicker than a copper wire in order to have the same current-carrying capacity. However, even though it's thicker, it weighs less, which means the relatively expensive transmission towers can be spaced further apart without the wire sagging too much.
