The material that has the highest electrical resistance is silver. After silver copper and gold are the materials that have the highest electrical resistance.
What is the most electrically resistant metal?
Table of Resistivity and Conductivity at 20°C
|Material||ρ (Ω•m) at 20 °C Resistivity||σ (S/m) at 20 °C Conductivity|
Which is the most resistant material?
Diamonds remain the most scratch-resistant material known to humanity. Metals like titanium are far less scratch-resistant, and even extremely hard ceramics or tungsten carbide cannot compete with diamonds in terms of hardness or scratch-resistance.
What material has lowest electrical resistance?
Silver is the best conductor of electricity which means that its electrical resistivity will be the least.
Is stainless steel a good electrical conductor?
Stainless Steel Conductivity
Stainless steel is a relatively good conductor of electricity, as are all metals.
Is Brass electrically conductive?
Brass is only 28% as conductive as copper. Some bronzes are as low as 7% as conductive as copper! Copper is the standard by which electrical materials are rated and conductivity ratings are expressed as a relative measurement to copper.
Electrical Conductivity of Materials.

What’s harder than a diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
Which is stronger graphene or diamond?
Graphene, on the other hand, is the strongest material ever recorded, more than three hundred times stronger than A36 structural steel, at 130 gigapascals, and more than forty times stronger than diamond.
Is Titanium stronger than diamond?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … The only advantage titanium has over steel is that it is a much lighter material. When compared to diamond, however, titanium does not come close in strength or hardness.
What metal is the least conductive?
The most conductive pure metal is silver. This is what makes it the metal that is used in the construction of integrated circuits and in electronics whenever a path with a very low resistance is needed. On the other hand pure mercury has the lowest conductivity.
What is the least resistant material?
Among Aluminium, Copper and silver, Silver has least specific resistance . Originally Answered: What is a low resistivity material? A material with low resistivity means it has low resistance and thus the electrons flow smoothly through the material.
Which metal is poorest conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity. Dear friend, Tungsten and Bismuth are metals which are poor conductors of electricity. Stainless Steel is a poor conductor because it has an alloy structure.
