Yes, copper is generally harder than mica. In a commutator, copper serves as the conductive material, while mica is used as an insulating layer. Copper's hardness allows it to effectively conduct electricity and withstand wear, while mica's softness and flexibility allow it to provide insulation without cracking. Overall, the combination of these materials optimizes the performance of the commutator in electrical applications.

Why is nickel harder than copper?
Nickel is harder than copper because it has a stronger metallic bond, which means its atoms are more tightly held together. This results in a more rigid structure and greater resistance to deformation, making nickel harder than copper. Additionally, nickel has a higher atomic mass and density compared to copper, further contributing to its hardness.
Why Is Brass Harder Than Copper?
Brass is harder than copper because it is an alloy made of copper and zinc, which gives it enhanced strength and durability compared to pure copper. The addition of zinc to copper alters its crystalline structure, making it more resistant to deformation and wear.
Will quartz scratch a peice of copper?
Yes, quartz is harder than copper on the Mohs scale, so quartz can scratch copper.
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 is the metal used in 2p coins harder than the pure copper?
The metal used in 2p coins is harder than pure copper because it is an alloy, primarily composed of copper and tin, or sometimes with other metals like zinc. This combination enhances the strength, durability, and resistance to wear and corrosion compared to pure copper, which is relatively soft and malleable. The alloying elements improve the overall mechanical properties, making the coins more suitable for circulation.
Is calcite harder than mica?
yes
What element is harder than gold but softer than copper?
Silver is harder than gold but softer than copper.
Why were the tools for the bronze age stronger than those of earlier times?
Answer: The new smelting processes made them stronger -Apex
What element does brass mimic?
Typically copper, but it is much harder than copper.
Is aluminum harder than lead or copper?
It depends on the alloy and temper of each material. Beryllium copper alloys are harder than the softest aluminum alloys, and high-strength aluminum alloys are harder than pure copper (which is quite soft). And almost every metal is harder than lead, except a few such as gold.
Which is harder-------------- copper or diamond?
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
Is quartz harder than copper?
Based on Moh's Scale of Hardness that identifies minerals, it is. Moh's Scale of HardnessTalcGypsumCalciteFluoriteApatiteOrthoclaseQuartzTopazCorundumDiamondIn this scale, 10 minerals are used as reference. These minerals are arranged from the softest (1) to the hardest (10). thxs
Can quartz scratch a copper penny?
No, quartz is harder than copper and can scratch it. However, a copper penny is typically made of a copper-zinc alloy that is harder than pure copper, so it might be more resistant to scratching by quartz but it is still possible.
Why is nickel harder than copper?
Nickel is harder than copper because it has a stronger metallic bond, which means its atoms are more tightly held together. This results in a more rigid structure and greater resistance to deformation, making nickel harder than copper. Additionally, nickel has a higher atomic mass and density compared to copper, further contributing to its hardness.
Why Is Brass Harder Than Copper?
Brass is harder than copper because it is an alloy made of copper and zinc, which gives it enhanced strength and durability compared to pure copper. The addition of zinc to copper alters its crystalline structure, making it more resistant to deformation and wear.
Is copper harder than silver?
Yeah, mainly because it has a higher boiling point than Silver.
What material is softer lead or copper?
lead, copper is a metal therefore it is harder
