What is the elongation of the copper wire? What is the elongation unit of copper wire? What is the elongation of the copper wire? Copper wires are mainly used as conductors for wires and cables. Copper wire can also be used as winding. Since the copper wire is very soft, is the elongation of the copper wire very large? Before talking about the "elongation of copper wire", we must first know what is the elongation of copper wire. Today I will talk about the knowledge of copper wire elongation.

The elongation of red copper wire refers to the percentage of the ratio of the total gauge length δL to the original gauge length L after the red copper wire sample is stretched and broken.

What is the elongation unit of copper wire? According to the definition of copper wire elongation, we know that the unit of copper wire elongation is "%".

What is the sign of copper wire elongation? The elongation symbol of the copper wire is "δ".

What is the calculation formula of copper wire elongation? According to the definition of copper wire elongation, we know that the formula of copper wire elongation is δ=δL/L×100%.

What is the elongation of copper wire related to? The basic material of the sample is related to the size and distribution of the mesophase in the material.

What is the elongation of the copper wire? The elongation of the copper wire is still very good, and the elongation of the copper wire is between 2%-45%.

What is the difference between elongation and elongation of copper wire?

1. Different definitions:

Elongation: The ratio of the elongation of the material sample under uniaxial stretching to the original length.

Elongation: The elongation of the tensile specimen when the necking will be formed in the tensile test, that is, the elongation corresponding to the load that reaches the tensile strength.

2. The calculation formula is different:

L0 and L1 represent the gauge before and after the test.

Elongation (L1-L0)/L0*100%

Elongation rate L1/L0*100%

It can be seen from the above definition that different tensions can achieve different elongation.

Elongation is actually a specific value of elongation.
