The tensile strength of aluminum is approximately what fraction of hard-drawn copper?

The tensile strength of aluminum compared to hard-drawn copper is an important characteristic to understand in materials science and engineering. Hard-drawn copper has a significantly higher tensile strength than aluminum. Specifically, hard-drawn copper typically has a tensile strength of around 210 MPa, while aluminum's tensile strength generally falls within the range of 70-150 MPa, depending on its alloy composition and condition.

When comparing these materials, it is found that the tensile strength of aluminum is approximately half that of hard-drawn copper. This ratio underscores the reason why certain applications may favor copper over aluminum despite aluminum’s advantages in terms of weight and corrosion resistance.

Understanding these properties helps in selecting the right materials for specific engineering applications, ensuring that the materials used can withstand the necessary loads and stresses without failure.
