Why Are Cheaper Copper Terminal Blocks Potentially Riskier?

Low-priced copper terminal block copper alloys often use cheaper copper alloys or thin-walled designs, whose conductivity and heat resistance cannot compare to high-quality pure copper. Adding too many other metals to the copper alloy can reduce the material's conductivity, resulting in higher resistance during long-term operation, leading to localized overheating or poor contact.

Simplifying the copper distribution block manufacturing process and lowering material standards can also lead to some hidden dangers that are not easily detected. For example, imprecise molding or welding processes can lead to internal stress and uneven contact surfaces, increasing the probability of issues under actual current-carrying conditions.

Low prices often come with weaker insulation and housing materials. Under conditions of increased ambient temperature or vibration, these copper terminal strip copper alloys are more prone to issues such as cracking of plastic components and loosening of screws, affecting connection stability.
