Alloy dog ​​buckle's hypoallergenic treatment has formed a complete technology chain of "material optimization - electroplating upgrade - passivation strengthening - coating protection".

The rust resistance of alloy handles in humid environments is a protective system built upon material selection, surface treatment, environmental control, and usage and maintenance.

Pre-compression or pre-stretching treatment can introduce initial deformation before spring installation, and adjust the elastic coefficient through material plasticity to better meet actual usage requirements.

By adding tungsten alloy counterweights to the front or rear of the handle, the center of gravity can be adjusted, making operation more stable.

The combined application of different surface treatment processes can further enrich the gloss performance of alloy dog ​​buckle.

The effects of low temperatures on the performance of alloy handles are multi-dimensional, including challenges such as decreased toughness and stress concentration, as well as opportunities for strengthening specific alloys.
