Member having spring properties and product employing same

摘要

In a member having spring properties, such as a slider for a slide fastener or a snap button, the member main unit is composed of copper or a copper-based alloy, and the spring member attached to the member main unit is also composed of copper or a copper-based alloy. This eliminates the trouble of having to separate the structural components when recycling copper and also allows regenerated ingots to be readily prepared through a remelting process, thereby lowering recycling costs.
