When I get it in my hand and weigh it, I obviously feel that the lock of pure copper is obviously heavy, while the lock of stainless steel is lighter. Copper is not easy to be hollow, and stainless steel can be hollow because of its strong plasticity. In terms of listening to its sound, when the door lock is opened, the copper door lock is mostly solid, so its sound is not dull, while the stainless steel door lock sounds crisp.
