Brass Lock Cylinder

A brass lock cylinder is a crucial component of a lock, where the key is inserted and turned to lock or unlock the mechanism. Made primarily of brass, a durable and corrosion-resistant material, the cylinder houses a series of pins, springs, and other internal components that function together to secure the lock. 

These pins are set at varying heights, and the key's ridges match these specific heights, enabling the key to rotate the cylinder and engage or disengage the lock. Brass lock cylinders can be designed to be interchangeable, allowing for easy removal and replacement with a different cylinder to change the key system, or they can be fixed, meaning they are permanent and not interchangeable. One notable manufacturer of brass lock cylinders from China offers a range of high-quality products to meet various locking needs.
