Abstract: A metal product includes a metal substrate, at least one first hole, at least one second hole, and at least one third hole. The first hole is formed in a surface of the metal substrate. The second hole is formed in at least one of a portion of the surface of the metal substrate without the first hole and an inner surface defining the first hole. The third hole is formed in at least one of a portion of the surface of the metal substrate without the first hole and without the second hole, a portion of the inner surface defining the first hole without the second hole, and an inner surface defining the second hole. The first, second, and third holes enhance a bonding strength between the metal product and a material product. The disclosure also provides a metal composite and a method for manufacturing the metal product.

Abstract: A super-thin hanging clock includes a housing, a transparent cover, and a core that has a first shell, a second shell fitted with the first shell and having a swingable lid to hide the battery and a through hole for the button to pass through, a stator, a PC board with a control circuit, an electrically time-adjusting button, an electronic battery and a transmitting gear system consisting of a rotor, a transmitting gear, a minute gear, a front hour gear and an hour gear, whereby a coil of the stator is powered to rotate the rotor to rotate the transmitting gear provided with a toothed shaft engaging the minute gear provided with a toothed shaft engaging the front hour gear provided with a toothed shaft engaging the hour gear provided with a shaft connected to a shaft of a needle unit, thus making up the super-thin hanging clock.
