The main lock body of smart lock is usually made from high qualtiy stainless steel materials, which make the smart lock sturdy and durable.
The lock panel of the smart lock usually adopts zinc alloy, aluminum alloy or other high-strength alloys, such as stainless steel, and then the lock panel is formed by integrated die-casting molding.
Zinc alloy is the most commonly used material because of its moderate hardness and great processability, so it can be directly shaped by die-casting without added machining processes and high processing cost.
Besides, because the zinc alloy is very easy to be polished and plated, the final surface effect is great for giving our whole smart lock a better metal texture.
Comparing to zinc alloy and aluminum alloy, stainless steel has better hardness and rigidity, but its processing and surface treatment is also more difficult. At the same time, its price is higher.
The greatest strength of aluminum alloy is its lighter quality, it is almost half the weight of zinc alloy. Although electroplating, color matching or some other processing methods are more difficult, the surface treatment is finished by anodic oxidation method, it can also prevent aluminum alloy from corrosion and color fading.
