1. When buying a lock core, many people judge the quality of the lock core by the number of key teeth, mainly by the structure of the lock core. Generally speaking, the blade side column structure is better than the traditional marble structure. If you don't know how to choose, you can also ask a professional master to help you choose.
2. Secondly, you can also look at the "teeth" of the key. This is the simplest way to distinguish. The more complex the key structure arrangement and the deeper the tooth mark, the better its anti-theft effect.
3. To distinguish the quality of the anti-theft door lock core, you also have to look at the color and workmanship of the anti-theft door lock core. Usually, good quality lock cores are electroplated, with a smooth surface and bright color. The lock core also has different materials. The dark yellow color is the copper core, the surface is solid, and the anti-theft performance is good. If the lock core is dull in color and has bubbles on the surface, it is zinc alloy, and the anti-theft performance is average.
4. In addition to the previous identification methods, we can also half-insert the key into the lock core and press the key into the lock with 5-7 points of force. If the key gets stuck during this process, it means that the anti-theft performance of the lock core is poor.
The lock core materials include plastic, aluminum alloy, zinc alloy, pure copper and stainless steel.
The lock core materials are diverse, each with its own advantages and disadvantages. Plastic lock cores are low-cost but not durable; aluminum alloy and zinc alloy lock cores are relatively cheap, but not as durable as copper and stainless steel; copper lock cores are favored for their good mechanical properties, corrosion resistance and processing properties; stainless steel lock cores are known for their high strength and corrosion resistance, but the cost is higher. When choosing a lock core, you should consider different material options based on actual needs and budget.
