With the improvement of people’s taste in decorations, the choice of several thousand-yuan solid wood doors in the home really adds a lot of color. A good horse with a good saddle and a pair of key bearing hinges with a pair of two-odd yuan is both light and shiny. It is difficult. It is difficult to identify true and false copper bearing hinges. There are many fake bearing hinges on the market nowadays, and there are several copper loops on them that look like bearing hinges. Ordinary people want to identify it only by disassembling a hinge to see if there is a bearing in it. Let me tell you a little trick. You can tell at a glance that you can open the hinge slightly to 90 degrees or less than 90 degrees. If you hold one of the hinges, the other will open or close quickly, and the hinge may be tightened or loosened. It's fake, it doesn't have a bearing inside. If it opens or closes slowly, it feels very smooth. It is light and light, which means there is a bearing inside, which is a real bearing hinge. One way to identify whether the hinge is copper is to use a magnet to test the other way is to grind a sharp corner of the hinge on the concrete floor a few times. There is no yellow at the top corners, which is fake; the top corners that are ground out are also yellow, but the hinges are lighter, and they are made of copper alloy. Finally, pay attention to the thickness of the hinge. Of course, the thicker one is better. As long as you pass these inspections, the hinge you bought must be a genuine copper ‘bearing hinge.’
