All copper lamp manufacturers teach you how to choose all copper lamps with good value for money?
It goes without saying that the material of the all-copper lamp is mainly made of copper, which makes the all-copper lamp not rust and has a longer service life than ordinary lamps. Then, due to the complicated manufacturing process and many procedures of the all-copper lamp, copper is in short supply and the price remains high, so some manufacturers choose to use copper only locally when manufacturing all-copper lamps in order to reduce costs, which greatly reduces the quality and service life of all-copper lamps. As buyers, how can we select the full copper lamp that is really worth the money from such a wide range of full copper lamps?
First, listening to the sound, looking at the color, using electroplating technology to make imitation copper lamps is more common in the all-copper lamp industry, in other words, relatively cheap materials such as iron or zinc alloy are colored more than twice. Although the effect is very similar to that of copper, however, it can be distinguished by mastering the observation skills. After the real all-copper lamp is colored, when we observe it with our eyes, it reveals the unique metal texture of brass.
This kind of texture cannot be realized by other materials and processes.
In addition, if we make a crisp sound when we beat it with a wooden stick, it means it is copper, otherwise it is not.
Second, the surface treatment, as an all-copper lamp, whether it can be durable or not, the key lies in whether the surface treatment is in place.
In order to save costs, some manufacturers have saved pickling, blackening, polishing and other processes.
The polished material is directly colored with a color-adjusted sealing oil.
The effect is that the surface ages quickly and the sealing oil falls off quickly.
The method of discrimination is very simple. Find some places where oil is easy to accumulate at the corners and see if the color of the accumulated oil is dark red. If so, it means that the product is colored with fine color instead of the normal manufacturing process.
