People who buy copper wires know that the price of copper electromagnetic coils is significantly higher than that of electromagnetic coils made of other materials. Generally speaking, the iron electromagnetic coil on the market is 10 yuan up and down a kilogram, aluminum electromagnetic coil is 20 yuan up and down a kilogram, stainless steel plate electromagnetic coil is 30 yuan up and down a kilogram, and copper electromagnetic coil is 60 yuan up and down a kilogram. So why are copper bolts so expensive and so many people have to pay a price to order them? You can't extricate yourself from the following aspects:

1. The copper resistor is not big, and the conductivity is very good. Therefore, it is necessary to select all aluminum core pulling rivets on some household appliances such as electric bulbs, so as not to damage the characteristics of the goods.

2. The copper bolt has shock appearance and good corrosion resistance, which can be applied to some fashionable clothes, bags, leather goods and boots.

3. Copper has good bearing capacity, strong and durable, and is easy to rivet. It has obtained very good practical effect on many commodities.

In this way, many manufacturers want to choose copper bolts with color rivets of higher quality and more suitable for their products in order to make their products more competitive. Indeed, in today's fierce market environment like the survival of the fittest among companies, if you can make the goods more competitive, it will be very worthwhile to spend more costs. Don't let the children catch the wolves. In many cases, we are just a little short of success.
