The market value of copper laser processing market could reach over 10 billion RMB

Copper has very low absorption rate to fiber laser light. But later many fiber laser manufacturers set up an isolating setting in the fiber laser structure. This innovation greatly solved the reflection problem of fiber laser on copper and created the opportunities of fiber laser being widely used in copper cutting.

Laser processing has been proved to be the most suitable and easiest way to work on metal. According to the report, metal processing accounts for over 85% of the total laser application. However,for metal processing, normal iron and steel processing accounts for the most part, for iron and steel are the widely used metal materials for sure. But for other kinds of metal like copper, aluminum and nonferrous metals, laser processing is still not very common. Copper is the basic material of many industrial products at the beginning. It features superior conductivity, excellent heat-transfer and anti-corrosive quality.And today, we are going to talk deeply about the copper material.

Laser cutting and welding of copper

Copper has been a quite expensive metal material. The common kinds of copper include pure copper, brass,red copper,etc.. There are also various shapes of copper, such as bat shape, line shape, plate shape, stripe shape, tube shape and so on. In fact, copper is also an ancient metal. In the ancient time, people already discovered the use of copper and created many copper artworks.

Copper plate, copper sheet and copper tube are the most ideal copper shape for laser cutting. However, copper is highly reflective material, so it doesn’t absorb much of the laser beam. The absorption rate is generally lower than 30%. That means nearly 70% of the laser light is reflected. This not only causes energy waste but also easily leads to the damage of the processing head, optics and the laser source. Therefore, for such a long time, laser cutting copper has been a great challenge.

CO2 laser cutter can better cut thick material and also copper. But before cutting, a layer of graphite spray or magnesium oxide should be put on the copper to avoid reflection. Copper has very low absorption rate to fiber laser light. But later many fiber laser manufacturers set up an isolating setting in the fiber laser structure. This innovation greatly solved the reflection problem of fiber laser on copper and created the opportunities of fiber laser being widely used in copper cutting. Nowadays using 3KW fiber laser to cut 10mm copper plate has become reality.

Comparing with cutting, laser welding copper is much harder. But the advent of wobble welding head makes fiber laser more suitable for copper welding. Besides, the increase and improvement of the power and the accessories of the fiber laser also provide guarantee for copper laser welding.

Wide application of copper will help increase the laser processing demand

Copper is a very good conducting material, so it has wide application in electricity, power cable, motor, switch, printed circuit board, capacitance, communication component and telecom base station. Copper also has very good heat-transfer, so it is very common in heat exchanger, refrigeration equipment, home appliance, tubing and so on. With the laser technique becoming more and more mature and more and more people using laser processing on copper, it is estimated that the copper material processing will bring the demand of laser equipment valued more than 10 billion RMB and become a new growth point in laser industry.

Recirculating laser chiller that is suitable for copper processing

S&A Teyu is a recirculating laser chiller manufacturer with 19 years of history. It designs, develops and produces the reliable chiller units which can provide effective cooling for fiber laser used in copper cutting and welding.

During laser processing on copper material, cooling must be performed on the laser head and the laser simultaneously in order to prevent the overheating problem in these key components. And S&A Teyu air cooled chiller unit featuring dual water circuit can perfectly do the cooling job.
