Aluminum can be gray or black gray, but no darker. The copper can not be too black, can play clear is very good. That's what makes it special. In fact, can really black aluminum is a special alumina laser marking machine it uses M6 series laser is JPT's new MOPA fiber laser, electro-optical conversion rate is high, compact size, good beam quality.
The alumina is white
Aluminum oxide white black
Alumina black beat white
Pulse width adjustable MOPA fiber laser output laser, through the high-speed scanning galvanometer system to achieve the marking function. With high and excellent laser beam, low cost, one hundred thousand hours of maintenance free, suitable for alumina black, 304 stainless steel color, black plastic white, white plastic black and other fields. Laser out of the pattern font environmental protection in line with ROHS standards.
Alumina black laser marking machine and ordinary fiber laser marking machine is not the same, this laser marking machine adopts pulse width adjustable mode, the frequency can be adjusted to up to 400Khz, can directly play the black effect of aluminum, magnesium aluminum, alumina, all kinds of aluminum are common, The small print on the back of the current Apple phone case or iPad case is made by using this alumina fiber laser marking machine.
