Danghyuk300 Pcs Metal Business Cards Black Metal Business Card Blanks for CNC Engraver Laser Engraving Reliable and Sturdy Multipurpose Aluminium Business Card Blanks Thickness 0.01 Inch

The media could not be loaded. In setting up and calibrating my new Commarker B4 30 watt Fiber Laser, these black aluminum business cards were just the ticket.... The quality and quantity of these cards made for multiple burn tests that helped dial in my burn settings. The attached jpg shows the results where I burned the ENTIRE Gettysburg Address on one card.... Even smaller text came out great. The video shows the burn process that took ONLY about 8 seconds or so and realizing the minuscule mirror movements that directed the laser beam to very accurately burn the text still blows me away. I know how all this $-it works and I am amazed at the speed and precision my B4 cranks out burning projects.... These cards will be my go-to business cards when I may burn through - joke :-) the three hundred I bought with my first order.... With the good quality and Great price, Illll Beee Baaaack....

These cards are awesome, really thin but flexible. They also have good memory! (when you bend them they return to the original shape. **disclaimer** probably not true for folding or creasing.)I was able to laser etch these with my 5w diode laser which is awesome as I had concerns that it would not do the job. Overall pretty awesome product for the price!

These are nice cards for diode lasers work. I have a 30 watt Lasermatic. I did have to run them at around 2800 mm/min at 40% to get a decent engrave without warping or projecting to the back. Definitely use air assist to keep them as cool as possible. I wiped them with some mineral spirits to really bring out the images. These are a bit thinner than I would have liked but work great for an impressive business card and you can't beat the price.

Will definitely be buying more. The thickness is just right, the color is perfect, the functionality is great, and great value for the money.

Super durable coating does not come off unless you want it to

A-1 Quality Would buy from again.

These looked cool in the listing, but they turned out to be way thinner than I expected. I was hoping for something that felt sturdy and premium, but they feel pretty cheap in hand.They’ll probably still work fine for certain uses, but if you're looking to make a strong first impression or something that feels high-end, these might not be it. Decent for the price, but not quite what I was hoping for.

Bought these for my son to engrave some business cards for a friend and they turned out great
