445nm diode

Looks like you can get 7W 445nm laser diode modules fairly cheaply from China now. Claim to be able to engrave stainless steel. Not sure about aluminum. Can anyone give any comments about what power and speeds are needed for engraving stainless or cutting very thin stainless with this wavelength? Will it engrave aluminum at all?

Brian,

Am also looking at 445nm laser diode heads. Have found a few that look promising. I also have a 30W Eplilog Co2 laser. Am thinking about upgrading to use a 445nm laser diode for engraving Stainless. Like to know your thoughts. Where are you located?
