Aluminum would be best if the gantry travels, since weight is a factor. If it's a fixed gantry "bridge" design with a moving table, then cast iron would be fine.

Thank you for your answer,
The machine is 2000mm x 3000mm cnc router with moving gantry.
I understand what you are saying and i agree with this.
The only thing i am afraid is the distortion of the gantry in the futture as Aluminum is soft material, well softer than cast iron.
I am afraid that it is going to skew in the future although the manufacturer guarantes that it would work fine without any distortions.
What about the other specifications ?
Do you think that they are good for a cnc router ?
Best Regards

Some aluminum is soft, but heat-treated alloys of aluminum shouldn't distort in normal use as a gantry. The specifications seem basically alright to me, except for the typos "Yaskava?" and stuff like "*mmg*U00*" (whatever that is) but some suppliers routinely lie about things like "accuracy", "delicacy" and the actual working power of a spindle. It might require a type of electricity that's not available to you. The software included might work, or it might have bugs, malware, or be a pirated copy that can't be registered or updated. Support may be good, poor, or non-existent. Before sending your money off to China, you'd be well-advised to check here and elsewhere on the internet for reports from others who have done so, and see how they fared. If you can't find anything about this particular company, then it could be a scam - many of the things sold on the internet for high prices turn out to be nothing but pictures and specifications borrowed from someone else, and someone who wants you to send them money by wire, for products that never show up.

I will order that machine from Alibaba site.
They have verified the supplier and they give as i know a waranty about it.
You are true though.Until i get the machine i would never be sure...
Yaskawa by the way is Japanese Servo motors
The spindle is 4.5W Italian.
I already have an old Mecanumeric MF1525 cnc router which works for 15 years now without ANY problem.
My budget is very limited now , that is why i am looking for a chinese cnc for my second shop.
I just hope(yes hope) that my money would not go on the garbage...
