Materials Science and Engineering are the names of whole fields. This attempts to serve an entire field as an umbrella journal, which is kind of like having a "Journal of Science". The topic is really broad and it's hard to see such a journal as viable.
The journal's website looks very unconvincing. It says there's a journal A and journal B is because it's been separated into two issues, which doesn't make sense. The list of editorial board members is also very strange, since it gives the country of the editor as opposed to institution, and the journal apparently doesn't have an editor-in-chief.
I'd avoid the publisher, especially if they're expecting you to pay for publication (if they're inviting you to submit, I would expect cheaper or maybe even free open access). You could try emailing some of the editorial board members to confirm.
