Hello, Aviation nerd alert, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of the pages you created, like Aerotech Alloys, may not conform to some of Wikipedia's guidelines for page creation, and may soon be deleted.
There's a page about creating articles you may want to read called Your first article. If you are stuck, and looking for help, please come to the New contributors' help page, where experienced Wikipedians can answer any queries you have! Or, you can just type {{helpme}} on this page, and someone will show up shortly to answer your questions. Here are a few other good links for newcomers:
I see that you removed the unreferenced tag and the notability tag (which was then put back by another editor).
Although your comment Google is not an aerospace industry expert. I hardly think one can use google as evidence. Otherwise, we become limited in scope to what google tracks. The aerospace community should decide may be true, for this to be an article which meets the criteria set for Wikipedia articles, you need to provide:
Citations from reliable third-party sources - the company's own website does not count as a reliable source. Examples would include material from mainstream news organizations is welcomed, particularly the high-quality end of the market, for example the Washington Post in the United States and the Times in Britain, as well as widely used conglomerates such as the Associated Press. Websites used primarily for advertising, and the company's own website (while perhaps useful as External links) are not reliable sources.
Proof of notability of the company. The general guide is If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to satisfy the inclusion criteria for a stand-alone article. In particular, may I suggest that you read the Wikipedia guidelines for the notability of Companies.
If you feel that you can provide both proof of the company's notability and provide reliable citations about the company and its products, please add these to the article.
I have nominated Aerotech Alloys, an article that you created, for deletion. I do not think that this article satisfies Wikipedia's criteria for inclusion, and have explained why at Wikipedia:Articles for deletion/Aerotech Alloys. Your opinions on the matter are welcome at that same discussion page; also, you are welcome to edit the article to address these concerns. Thank you for your time.
