The second Day of the semester was good and interesting. We started the day finishing notes on Ferris and non-Ferris metals. The class was on that subject for an hour and a half. We have written three pages of notes so far and I plan to write much more. After a fifteen-minute break for the day we started on the Alloys and Aluminum. There are many different materials added to metals to make them stronger or if needed weaker. A few of the metals have a high corrosion rate. That is when the companies send it to get what is called ALCLAD. This puts a thin coat on both sides of a sheet of metal. The thin coating sprayed onto the sheet of metal is one hundred percent aluminum. That is the basics of what I have learned today. Tomorrow we are learning about the labeling of hardware.
