Title: Determine the properties and characteristics of ferrous and nonferrous metals and their alloys used in an aircraft's structure.
Course: Aviation Maintenance Technology II (20114-II) > Section: Exploring Aircraft Materials and Processes

Determination should be based upon metals common to aircraft construction, including

- ferrous metals
  - iron—used to make steel
  - steel—used with alloys: carbon, sulfur, silicon, phosphorous, nickel, and chromium
- nonferrous metals
  - aluminum—copper, magnesium, manganese, and zinc
  - copper—as an alloy, used as a base to create brass, bronze, and beryllium
  - magnesium—as an alloy, combined with zinc, aluminum, thorium, zirconium, and manganese
  - nickel—combined with copper to form Monel and with chromium, iron, and others to form Inconel
  - titanium—alpha, alpha-beta, and beta alloys create compounds of various strengths

The student should also determine whether the used hardware or suspected unapproved parts (SUPS) were used.
