craftsmanship. The selection of the correct material for a specific repair job demands familiarity with the most common physical properties of various metals. Of primary concern in aircraft maintenance are such general properties of metals and their alloys as hardness ... structural metals. Hardness refers to the ability of a material to resist abrasion, penetration, cutting action, or permanent distortion. Hardness may be increased by cold-working the metal and, in the case of steel and certain aluminum alloys, by heat…
