  1. What is the primary purpose of a material callout note in the title block of a drawing?

    Answer: To specify the material from which the part must be fabricated

    The material callout in the title block tells the manufacturer exactly what material or alloy to use when fabricating the part.

  2. Aluminum alloy 6061-T6 — what does 'T6' designate?

    Answer: Solution heat-treated and artificially aged

    T6 temper means the aluminum was solution heat-treated and then artificially aged to achieve maximum strength.

  3. Which process joins two metal parts using a filler metal with a melting point above 840°F (450°C) but below the base metal melting point?

    Answer: Brazing

    Brazing uses a filler metal that melts above 840°F but below the base metal, creating a strong joint by capillary action.

  4. On a drawing, the note 'ASTM A36' refers to:

    Answer: A structural carbon steel specification

    ASTM A36 is a widely used structural carbon steel standard specifying minimum yield strength of 36 ksi.

  5. Which manufacturing process is best suited for producing complex internal shapes that cannot be machined?

    Answer: Sand casting

    Sand casting can produce complex internal cavities using sand cores placed inside the mold.

  6. What property of a material is measured by the Rockwell or Brinell test?

    Answer: Hardness

    Rockwell and Brinell tests measure hardness by pressing an indenter into the material surface and measuring the indentation depth or diameter.
