• Brass is a metal alloy composed primarily of zinc and copper.
• Alpha brass contains less than 35% zinc.

Difficulty:Medium

The student wants to specify an advantage of alpha brass. Which choice most effectively uses information from the notes to accomplish this goal?

As a metal alloy composed primarily of zinc and copper, alpha brass has a notable advantage over beta brass.

Unlike beta brass, which requires heat to manipulate, alpha brass can be shaped at room temperature.

Alpha brass contains less than 35% zinc, whereas beta brass contains more than 45% zinc.

With its higher zinc content, alpha brass is a stronger material than beta brass.
