Question

The ultimate tensile strength for heat-treated muntz metal is __________

(a) 80,000 p.s.i

(b) 20,000 p.s.i

(c) 60,000 p.s.i

(d) 57,000 p.s.i

This question was addressed to me in examination.

I'd like to ask this question from Properties of Copper and its Alloys-1 topic in chapter Copper and its Alloys of Aerospace Materials & Processes

Answer 1

Right option is (a) 80,000 p.s.i

To explain: Muntz is a metal consisting of both copper and zinc. It has several advantageous properties, like being corrosion-resistant under certain conditions and possessing high strength when subjected to heat treatments.
