Because brass is an alloy of copper and zinc, the specific heat (calories
to change the temperature of one gram of substance one degree Celsius)
will vary with the composition of the alloy.

My Handbook of Chemistry and Physics 36th ed (1954! which shows when I
was in college!) says (p.2102)

Brass 60 Cu 40 Zn
 between -70 and +18 degr., spec. ht. = .0873
          20     100                    .0917
Brass 72 Cu 28 Zn
          14      98                    .094
