Chapter 8, Problem 8.30P

Interpretation Introduction

Interpretation:

The final properties of the Cu- $30\%$ Zn brass bar under given conditions should be determined.

Concept Introduction:

Brass is used to determine the various electrical and mechanical properties. This is an alloy of copper and zinc addition. Bronze is an alloy of copper and tin instead of zinc.

Brass is generally used for low friction mechanism like as in locks, gears, bearings, casing and in valves. In electroical and plumbing operations, brass isalso used.

Brass is having high molability as compared to Zinc or Bronze.

The melting point of brass : $\left(\text{900 - 940}\right)°\text{C}$

The desnity of brass : $\left(\text{8}\text{.4 - 8}\text{.73}\right)\text{gm/cm³}$

If the proportions of zinc and copper are varied in alloy composition then the properties of brass alloy also gets chaged. Because of varing chemical composition, soft and hard brass alloys are getting formed.
