Explain the hot work features of 60/40 based on copper-zinc equilibrium diagram

1. It is frequently used for castings and is particularly suitable for die casting

2. In a+b phase characterized by hard and tough and slightly elastic

3. In phase a+b' has a hard and ductile nature of the higher

4. Applications: hot forgings,heat exchanger, condenser plates and etc.

5. Then annealed at about 450 degree celcius to convert the microstructure to a single phase of better resistance to corrosion by dezincification in aggressive supply waters

6. Also known as the brass Muntz

7. Structure in the phase a+b and a+b'

8. suitable for hot work process like hot drawing,press work and hot rolling.

9. While most brasses are not normally ranked as 'heat treatable',some brasses of very closely controlled composition are cast or hot worked in the duplex a/b state
