In the table below, the properties of various sheet materials at the temperatures at which they are formed are given. Choose which material is suitable for the following properties and express the reason.

a) The material with the highest Limit Shrinkage Ratio in deep drawing,

b) The material that shows the most ear in deep drawing,

c) The material that shows the most uniform deformation in tensile,

d) The material that can be drawn into the deepest shape with a hemispherical stamp, ignoring material E due to its low yield strength.
