What are calorimeters typically made out of? And does the material that the calorimeter is made out of affect the specific heat capacity of the calorimeter significantly?

A "mock" calorimeter can actually be made out of any simple, insulating material (such as styrofoam). A common chemistry experiment involves creating a coffee cup calorimeter, literally making a calorimeter out of a styrofoam cup because the material acts as a good insulator. Bomb calorimeters are generally made out of metal and are surrounded by thick, insulating walls of a heavy material. Considering that bomb calorimeters are generally standardized and made similarly despite manufacturer, the material which they are made out of is not usually factored into calculations and the heat capacity is generally given.
