It was a steel one.
It could be made of many different things, including plastics, depending on its intended usage.The two dropped on japan in WW2 each used a casing made of an aluminum alloy called Duralumin.

The USA created the first atomic bomb in New Mexico in the closing stages of World War Two. They used it to defeat Japan.
After that the weapons race began and many atomic bombs were made.
The Cold War and nuclear arms races in the late forties through the eighties was the impetus of Americans building bomb shelters. They were convinced Russia would bomb America and they could have if Kennedy had not stopped Fidel Castro and the Russians from sending over their nuclear missiles located ninety miles from the US. Most of the bomb shelters were a joke. They never could have protected the people from the radiation in the air or from the bomb explosion.
The bouncing bomb was developed in 1943 during World War II by British engineer Barnes Wallis. It was used in Operation Chastise in May 1943 by the Royal Air Force to disrupt German dams.
the explosive used was certainly black powder, casing materials are uncertain though.

Depends entirely on the bomb. There are hundreds of different type to do different things. The basic "iron bomb" is a steel casting. Some have hardened penetrators, some may be a plastic or cellulose material, etc.
Bombs were made from a steel casing filled with various explosives.

The Second World War.
Natural casing which is most common is made from pig intestines which has been flushed throughly. They also have synthetic casing though.
special chemicals
Zinc
The casing can be made of many things depending on its intended application, but in most cases its some kind of metal. Missile warheads though usually use a composite casing that ablates during reentry, preventing the warhead inside from burning up.If you were asking about the bombs dropped in ww2 on japan, their casings were made of duralumin an aluminum alloy.
