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.
The team of scientists that worked for the first time on the research of the Hydrogen Bomb would be the Aldermaston scientists. Sir William Penney was in charge of the project.

The short answer is that the hydrogen bomb -- the fusion bomb -- was the natural extension of the relatively simple fission bombs used over Japan in WWII. The very creation of the fission "atomic" bomb made possible the pressures and temperatures needed to foster a fusion reaction. Doing so promised to unleash a level of energy and power unheard of even within the circles of Los Alamos. More to the point, the Soviet Union had been conducting a crash development program to create an atomic bomb after WWII, a program that used the Soviet bomb research, but added to it all the missing pieces supplied to them by agents in the US. Spies like Klaus Fuchs and Ethel and Julius Rosenberg supplied the USSR with the design details for the basic A-bomb. In 1949, about the same time they figured out how to reverse-engineer a B-29, the Soviets detonated an atomic bomb. Having stolen secrets far beyond the mere "firecracker" of a fission A-bomb, the Soviets immediately embarked on a crash program to develop the same thing the Americans were working on -- the fusion bomb. The "hydrogen" bomb, or "thermonuclear" bomb, borrows its power and its design from our sun. The star we depend on is powered by a never-ending cycle of nuclear fusion and fission. The "hydrogen" bomb works by using the heat and energy of fission to create fusion, then the heat and energy of fusion to create fission again. It works pretty well; the numbers went from kilotons of TNT to megatons of TNT. Why was it created? It was the logical extension of the fission bomb. It was the BIGGEST bomb around. It allowed one to place the word "megaton" into one's dictionary. American megatons and Soviet megatons lubricated the Cold War. For over forty years, East faced West, megatons in holsters at hips, and not one nuclear shot was fired. (The Cuban Missile Crisis in 1962 was ugly, but in the end, it was settled diplomatically.) No shots were fired because everyone was afraid that somebody somewhere might launch a missile or fire a shot that carried a "hydrogen bomb."

It was made in 1951 and dropped for the first time in 1952.
What time was the bomb droped on hiroshima?
Time Bomb Recordings was created in 1994.
Time Bomb Recordings ended in 2012.
Hades is often referred to as Hell by modern mistake.
The Imperial Japanese Navy made its attack on Pearl Harbor on the morning of December 7, 1941. Early in the morning (Hawaii time). A Sunday.

Time Bomb was created on 1999-09-14.
A type of rotten mussel shell produced a purple colored dye. The shell was boiled and the color extracted to dye clothing.
It was planned to bomb Hiroshima at 8.15 am and the bomb was detonated at the exact time. Melted watches show they stopped at the planned time.
Time Bomb - album - was created on 2001-03-27.
