The reserve of Rhenium is rarely in the earth's crust, it usually associates with molybdenum and copper, also in uranium ores. By 1930,the world's total output of Rhenium was only 3 gram. Even till now, the annual output of Rhenium is only about dozens of tons which is much less than the other metals.
