Explanation:
It is because tungsten has a very high melting point. If tungsten is used as a fuse wire, it will not melt if the current goes beyond 15A, and it will fail to safeguard appliances like refrigerator, AC etc. which will eventually cause damage to the appliances and other circuit elements.
