Tilak,
It won't be recoomended to use your PCB track as FUSE, as if the extra
current wil flow through this current the track may blow off,and may
be some other tracks too will blow off jus beacause of this.

If the fuse you are looking for 6A,you will get very small fuses in
Tyco.Have a look into that one.Also if you can let us know in what
application you want to put this fuse? ppl can suggest you the better
option.

Thanks
Mahesh
