Hi I found a 600v 50a mosfet, for less than 65 cents. Its Rds is less then 160milliohm. Can I use for the zvs circuit. I checked the datasheet, and the switching times are pretty similar to irfp250, but it has a higher gate capacitance. I am trying to run a ZVS circuit with an arc welder, since it can output a lot of current, but the open voltage is 60-70v, but it decreases under load. So I want my circuit to be able to handle 70v max.

Without a full part number, there is no way to find specifications for "50n60".  However, I suspect you will have trouble with on-resistance at higher current.  Forward voltage drop will be too high to keep the opposite FET off.
