topas H.E.A.T. was originally developed by bedra for Makino machines with a H.E.A.T. generator but has since proven itself to be highly suitable on a variety of EDM machines.

It's ideal for substantial productivity improvements and increases in cutting speeds with applications that feature tall or stepped workpieces as well as with poor flushing conditions. It also performs extremely well in nickel alloy and aerospace applications as it dramatically increases cutting speeds and decreases cycle times.

It is manufactured in Germany by bedra and sold exclusively by SST Consumables.
topas H.E.A.T. EDM wire features a CuZn20 (80% copper, 20% zinc) core with a zinc-rich brass double-layer coating. The high copper content of the brass core provides the benefits of highly efficient energy transfer which allows for higher cutting power and speed. The zinc enriched, patented double-layer coating promotes efficient cutting and its porous nature assists in flushing which helps prevent wire breaks.

It is manufactured to a tensile strength of 800 N/mm² and features a minimum elongation of 1%. It comes in .010"/0.25mm and .012"/0.30mm diameter on a wide variety of spools.
