New fehral GS SY

The relevance of GS SY

Lightweight and durable alloy called resistant long been sold in the industry in many countries and helped to solve difficult design problems. Its production cost is 6 times lower than that of nichrome as a consequence of the replacement of expensive Nickel at a cheaper aluminium, and iron. Of the GS mark SY make wire by extrusion, drawing or rolling. Finished products are wound onto a coil or winding down the Bay. Tape GS SY is produced by rolling or electrolysis, and then collapses into a roll.
