ABSTRACT:
Cobalt based alloys which include chromium, nickel, tungsten, tantalum, zirconium, carbon and boron are provided which are suitable for forming spinners to be used in forming glass fibers. The alloys contain critically important amounts of carbon which maximizes the stress rupture life of the spinner alloy and minimizes the creep rate thereby making the alloy outstandingly adapted for glass manufacture.
