摘要
An alloy suitable for use as a spinner in forming glass fibers is provided. The alloy has outstanding stress rupture-life and is highly resistant to the erosion and corrosion of molten glass. The alloy is a cobalt-based alloy and further includes the following in approximate percent by weight, Carbon 0.5 to 1.0; Silicon 0.01 to 0.15; Chromium 30 to 40; Nickel 5 to 15; Tungsten (Wolfram) 4 to 7; Yttrium 0.5 to 1.5; Tantalum 2 to 5; Boron 0.005 to 0.04; Zirconium 0.1 to 0.4. The alloy typically will include the following as impurities, the amounts indicated being in percent by weight unless otherwise set forth: Aluminum 0 to 0.2%; Titanium 0 to 0.2%; Manganese 0 to 0.01%; Iron 0 to 1%; Phosphorous 0 to 0.005%; Molybdenum 0 to 0.10%; Sulfur 0 to 0.005%; Bismuth 0 to 0.5 ppm; Lead 0 to 5.0 ppm; Selenium 0 to 5.0 ppm; Silver 0 to 50 ppm; Nitrogen (N2) 0 to 150 ppm; Oxygen (O2) 0 to 50 ppm.
