Application
Type Cobalt #1 Wire (ERCCoCr-C) is a tubular wire version of the highest hardness standard cobalt alloy used with chromium carbides that impact outstanding abrasive wear resistance. The addition of tungsten enhances high-temperature hardness and matrix toughness for excellent adhesive and solid particle erosion wear resistance. It bonds well with all weldable steels including stainless.
