Conventional tungsten carbide wires used in wire matrix printers are extremely hard but very brittle and thus susceptible to fracturing. The figure shows a cross-section of a new wire which consists of a core made from a relatively ductile material encased with tungsten carbide. The core may consist of a tungsten filament having a size between .001 and .004 inch in diameter. The case will vary in size to yield a total diameter of .011 to .014 inch.
