The choice of bushing material has a big impact on reliability, performance, and maintenance cost. Two common materials used in demanding industrial systems are tungsten carbide and bronze. Both are strong and proven, but their performance characteristics differ greatly. This article compares tungsten carbide vs bronze bushings, explaining where each one performs best, how long they last, and what factors affect your final choice.
