Latest Patents

Yamanouchi holds a patent for a copper-based sliding alloy that exhibits excellent wear resistance and anti-seizure properties. The patent describes a unique composition where a phase of 2 to 30 wt. % lead is dispersed in the copper alloy. This lead phase contains 0.1 to 6 vol. % hard particles such as SiC, SiO₂, Si₃N₄, Al₂O₃, TiC, WC, and TiN, with an average particle size of 5 to 25 µm. The inclusion of hard particles in the lead phase significantly improves wear resistance and reduces the risk of seizure. The soft lead phase acts as a cushion, minimizing the impact on mating components while also preventing the falling-off of lead due to the presence of hard particles.
