  • Production method of aluminum alloy for sliding bearing
    Patent number: 6899844
    Abstract: A method of producing a fine TiC particle-dispersing type Al—Sn based aluminum alloy includes the steps of: preparing either Al mother-alloy or metallic raw materials of the Al alloy and a green compact, in which TiC is dispersed; melting the Al mother-alloy or the metallic raw materials of the Al alloy to form an Al alloy melt; bringing the Al alloy melt and the green compact, in which TiC is dispersed, into contact with one another, thereby dispersing the TiC in the Al-alloy melt; casting the Al alloy melt, in which TiC is dispersed, into an aluminum-alloy ingot, in which TiC is dispersed; and rolling the aluminum-alloy ingot.

  • Aluminum alloy for sliding bearing and its production method
    Patent number: 6706126
    Abstract: Aluminum alloy, which consists of from 2 to 20% by weight of Sn, from 3% by weight or less of Cu, and from 0.3 to 5% by volume of TiC particles, the balance being Al and unavoidable impurities, exhibits improved fatigue resistance at a high temperature region, while maintaining compatibility at low temperature notwithstanding improved fatigue resistance.
