    Abstract: A wear-resistant wrought Al alloy having a desirable high fatigue strength, toughness and flexure strength when subjected to a quenching and an age hardening heat treatment. The Al alloy contains 8.0 to 13.0% by weight of Si, 0.1 to 0.5% by weight of Fe, 1.5 to 5.0% by weight of Cu, 0.4 to 1.5% by weight of Mg, 0.05 to 0.5% by weight of Cr, 0.05 to 0.5% by weight of Ni, an element selected from the group consisting of 0.005 to 0.05% by weight of Sr and 0.05 to 0.3% by weight of Sb, and the remainder being Al and unavoidable impurities, wherein there is no more than 0.04% by weight of Mn as an unavoidable impurity. The Al alloy having Si particles being finely dispersed therein, wherein an average diameter of an equivalent circle of Si particles is not more than 5.00 .mu.m and an average roundness of Si particles is not less than 0.50. The amounts of Fe, Cr and Ni contained in the alloy and the amount of Mn as an impurity are such to prevent Si particles and other intermetallic compounds from enlarging. At the same time, with the above amounts of Sr or Sb, it is possible to reduce the size of the Si particles and to control the shape. Thus the occurrence or propagation of cracking, which is caused by Si particles can be delayed. The Al alloy exhibits the characteristics necessary for a scroll compressor.

    Abstract: An aluminum-silicon alloy having excellent mechanical characteristics is formed by pressure casting of a molten material concurrently with modifying thereof by a flux which includes at least one element selected from the group of Na, Sb, Sr, and/or Ca, allowing a substantially fine grain of silicon to be dispersed in the alloy. Alternatively, the step of the pressure casting is replacable by substantial uniform cooling of the molten material regardless of a thickness thereof by cooling a die having a mold formed of a Cu-W type material, which mold corresponds to a substantially thick portion of the alloy.

    Abstract: A hypereutectic aluminum-silicon casting alloy having a refined primary silicon particle size and a modified silicon phase in the eutectic. The aluminum base alloy includes from 19% to 30% by weight of silicon and also contains 0.005% to 0.06% by weight of phosphorus, and 0.15% to 1.15% by weight of titanium. On cooling from solution temperature, the phosphorus serves as an active nucleant for the primary silicon phase, while at a lower temperature, a titanium-aluminum intermetallic compound is formed that is sheathed by the pseudoprimary .alpha.-aluminum and the sheathed particles act as a nucleant to modify the acicular silicon phase in the eutectic. The resulting alloy has primary silicon refinement coupled with eutectic silicon modification.

The level of Sr in excess of 0.10% and Ti in excess of 0.005% is such that the alloy has a microstructure in which any primary Si formed is substantially uniformly dispersed and is substantially free of segregation, and in which substantially uniformly dispersed Sr intermetallic particles are present but are substantially free of such particles in the form of platelets, with the microstructure predominantly comprising a eutectic matrix.

    Abstract: An improved eutectic aluminum-silicon alloy having a relatively high level of bismuth is provided which is particularly wear-resistant and sufficiently self-lubricating so as to be suitable for use in a wearing component even when poorly lubricated. The relatively high bismuth level within the alloy cooperates with the other elemental additions so as to provide a sufficiently low friction bearing surface (or self-lubricity), which significantly enhances the wear resistant properties of the alloy. In addition, the preferred alloy also has relatively substantial additions of both nickel and copper, which results in the homogeneous distribution of hard wear resistant nickel and copper phases throughout. The improved aluminum alloy should minimize wear and alleviate galling during use.
