    Abstract: An aluminum casting alloy consisting of, by weight, of 7.0-13.0% copper, 0.4-1.2% manganese, 0.21-40% vanadium, 0.31-0.70% zirconium; impurities limited to: less than to 0.6% Si, less than 0.8% Fe, less than 0.2% zinc, less than 0.1% Mn, less than 0.2% Ni, and the remainder being essentially aluminum. There is an absence of titanium, cobalt, molybdenum, tungsten, chromium, boron, tantalum, and niobium. The alloy has, at room temperature, a UTS of about 61 ksi, a YS of about 49 ksi, a tensile elongation of about 6%, and tensile modulus elasticity of about 11.5 MSI, a compressive yield strength of about 53 ksi, a compressive modulus of elasticity of about 18 MSi; high temperature physical properties at 500.degree. F., after 1000 hours exposure to 500.degree. F., comprise a tensile strength of 33 ksi or greater, a tensile yield strength of 23 ksi or greater, a tensile elongation of about 9%, and tensile modulus of elasticity of 10 msi. The alloy is fabricated by a) squeeze casting an aluminum alloy melt of such character; (b) extracting the solidified casting from the die and heat treating the casting to dissolve all alloying elements (i.e., 995.degree.-1018.degree. F. for 7-20 hours); and (c) aging the solution treated casting to achieve improved strength characteristics (i.e., in the range of 340.degree.-400.degree. F. for 5-20 hours).

    Abstract: The present invention relates to a Cu-based sintered alloy which has a composition containing: Zn: 10-40%; Al: 0.3%-6% oxygen: 0.03-1%; any one selected, as an additional element from the group including at least one of Fe, Ni and Co: 0.1-5%, Mn: 0.1-5%, Si: 0.1-3%, and at least one of W and Mo: 0.1-3%; and the remainder including Cu and inevitable impurities. The alloy is superior in wear resistance particularly in air at temperatures ranging from the ordinary temperature to 400.degree. C., has high strength and high toughness, and further excels in the uniform temporal change characteristics with associated members, as evaluated by its friction coefficient. The invention relates also to parts for automotive equipment made of this Cu-base sintered alloy, such as synchronizer rings for transmission, valveguides for engines, bearings for turbo-chargers and so forth.

    Abstract: A round plate shape shoe for incorporation into a swash plate type compressor as an operative engaging element intervened between a rotatable swash plate and a reciprocal piston is structured to have a first flattened face slidably contacting the swash plate and a second face opposite to the first flattened face, the second face being formed with a recess for receiving a ball bearing, which has a spherical shape portion complementary with a part of the ball bearing and a round bore portion with a bottom. The spherical shape portion of the recess is concentric with the round bore portion.
