  • Cutting-free bronze alloys
    Patent number: 6419766
    Abstract: A cutting-free bronze alloy which is substantially free of lead contains 1 to 13 wt. % of tin, not larger than 18 wt. % of zinc, 0.5 to 6 wt. % of bismuth, 0.05 to 3 wt. % of antimony, not larger than 1 wt. % of phosphorus, less than 0.4 wt. % of lead, and the balance being copper. The alloy may further contain 0.1 to 3 wt. % of nickel. When 3 to 8 wt. % of tin and 6 to 10 wt. % of zinc are present, the alloy is particularly suitable for use as a plumbing faucet and fixture. Likewise, when 8.5 to 13 wt. % of tin and not larger than 1 wt. % of zinc are present, the alloy is suitable for use as a sliding member.

  • Syncronizer ring having a spray-coated film of a wear-resistant brass material
    Patent number: 5326646
    Abstract: A synchronizer ring comprises a ring body having a sliding portion, and a directly spray-coated wear-resistant film formed on a surface of the sliding portion. The film is made of a wear-resistant brass alloy which comprises Cu, Zn and at least one element selected from the group consisting of Al, Mn, Fe, Ni, Si, Co, Cr, Ti, Nb, V, Zr and Mo. The spray-coated film exhibits good wear resistance and good bonding strength.

  • Wear-resistant copper alloys and synchronizer rings for automobiles comprising the same
    Patent number: 5288683
    Abstract: A wear-resistant copper alloy which consists essentially of 56 to 65 wt. % of Cu, 28 to 32 wt. % of Zn, 3.5 to 5.5 wt. % of Al, 0.5 to 2.0 wt. % of Fe, 1.0 to 3.0 wt. % of Ni, 0.1 to 1.0 wt. % of Nb, and 0.4 to 1.5 wt. % of Ti, provided that Ti+Nb is equal to or greater than 0.7 wt. %. The alloy includes two discrete intermetallic compounds comprising Ti-Ni-Fe-Al and Nb-Fe-Al uniformly dispersed in a microstructure preferably including at least 50 volume % beta phase and limited alpha and gamma phases. A synchronizer ring made of the copper alloy is also provided.
