  • Patent number: 7762479
    Abstract: The invention provides an adjustable showerhead that provides a variety of distinct discharge water patterns. The showerhead features a ceramic disk assembly that provide long-life and reliable operation to the showerhead. The showerhead includes a wand having a receiver with a discharge outlet and a depending lug. The disk assembly includes an upper ceramic disk fixedly positioned within the receiver, and has a curvilinear groove and a water inlet hole that receives water from the wand's discharge outlet. A lower ceramic disk is movably positioned within the receiver against the upper disk, and has a plurality of outlet holes arrayed along the periphery. A bushing resides within a central opening of the lower disk and operably connects the lower disk to the receiver. An outlet assembly is operably connected to the lower disk, and includes an inner faceplate with a plurality of discharge outlets, and an outer faceplate with a plurality of discharge outlets.

  • Publication number: 20100158748
    Abstract: The present invention provides a lead-free free-cutting aluminum brass alloy and its manufacturing method. The alloy comprises: 57.0˜63.0 wt % Cu, 0.3˜0.7 wt % Al, 0.1˜0.5 wt % Bi, 0.2˜0.4 wt % Sn, 0.1˜0.5 wt % Si, 0.01˜0.15 wt % P, at least two elements selected from the group of 0.01-0.15 wt % Mg, 0.0016-0.0020 wt % B, and 0.001-0.05 wt % rare earth elements and the balance being Zn and unavoidable impurities. The inventive alloy has excellent castability, weldability, cuttability and corrosion resistance. It is suitable for low pressure die casting, gravity casting, horizontal continuous casting, forging and extrusion. Its metal material cost is lower than bismuth brass. It is particularly applicable for components used in drinking water supply systems and other structural components. It is a new environmentally-friendly free-cutting aluminum brass alloy.

  • Publication number: 20100098579
    Abstract: The present invention relates to a lead-free, bismuth-free free-cutting phosphorous brass alloy and its method of manufacture. The alloy comprises: Cu; Zn; 0.59 to 1.6 wt % P; and other elements in the amount of 0.005 to 0.6 wt %, which comprise at least two elements selected from the group consisting of Al, Si, Sb, Sn, Rare earth element (RE), Ti and B, and the balance being unavoidable impurities. The phosphorous brass alloy contains a combined wt % of Cu and Zn of between 97.0 wt % and 99.5 wt %, within which the content of Zn is above 40 wt %. Considering the solid solubility of P in the matrix of copper will be decreased rapidly with the temperature decrease and form the brittle intermetallic compounds Cu3P with Cu, the present invention relies upon P to ensure excellent cuttability of the invented alloy. The invented alloy is reasonably priced, and has excellent cuttability, castability, hot and cold workability, dezincification corrosion resistance, mechanical properties and weldability.

  • Publication number: 20100080731
    Abstract: A tin-free lead-free free-cutting magnesium brass alloy comprises 56.0 to 64.0 wt % Cu, 1.05 to about 2.1 wt % Mg, 0.21 to 0.4 wt % P and other elements 0.002 to 0.9 wt % which comprise at least two elements selected from the group consisting of Al, Si, Sb, rare earth elements, Ti and B and the balance being Zn with unavoidable impurities, wherein a cutting percentage of the alloy is at least 80%. The process for producing such alloy is also proposed. The invented alloy is excellent in cuttability, castability, hot and cold workability, corrosion resistance, mechanical properties and weldability and particularly applicable in spare parts, forging and casting which need cutting and grinding process. The cost of necessary metal materials of the invented alloy is lower than lead-free free-cutting bismuth and antimony brass alloy and is equivalent to lead-contained brass alloy.
