20090078398 | ALUMINUM ALLOY PLATE AND HEAT EXCHANGER FORMED BY USING SAME - There are provided an aluminum alloy plate having high strength and excellent corrosion resistance even though the plate is made thinner, and a heat exchanger formed thereof. In an aluminum alloy plate having a core material and a surface material cladded on at least one side of the core material, the surface material includes 0.030-0.30% by mass of Fe, 0.40-1.9% by mass of Mn, 0.40-1.4% by mass of Si, and 2.0-5.5% by mass of Zn, the rest comprises Al and inevitably included impurities, and an area ratio of an intermetallic compound containing Al and Mn to a whole surface of the surface material is 1% or less. | 03-26-2009 |
20090130481 | PROCESS FOR PRODUCING CLAD MATERIAL AND EQUIPMENT THEREFOR - The present invention provides a method for manufacturing a clad material and the equipment for manufacturing the clad material, in which the productivity is excellent, the surface state and the flatness of the clad material can be readily controlled and the deterioration in adhesion rarely occurs in the clad material. The method for manufacturing the clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material includes: a clad material preparation process where an ingot for core material, which is manufactured by dissolving and casting a metal for core material in a core material preparation process, and an ingot for skin material, which is manufactured by dissolving and casting a metal for skin material different from the core material in their component composition, in a skin material preparation process, are prepared, respectively; a superposition process where the ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material to manufacture a superposed material; and a clad hot-rolling process where the superposed material is hot-rolled to manufacture a clad material. | 05-21-2009 |
20100101688 | ALUMINUM ALLOY BRAZING SHEET AND METHOD FOR PRODUCING THE SAME - Disclosed is an aluminum alloy brazing sheet for heat exchanger which excels in resistance to corrosion from its inside and simultaneously attains satisfactory erosion resistance and high strength. This includes a core material of an Al alloy containing predetermined amounts of Si, Mn, Cu, Mg, and Ti; a clad material of an Al alloy containing predetermined amounts of Si, Mn, and Zn, having a predetermined thickness, and lying on one side of the core material so as to constitute an inner side of a tube member of the heat exchanger; and a filler material of an Al alloy containing a predetermined amount of Si, having a predetermined thickness, and lying on the other side of the core material so as to constitute an outer side of the tube member. The crystal grain size of the core material after brazing under specific conditions is 50 μm or more but less than 300 μm in a rolling direction. | 04-29-2010 |
20100112370 | ALUMINUM ALLOY BRAZING SHEET FOR HEAT EXCHANGER - Disclosed is an aluminum alloy brazing sheet for heat exchangers, which has high strength after brazing, high corrosion resistance and excellent brazability. Specifically disclosed is an aluminum alloy brazing sheet ( | 05-06-2010 |
20110011573 | SIDE MATERIAL AND METHOD FOR PRODUCING THE SAME AND METHOD FOR PRODUCING CLAD MEMBER FOR HEAT EXCHANGER - Provided are a side member from which a clad member for heat exchanger exhibiting excellent productivity and corrosion resistance while preventing poor adhesion can be produced in production of a clad member for heat exchanger by controlling the surface state and flatness, a method for producing the side member, and a method for producing a clad member for a heat exchanger by using the side member. A side member (A) consists of a core material and one or more layers of side member (A) applied onto one side or both sides thereof and being used in a clad member for a heat exchanger, wherein a plurality of periodic forms (B) of fine groove which become arcuate toward one direction of the side member (A) is formed on the surface of the side member (A). The periodic form (B) of fine groove extends up to the outer circumferential edge of the side member (A) with a radius of curvature of 800-1500 ram and has a period (D) of 1-8 mm in the above-mentioned direction of the side member (A) and surface roughness of the side member (A) in the above-mentioned direction of 1-15 μm 10-point average roughness (Rz). | 01-20-2011 |
