| 简介 |
The present invention refers to weight circuit turns on/consisting (Al-Si-Cr) aluminum alloy outdoor easy in a single process and consequently being an ad channel relates to the production of, aluminum alloy reads details (Al-Si-Cr) 450-600 ° C of a metal melting furnace paste has better mouth feeling and, at a temperature in the range 6-12 by heating at a time and that the; metal melting furnace may be melted in keeping warm body in aluminum for casting rare earth alloy, at a temperature in the range 350-500 ° C after preheating and hot extrusion (or rolling); hot extrusion (or rolling) extruded material generated in the a (or rolled material) is possible a corrosion and a transformation to be cold rolled, 450-530 ° C same and curved while a 8-12 at room temperature; heat treated aluminum surface of panel pre-processing of a is carried out to increase the obtained from the same aluminum alloy characterized by an ad channel of consisting (Al-Si-Cr) relates to manufacturing method. |
