The Introduction of Flat Aluminum brazing ringsThe Flat Aluminum brazing rings is an aluminum-silicon alloy welding material with a rectangular (non-circular) wire cross-section. The Flat Aluminum brazing rings is assembled on the aluminum tube for surface contact welding, the heat conduction is more direct, and the heating is more efficient, so the welding time is shorter and the welding quality is better....
1.The Introduction of 4A11 aluminum sheet Coil block bar
4A11 aluminum sheet Coil block bar is Al-Cu-Mg-Si series alloy, a typical of 4000 series aluminum alloy,it is transformed from the former Soviet Union AK9 alloy,it has malleable, castable, small thermal expansion coefficient, thermal strength and good anti-wear performance etc advantages. In addition, it also has good mechanical properties, physical properties, corrosion resistance and better processing properties,it is a type of aluminum alloy with a wide range of uses. It is mainly used for processing forgings and blanks, for the manufacture of pistons and cylinders, and other parts that work at high temperatures,it is widely used in the field of rail transit.
