Description
Technical Field
The utility model relates to an aluminium alloy production field specifically is an ultra-thin type two-sided buckle aluminium alloy extrusion die.
Background
The density of the aluminum profile is only 2.7g/cm3about the density of steel, copper or brass (7.83 g/cm each)3，8.93g/cm3) 1/3 of (1/3). Aluminum can exhibit excellent corrosion resistance under most environmental conditions, including in air, water (or brine), petrochemistry, and many chemical systems. Aluminum profiles are often chosen for their excellent electrical conductivity. On a weight-equal basis, aluminum has a conductivity nearly twice that of copper. The aluminum alloy has a thermal conductivity of about 50-60% that of copper, which is advantageous for manufacturing heat exchangers, evaporators, heating appliances, cooking utensils, and cylinder heads and radiators for automobiles. The profiles are non-ferromagnetic, which is an important property for the electrical and electronic industry. Aluminum profiles are not self-flammable, which is important for applications involving handling or contact with flammable and explosive materials. The machinability of the aluminium profile is excellent. In wrought and cast aluminum alloys and in the various states that these alloys have after their production, the machining characteristics vary considerably, requiring special machines or techniques. The specific tensile strength, yield strength, ductility and corresponding work hardening rate of the aluminum profile dictate the amount of deformation allowed.
