Definitions
- a fourth aspect of the present invention provides a method of manufacturing an aluminum alloy extruded product exhibiting excellent surface properties, the method comprising: melting and casting an aluminum alloy having the above composition to obtain an ingot; subjecting the ingot to homogenization which includes a first-stage heat treatment in which the ingot is maintained at 550 to 650°C for two hours or more and a second-stage heat treatment in which the ingot is cooled to room temperature, heated to 400 to 500°C at an average temperature increase rate of 20 to 60°C/h, and maintained at that temperature for three hours or more; heating the ingot at 480 to 560°C; and extruding the ingot.
- a fifth aspect of the present invention provides a method of manufacturing a heat exchanger comprising extruding a heat exchanger multi-port tube using the above method, and joining the multi-port tube to a heat exchanger by brazing.
- Mg improves the strength of the alloy when contained in an amount of 0.2% or less. Moreover, when manufacturing an automotive heat exchanger by brazing using a fluoride-type flux containing potassium fluoroaluminate, excellent brazeability can be stably obtained. If the Mg content exceeds 0.2%, when manufacturing an automotive heat exchanger by brazing, a fluoride-type flux containing potassium fluoroaluminate which is melted during heating for brazing reacts with Mg in the material to produce compounds such as MgF 2 and KMgF 3 . This reduces the activity of the flux, whereby brazeability deteriorates. Moreover, the extrudability of the alloy decreases when the Mg content exceeds 0.2%.
- the first-stage heat treatment performed at a high temperature is effective for decomposing, granulating, or redissolving coarse crystals formed during casting/solidification.
- the first-stage heat treatment promotes dissolution of Mn and Si (solute elements) in the matrix. If the solid solubility of these solute elements in the matrix is high, the moving speed of dislocation in the matrix decreases, whereby the deformation resistance of the aluminum alloy increases. Therefore, the extrudability of the aluminum alloy decreases when the aluminum alloy is hot-extruded after homogenization including only the first-stage heat treatment.
- the second-stage heat treatment is performed at 400 to 500°C for three hours or more. If the temperature is less than 400°C, only a small amount of Al-Mn-Si intermetallic compounds precipitate, whereby the effect of decreasing the deformation resistance becomes insufficient. If the temperature exceeds 500°C, the intermetallic compounds precipitate to only a small extent, whereby the effect of decreasing the deformation resistance becomes insufficient. If the treatment time is less than three hours, since precipitation does not sufficiently proceed, the effect of decreasing the deformation resistance becomes insufficient. The reaction proceeds to a larger extent as the treatment time increases. On the other hand, a further effect cannot be obtained even if the treatment is performed for more than 24 hours. This is disadvantageous from the viewpoint of cost. The treatment time is still more preferably 5 to 15 hours.
- the temperature decrease rate from the first-stage heat treatment temperature to the second-stage heat treatment temperature (the temperature increase rate from room temperature to the second-stage heat treatment temperature when the billet is cooled to room temperature after the first-stage heat treatment) in order to precipitate Mn and Si dissolved in the matrix to decrease the solid solubility of Mn and Si and to achieve the above dispersion state of the intermetallic compounds.
- the average temperature decrease rate from the first-stage heat treatment temperature to the second-stage heat treatment temperature is 20 to 60°C/h.
- the heating temperature is less than 480°C, deformation resistance is increased due to too low a temperature, whereby the extrudability of the aluminum alloy is decreased.
- the heating temperature is still more preferably 480 to 530°C.
- the holding time at the above heating temperature is preferably 30 minutes or less. If the holding time exceeds 30 minutes, the intermetallic compounds precipitated during homogenization are redissolved to increase the solid solubility in the matrix. This results in an increase in deformation resistance during hot extrusion, whereby the extrudability of the aluminum alloy is decreased.
- the holding time is still more preferably 10 minutes or less.
- test specimens 1 to 5 according to the present invention exhibited excellent extrudability, did not show adhesion of deposit to the surface, and exhibited excellent brazeability, intergranular corrosion resistance, and strength.
- test specimens 6 to 9 and the test specimen 10 (known alloy) were inferior in at least one of extrudability, adhesion of deposit, strength, brazeability, and intergranular corrosion resistance.
- An aluminum alloy having the composition A shown in Table 1 was melted and cast by semicontinuous casting to obtain a billet.
- the resulting billet was homogenized under the conditions shown in Table 3.
- the billet was homogenized by increasing the temperature of the billet to a first-stage heat treatment temperature at an average temperature increase rate of 50°C/h, maintaining the billet at the first-stage heat treatment temperature, decreasing the temperature of the billet to a second-stage heat treatment temperature, maintaining the billet at the second-stage heat treatment temperature, and decreasing the temperature of the billet to 300°C at an average temperature decrease rate of 50°C/h.
- Table 3 shows the first-stage heat treatment temperature, the average temperature decrease rate from the first-stage heat treatment temperature to the second-stage heat treatment temperature, and the second-stage heat treatment temperature.
- the billet was hot-extruded under the conditions shown in Table 3 to obtain a multi-port tube shown in FIG. 1 .
- the resulting multi-port tube was used as a test specimen.
- the extrudability of the aluminum alloy during hot extrusion was evaluated in the same manner as in Example 1. Likewise, the number of deposit portions adhering to the surface of the extruded multi-port tube was calculated, and the gloss of the multi-port tube was observed. The distribution of intermetallic compounds precipitated and dispersed in the matrix was also determined.
- the multi-port tube was subjected to joining by brazing, and brazeability, tensile strength after heating for brazing, and intergranular corrosion susceptibility were evaluated. The results are shown in Table 4. In Tables 3 and 4, values outside the conditions according to the present invention are underlined.
- test specimens 11 to 15 homogenized under the conditions outside the conditions according to the present invention were inferior in at least one of extrudability, number of deposit portions, strength, brazeability, and intergranular corrosion resistance.
- An aluminum alloy containing 0.6% of Si, 0.2% of Fe, and 1.0% of Mn (Mn%/Si%: 1.7) was melted and cast by semicontinuous casting to obtain a billet.
- the resulting billet was homogenized under the conditions shown in Table 5.
- the billet was homogenized by increasing the temperature of the billet to a first-stage heat treatment temperature at an average temperature increase rate of 50°C/h, maintaining the billet at the first-stage heat treatment temperature, decreasing the temperature of the billet to room temperature, increasing the temperature of the billet to a second-stage heat treatment temperature, maintaining the billet at the second-stage heat treatment temperature, and decreasing the temperature of the billet to 300°C at an average temperature decrease rate of 50°C/h.
- the extrudability of the aluminum alloy during hot extrusion was evaluated in the same manner as in Example 1. Likewise, the number of deposit portions adhering to the surface of the extruded multi-port tube was calculated, and the gloss of the multi-port tube was observed. The distribution of intermetallic compounds precipitated and dispersed in the matrix was also determined.
- the multi-port tube was subjected to joining by brazing, and brazeability, tensile strength after heating for brazing, and intergranular corrosion susceptibility were evaluated. The results are shown in Table 6. In Tables 5 and 6, values outside the conditions according to the present invention are underlined.
- test specimen 16 according to the present invention exhibited excellent extrudability, did not show adhesion of deposit to the surface, and exhibited excellent brazeability, intergranular corrosion resistance, and strength.
- test specimens 17 to 21 were inferior in at least one of extrudability, adhesion of deposit, strength, brazeability, and intergranular corrosion resistance.
