Application of potassium fluoaluminate flux in high impact toughness air conditioning aluminum alloy radiator.

Air conditioning radiator is the key component of air conditioning, it is related to the efficiency of air conditioning and service life.
And as household air conditioning miniaturization and lower the manufacturing cost, air-conditioning foil fin thickness is more and more thin, in the direction of the thinned, hard, and high precision development, requires a new alloys, new processing technology and quality level.
The processing precision of air - conditioner foil fin is high, and the aluminum foil has good plasticity and high strength.
At present, the aluminum foil of air conditioning radiator mainly has poor mechanical performance, such as tensile strength (140Rm/MPa), yield strength (100Ra2/MPa), hardness (9-12 degrees), poor conductivity, poor thermal conductivity, poor plasticity, etc.

High specification aluminum heat sink is focused on ingredients and melting, the temperature between 750-760, try to control the melt in the temperature range without the introduction of impurity mineral melting agent only fluoride potassium aluminate (usually also have the habit called elpasolite).
