The application of potassium fluoaluminate in the high impact toughness air conditioning alloy radiator

Composition proportion of aluminum alloy sheet with high impact toughness air conditioning 
High impact ductile air radiator aluminum alloy sheet, its chemical element composition and its quality percentage are: Si00.65-0.98, Mg0.59-1.22, Mn0.22-0.40, Tm0.02-0.04, sb0.11-0.56, sr0.46-0.98, b0.26-0.58, and the remaining Al. 
The characteristics of high impact ductile air radiator aluminum alloy chip 
Aluminum alloy recipe by adding strontium, boron, in guarantee under the condition of lower intensity, effectively improve the impact toughness of the aluminum alloy piece, and processing performance is good, high quality aluminum alloy films reduced in layers, peeling, bubble, the phenomenon of crack, improved the yield;
The refining effect of the invention is good, and the porosity and slag are obviously reduced. 
The application background of potassium fluoaluminate in air conditioning aluminum radiator 

Air conditioning radiator is the key component of air conditioning, the work efficiency and service life of air conditioning.

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 properties, such as tensile strength (140Rm/MPa), yield strength (100Ra2/ MPa), hardness (9-12 degrees), poor conductivity, poor thermal conductivity, poor malleability, 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).
