How to Solve Bubble Problem of Precision Light Pipe
Heat strengthened, high impact toughness, may not be sensitive to lack. Excellent thermoplastic, high speed extrusion into a complex structure, thin-walled, hollow profiles of various, or forgings forged into complex structures. Quenching temperature range, low quench sensitivity, after extrusion and forging release, as long as the temperature is higher than the quenching temperature, you can use water or through water quenching method. Thin-walled parts can also carry out air quenching. Weldability and excellent corrosion resistance, no stress corrosion cracking tendency, in the heat treatment can be reinforced in aluminum alloy, Al-Mg-Si based alloy is not the only stress corrosion cracking was found alloy. Processed surface is very smooth and easy to anodizing and coloring. The disadvantage is that after quenching, if parked for some time at room temperature in an adverse impact on aging (parked effect) have strength. From the draw method casting characteristics and thermodynamic principle is difficult to avoid hydrogen absorption (high temperature water vapor into hydrogen and oxygen in the air), although various professional manufacturers are best efforts to eliminate aluminum liquid hydrogen storage, but it is very difficult to contain the amount of hydrogen is less than the high-end technical requirements 0.15cc / 100g of. Further, since the extrusion method is cold extrusion, and the pressure is relatively small, no exhaust and other processes, precision bright tubes easily lead to the bubble problem.
