Voice coil material- 3003-H18 for aluminum(ASV)

Aluminum is a light metal with high rigidity, light weight, and resistance to oxidation. Aluminum is commonly used as the voice coil framework in Hi-Fi and Hi-end loudspeakers.(1) Light weight and good rigidity.(2) The inner surface is flat and smooth.Light weight and good rigidity: When the speaker emits sound, the electromagnetic force generated by the voice coil drives the voice coil to vibrate together with the voice basin. The lighter the skeleton of the voice coil, the lighter the total weight of the vibration system, the higher the efficiency of the speaker, and the more transparent the sound. The lightweight speaker can effectively improve the efficiency and sound quality of your speaker. The speaker vibrates and emits sound by pushing the diaphragm (sound basin) through the voice coil skeleton, so it is required that the voice coil skeleton has sufficient rigidity to ensure that your speaker still emits a Hi-Fi sound in a high-power and large kinetic energy range.The inner surface is flat and smooth: The magnetic gap space of the speaker is very small, and when the voice coil is placed in it, any small deformation or burrs of the voice coil skeleton can collide with the magnetic circuit components, causing abnormal sound. The aluminum voice coil framework is finely cut, smooth, and burr-free, making the sound quality of your speakers absolutely pure.

Temperature resistance of 150-300 degrees Celsius
