We wanna try something different on the LED flashlight materials - this time it is the aerospace 7075 aluminum alloy. 7075 aluminum is stronger than 6063, it is usually used for high-stress applications like Aircraft fittings, shafts, and even missile parts, etc. Besides the stronger on the material, the surface anodization is also harder and thicker, the thickness is about 65um (approx 2.5mils) which makes it performs better on scratch resistance. And the new treatment brings a new color - Military Tan and the crackles on the surface are normal. These are the difference from the Aurora A23.
