18 keys remote control with infrared signal , it could be used for many audio brands , cos it has great advantages as below :
1. Light and soft , aluminum alloy materials are mostly hollow core thin-wall composite sections, which are convenient to use, reduce weight, and have high bending strength and small deformation. The density of aluminum is about one third of that of steel;
2. Good strength: the tensile strength of pure aluminum is one fifth of that of low carbon steel, but its strength will increase significantly after heat treatment and alloying strengthening;
3. Good processing performance: aluminum alloy has good extrusion performance, and secondary machining and bending processing are easier;
4. Easy to regenerate: aluminum has low melting point, simple regeneration, and no pollution during waste treatment, which is conducive to environmental protection and conforms to the sustainable development strategy
