The material of the toy car
British scientists have shown that the quality of steel pipes is not as good as that of aluminum alloys. Most of the high-view strollers now use imported aluminum alloys as the main part of the stroller.
1. The high-grade aviation aluminum alloy is white and flawless. The frame is made of high-strength aviation aluminum alloy. After non-toxic anode surface treatment, it has higher impact resistance, scratch resistance and cold resistance coefficient.
2. Aluminum alloy greatly improves the mechanical strength and surface hardness of aluminum, and still maintains the inherent characteristics of aluminum's light weight, and its use value is greatly increased.
3. After various surface treatments of aluminum alloy, it not only has a shiny metallic luster, but also has a very smooth and dense surface, soft and gorgeous color, and has excellent performance; while the steel pipe is easy to rust and easy to break.
