These properties are critical during production. When making reflectors, manufacturers bend the discs. High elongation lets discs curve without cracking. Tensile strength ensures they don’t break during this process. Yield strength stops the discs from staying deformed. For example, a disc bent into a parabolic shape retains its form. This is key for focusing LED light.
In use, mechanical properties matter too. Outdoor LED lamps face wind and debris. High hardness prevents scratches on the disc surface. Good wear resistance keeps reflectivity high for years. Indoor lamps like ceiling lights need less strength. But even they rely on elongation for proper shaping.
Hot-rolled
aluminum discs for LED lamp reflectors excel in these mechanical areas. They outperform other materials like steel or plastic. Steel is heavy and hard to shape. Plastic has low reflectivity. Aluminum discs balance all needed mechanical traits.
