Black hard anodizing is a post-treatment process in die casting. All aluminum materials can be color anodized, but if you choose black hard anodizing, the die cast light fixtures used will stay corrosion free and won’t discolor easily. Most aluminum reflectors can be prototyped and be made as short-run parts without the need for hard tooling. Besides that, there are numerous benefits to using the anodized aluminum for light fixtures and three of them are explained below.
Conventionally Used Material
As for lighting segment, the reflectors made from aluminum will hold the optical shape and maintain the performance of the light fixture over an array of environmental conditions. As the light fixtures will be used indoors and outdoors, the choice and quality of the dye and the seal will influence the choice of colors in anodizing. Anodized aluminum tends to have a useful lifespan as the material hold up well to UV, cold, heat, and even salt spray. The material can be cleaned by using standard cleaning methods with traditional cleaning products.
Convenience for Surface Finishes
As of now, there are wide arrays of finishes available for anodized aluminum. The options range from spectacular finishes to matte-finishes or asymmetrical choices, which will overcome the hurdles in prototyping. Aluminum parts can be interchanged by swapping one material finish for another without having to need process changes. You can have distinct versions of the reflector as per the given optical situation like the distinct distribution requirements or light sources. It is plausible to change the reflector performance and look of light fixtures by varying the surface finishes as per the usage.
Tolerance to Temperatures and Heat Dissipation
While there are a few coatings on some versions of aluminum, which have temperature limits, the upper temperatures at which the reflective properties will start to fail are in the 510 Degree Celsius range. As a material, the aluminum has high heat conductivity and dissipates the heat effectively. That is why, when it comes to withstanding heat and cold, anodized aluminum materials are used for die cast light fixtures.
In addition, aluminum will not emit the smoke, as well as will meet the building codes for fire and smoke prevention. The recyclable material is used in many applications including lightings and fixtures.
