Aluminum Vs. Cast Aluminum Light Fixtures


Aluminum, the third most abundant element and a metal that is used in everyday life, is used to manufacture numerous products, such as cans, kitchen utensils and light fixtures. Light fixtures can be made from either regular or cast aluminum.


  • Aluminum light fixtures are lightweight, nonmagnetic and nontoxic. The metal's properties make it easy to mold and resistant to corrosion. Aluminum lighting fixtures are used in medical offices, retail environments, residential settings and parking garages.

Cast Aluminum

  • Cast-aluminum fixtures are lightweight, nontoxic, nonmagnetic, corrosion-resistant and easy to mold. Due to its manufacturing process, cast aluminum is superior to regular aluminum in those properties. Die-cast aluminum is made by injecting molten aluminum, under high pressure, into a hardened steel die. Cast-aluminum fixtures gain a "greater amount of light and heat," according to website Kinetic Die Casting Blog.


  • Aluminum is nontoxic, but you may become ill if you regularly work around high levels of the metal. Persons with preexisting kidney problems may be susceptible to aluminum toxicity. The Global Healing Center contends that exposure to aluminum may cause "skeletal and neuromuscular problems."
