There are several good metal choices for exterior outdoor light fixtures, some of which are more durable than others. Let’s start with the most high end material, which, in this case, bronze will be the first article on this topic – then we’ll work our way down the list:
Bronze: There is a perceived luxuriance characteristic with the word “bronze”. Bronze metal has been used, historically, for weapons, castings for tools and hardware, sculpture and an array of beautiful commodities. Bronze exterior outdoor lighting fixtures assembled from castings, are usually fabricated from an alloy mixture of copper, zinc and silicon. The alloy mixture has a low melting point, reaching fluidity at about 2000 degrees Fahrenheit, which creates the perfect molten liquid for adhering to the casting process.
Once the castings have cooled, the bronze material is considered corrosive resistant. Bronze becomes the perfect metal material for outdoor lighting fixture use – being superb in all types of weather environments. Bronze castings can be seamlessly connected when welded or soldered, to make an outdoor fixture or outdoor lantern look like one continuous piece. By protecting the outdoor lantern with wax or lacquer, you can achieve a natural aging or patina over time that will lend itself beautifully to your custom designed outdoor lighting fixture or lantern.
