Brass is one of the oldest metal alloys in the world, with its usage dating back to ancient times. Various civilizations had their own versions of brass, but the zinc-copper amalgamation in use today didn’t materialize until after the medieval period. Since then, brass has been used for making musical instruments, sculptures, and various bits in general construction. Its versatility and persistency over the years should give you an idea of why a brass channel is likely to serve you well in your project.
Curious about specifics? Well, brass is the ideal metal for applications that involve plenty of touching and moisture. Unlike other metals, brass has germicidal properties that prevent microbes from sticking to its surface for too long. This is why it is generally safe for you to drink from ancient brass goblets. Brass is also very durable and can withstand extreme pressures and temperatures, making it an essential material in shipbuilding.
Perhaps the biggest reason why you need to use brass is because it is one of the most sustainable materials in the world. Most, if not all, of the brass products you see today are made from recycled brass; some of them likely derived from decades-old brass scraps. Although it is still possible to manufacture brass from raw materials, the amount of work, energy, and resources expended simply make it too uneconomical.
