Brass 385 Square Tube
Brass 385 is commonly used for ornamental and decorative projects. It is common to see trim, thresholds, hinges, and hardware in 385.
Because of this, it is also known as “Architectural Bronze.” But this is incorrect. While both have copper as their main alloy, bronze is mostly alloyed with tin. Brass on the other hand, is mostly alloyed with zinc. Brass 385 is definitely brass, not bronze.
A bit of trivia for the day: Brass was one of the first metals used by humans. Archaeologists have found brass tools in China that are about 7,000 years old!
Brass 385 Square Tube vs Brass 272
What is the difference between 385 and 272, the other common alloy for brass tubing? 272 is stronger than 385. But 385 is more corrosion resistant, easier to machine, and polishes up better.
If strength is the most important aspect of your project, use 272. However, if decoration and longevity are the key concerns, use 385.
Brass 385 is mechanically similar to 360 “Free Machining Brass.”
385’s yellow-gold color is a very good color match with both 280 Muntz Brass and 464 Naval Brass. It has good corrosion resistance when outdoors, though only fair resistance to weathering in marine environments. Like all brasses, 385 is nonmagnetic, and is pretty heavy. Also, 385 is extremely easy to machine, and has great formability when heated. But it is rated as poor for cold working.
It can be soldered and brazed, but cannot be hardened by heat treating.
