Product Details, Specifications, and Technical Information

See Brass Tolerances

Brass Square Tube alloys 385 or 280 are also known as Architectural Bronze even though they are actually a brass. 385 and 280 brass are color matches, and will be stocked in one alloy or the other depending on the size/part number. They polish to an excellent finish, resist corrosion in non-marine environments, and machine comparably well to 360 free-machining brass. They are easy to braze and solder but should not be welded. 385 and 280 are typically used in decorative architecture applications and ornamental hardware.
