How to find the right Bronze Angles AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Bronze Angles

Actual alloy
Confirm the UNS number. Most extruded 'bronze' angle is architectural bronze C38500, which is a leaded brass. True bronze angle such as silicon bronze C65500 is uncommon. Architectural bronze suits trim and looks, but it is a brass and does not have the corrosion resistance of tin or silicon bronze in seawater or other wet structural use.
Leg and thickness dimensions
Match both leg lengths and wall thickness to the drawing. Check whether legs are equal or unequal. Angle is usually cut to fit existing trim or framing, so a mismatched leg cannot be fixed easily.
Corner profile
Choose sharp inside and outside corners or radiused corners to suit the mating part. Extruded angle often has an inside fillet that will not sit flush against a square edge.
Surface finish
Mill finish needs polishing or a lacquer or patina. Pre-finished stock needs protection during handling. Angle is usually visible trim, and copper alloys tarnish quickly when untreated.

What to avoid

  • Listings that say 'bronze' with no alloy number. These are usually brass.
  • Using architectural bronze (C38500) for submerged marine use, where it can dezincify.
  • Assuming a 'bronze color' coated aluminum or steel angle is solid bronze.

Questions

Is architectural bronze really bronze?

No. C38500 is a leaded brass named for its bronze-like color. It works well for trim but is not a tin or silicon bronze.
