We make our branding plates out of Aluminum or Brass. As a rule of thumb, aluminum is best for occasional use, and brass is the best choice for professional environments. Both yield identical results as far as sharpness and detail. Aluminum is, obviously, less expensive, and it’s considered safe for food contact. At high temperatures, aluminum is a bit softer than brass, and if heated incorrectly it can sustain damage. Brass is essentially impossible to destroy with high heat, and it withstands non-ideal conditions substantially better, like branding dirty, rough, or painted surfaces. When properly cared for, a brass branding plate will last for a lifetime.
