"The Lumiclad process from Birchwood Casey forms a non-dimensional black oxide finish on all aluminum&amp;nbsp;surfaces, and is designed to be clean, durable and tightly adherent to metal substrate.&amp;nbsp;The finish has an&amp;nbsp;inherent lubricity that aids in break-in and resists galling, making it an ideal finishing choice for&amp;nbsp;product assemblies with sliding contacts."^^<http://www.w3.org/2001/XMLSchema#string>
