Universal Black Oxide (UBO) is North Carolina’s premier metal finishing facility specializing in Black Oxide and Passivation and located less than 30 minutes from the vibrant city of Charlotte, NC, home to NASCAR. 


Our advanced blackening process increases corrosion protection, enhances resistance to abrasion and improves the lubricity of iron components. Our best-in-class sealer offers 180 hours salt spray analysis. Parts that have blackened using the Universal Black Oxide Process are uniformly deep black and will stay deep black. Our Universal Black Oxide Finish is unrivalled: it is where art and science meet. 

Universal Black Oxide processing is ideal for aviation components, automotive components, machinery, fasteners, springs, firearms, specialty tooling, gears, hand tools and many other components where a durable black, clean finish is desirable.
