Manufacturers can now finish iron and steel components with MicroLok AO, a low temperature, environmentally friendly process that serves as a low-cost replacement for polluting cold blackening.

• Forms a non-toxic, aluminum oxide conversion coating that is 1.5 microns thick
• Silver/black in color
• Tightly adherent to the metal surface
• When sealed with a rust preventive, the finish provides robust corrosion protection that is better than cold blackening at half the cost, without undesirable pollution hazards
• Avoids the use of EPA regulated (copper & selenium) chemicals
• Contains no regulated chemicals
• Anti-galling protection to aid in assembly and start-up
• Temperature stability up to 1,400 F
• Safe 120-140 F operation with no boiling or splattering
