Pretreating alloys is the best way to achieve a perfect surface for painting and coating. We offer a range of magnesium and aluminum pretreatments. Our high-quality processes make the whole process extremely cost-effective. All our coatings meet the MIL-DTL-81706B standard and include multiple RoHS-compliant options. Alodine 5200 RoHS-Compliant Coating Chromium-Free Product Specifically for Treating Non-Ferrous Alloys Excellent Base for the Bonding of Adhesives & Organic Finishes No Toxic Fluorides Electrically Conductive (It Is Chrome-Free) Alodine T-5900 RoHS-Compliant Coating Trivalent Cr III System Used When You Need Electrical Conductivity Excellent Conductivity with Aluminum Reacts Slightly Better Than the Base Metal Magnesium for Conductivity

Passivation

We provide passivation services to all 300-series austenitic stainless steels and many more. Alloy processes are performed to meet the requirements of the QQ-P-35 and A-967-05 standards. Certification is available upon request. Please contact us for assistance with your specific requirements.

Process Definition

Passivation is a chemical process that removes sulfides and ferrous materials from the surface of stainless steel. However, if the product is touched by a ferrous material after processing, it nullifies the passivation process.

Benefits of Passivation

• Maximizes Corrosion Resistance
• Removes Surface Contamination from Machined & Peened Parts
• Removes Exposed Sulfides from the Surface of Stainless Alloys (Which Can Act as Corrosion Initiation Sites on the Surface of the Fabricated Product)
