Conversion coating type: Alodine coating Application area: Primer for military‑grade coatings Partners: AVIC, Shandong AVIC, Hui, and other enterprises Advantages of the conversion coating: Both the natural‑color and yellow‑tinted coatings have been incorporated into MIL‑C‑5541E, the U.S. military standard for “Chemical Oxidation of Aluminum and Aluminum Alloys,” and are now widely adopted in domestic military specifications. Due to hexavalent chromium contamination, few manufacturers outside the southern military‑industrial complex currently employ this process, making it a relatively rare and specialized technology.
Conversion coating type: Anti‑fatigue oxide film Application areas: Aluminum alloy components in missile propulsion systems, control surfaces, aerospace vehicles, and weapon systems Partners: Fenghua Science & Technology and other enterprises have become strategic partners Advantages of the conversion coating: Traditionally, this type of oxide film was produced via chromic acid anodizing; however, due to environmental concerns, boron–sulfuric acid anodizing has now largely replaced it. The challenge is that, under identical processing conditions, different aluminum alloys yield significantly varying film characteristics. Through years of production experience, our company has developed a proprietary technology that has been widely recognized by local defense‑industry customers. Nevertheless, insufficient marketing efforts have occasionally led to communication gaps between our clients and our enterprise.
