Why Magnesium is a Game-Changer for Lightweight Applications As technology evolves, industries like defense and medical manufacturing demand lighter, stronger materials. Magnesium fits the bill, offering exceptional strength-to-weight advantages. But plating magnesium? That’s where precision and expertise matter most. The Challenge of Plating Magnesium—And How AST Solves It Magnesium’s reactive nature makes it incompatible with standard plating chemistries. At AST, our process includes proprietary chemical buffering from start to finish, protecting the base metal and ensuring flawless adhesion. Decades of Experience, One Purpose-Built Line Since 2001, AST has specialized in magnesium plating. Our first attempts were rocky, but over 20 years later, we’ve refined the process into a dependable, repeatable operation with a dedicated line built just for magnesium. Real-World Results for High-Performance Industries We’ve plated tens of thousands of magnesium components—from communications chassis for military field use to ultra-light enclosures for portable oxygen generators. After nickel plating, some parts Read more

Scaling Up: How AST’s Tank Sizes Enable Industrial-Scale Production When it comes to production plating, tank capacity is more than a convenience, it’s a competitive advantage. With tanks ranging from 50 to 1,000 gallons, AST can handle large parts, prototype plating, or bulk processing with outstanding efficiency. Magnesium Line Tank Dimensions: Built for Production Our magnesium line includes 200-gallon tanks with working dimensions of approximately 42” x 36” x 30”. These are perfect for high-volume, long-run orders like a recently completed military communications project. Have Other Alloys that Need Bigger? For other alloys like steel, stainless steel, and copper parts Advanced Surface Technology can deploy tanks up to 1,000 gallons to perform electroless and electrolytic nickel, and citric passivation while maintaining plating consistency. Why Bigger is Better for Consistency and Cost Precision Chemistry Monitoring on Every Load Even with large volumes, our plating quality is uncompromising. Our lab tests chemistry Read more

A Coating That Goes Beyond Protection The defense and aerospace industries require components made with high precision to tight tolerances. Every component must perform flawlessly, often under extreme conditions. That’s why electroless nickel plating is frequently the coating of choice for mission-critical parts. Often referred to as an “engineering coating,” electroless nickel offers both corrosion protection and precision to plus or minus 0.0001” of thickness. ___________________________________________________________________ Why Defense Engineers Choose Electroless Nickel 1. Uniform Thickness on Complex GeometriesUnlike electrolytic plating, which relies on electrical current, electroless nickel is deposited through a chemical process. This means quality plating can be applied to internal cavities, deep bores, and intricate geometries. Clearly, this meets the needs of critical components in weapons systems and flight hardware. 2. Hardness and Wear ResistanceFormulations that vary the amount of phosphorus in the electroless nickel deposit can increase hardness and improve corrosion resistance. Higher deposit hardness can improve Read more

When selecting a metal coating for your application, cost is always an important factor. While it might be tempting to choose the least expensive option, it’s critical to understand the trade-offs in durability, performance, and long-term value. Here, we explore how the cost of different coating types compares, particularly focusing on our PEN-TUF® process—electroless nickel with PTFE. Relative Coating Costs There are many effective solutions for environments that require corrosion protection and where the parts are not subject to abrasion. They are relatively low in cost but are often quite effective. Examples include: As performance requirements increase, so does the need for a higher quality coating. For maximum corrosion protection and superior electrical conductivity, precious metal plating is often the best option: Of course, precious metal plating can be costly, especially since gold is currently trading at over $3,000 per troy ounce.
