Secure your supply chain with our high-purity Tin-Cobalt alloy chemicals. Engineered for stable, nickel-free decorative coatings, delivering a consistent gun-metal finish for automotive and hardware applications.
Sn-Co Alloy (Tin-Cobalt) Plating Salt C is a specialized chemical formulation used in the electroplating industry to create a decorative, dark metallic finish often resembling chrome but with a warmer, "gun-metal" tone. Crucially, it serves as a compliant nickel-free plating alternative, addressing strict environmental regulations (like REACH/RoHS) that restrict nickel use in consumer goods.
For B2B procurement, this product is characterized by its stability in the plating bath (Salt C variant), high tolerance for impurities, and suitability for barrel and rack plating processes. It is the core raw material for surface finishing factories aiming to upgrade their environmentally friendly product lines.

When stored in a cool, dry place sealed in original packaging, the shelf life is typically 12-24 months. We ensure all shipped batches are freshly manufactured.
Yes, we understand the need for lab verification. Sample kits (1kg) are available for qualified B2B buyers to test compatibility with your base materials.
It is an excellent alternative for decorative applications requiring a similar aesthetic. While hard chrome has different hardness properties, Sn-Co offers superior color uniformity for decorative parts.
We support EXW, FOB, and CIF terms. Being a chemical product, we handle all necessary Dangerous Goods (if applicable) or General Cargo documentation for customs clearance.
"The stability of the Salt C batch is consistent. We switched to FengFan for our garment accessory line to meet EU nickel-free standards, and the color yield is perfect."
