Anodize |
Anodize finishes are intended to provide corrosion protection and abrasion resistance for aluminum and aluminum alloys
(Clear, Black).
ASTM B 580 |
| Chem. Film (Iridite) |
Chem. Film or Iridite is primarily used for mild corrosion protection with low electrical resistance and also improves paint adhesion on aluminum and aluminum alloys.
ASTM B 449 |
Black Polyurethane
E-Coat |
Black Polyurethane E-Coat is applied with an electrical current in an immersion process that results in a very uniform coating, even on complex parts. The thickness (0.2 to 1.0 mil) is lower than liquid paints or powder coat, making it an ideal finish for parts with close tolerances and threaded parts. Corrosion resistance is good, chip resistance is excellent, and the black finish is quite decorative. |
| Electroless Nickel |
Electroless nickel is a hard coating that provides corrosion protection, wear resistance, electrical conductivity, and consistent thickness.
ASTM B 733 |
| Electroless Nickel/Tin |
Electroless nickel/Tin is a bright tin-plating over a nickel coating that provides corrosion protection, electrical conductivity. Excellent for electronics where solder-ability and RF control are needed. |
| Electrolytic Nickel/Tin |
Electrolytic Nickel/Tin provides corrosion protection and electrical conductivity. Excellent for electronic fasteners and contacts where solder-ability is required. |
Magni 550
(Dip spin) |
Magni 550 combines an electroplated zinc and chromate underlayer with an aluminum-rich epoxy topcoat. The zinc layer provides sacrificial protection of the substrate and the topcoat creates a highly corrosion resistant barrier. Salt spray protection over 1000 hours is normal, with up to 3000 hours measured on some parts. A friction modifier provides low torque for fastener applications. The color is flat silver/gray. The cost is about twice that of zinc. |
| Special Etch |
Special etch is a chemical etching process that cleans and brightens most aluminum parts. |

Electrolytic Nickel |
Electrolytic nickel is a hard coating that provides corrosion protection; wear resistance, electrical conductivity, and bright finish. ASTM B 689 |
Electrolytic Nickel/Tin |
Electrolytic Nickel/Tin provides corrosion protection and electrical conductivity. Excellent for electronic fasteners and contacts where solder-ability is required. |
Electrodeposited Tin |
Electrodeposited Tin provides corrosion protection and electrical conductivity. Excellent for electronic fasteners and contacts where solder-ability is required. ASTM B 545 |

| STAINLESS STEEL |
| Passivate |
Passivate is a process that removes iron and foreign metals from the surface of stainless steel to help prevent oxidation and rust from forming on the surface. |

| STEEL & STEEL ALLOYS |
| Clean and Oil |
Clean and oil is used to clean mill scale and dirt from steel parts and is followed by a dry to touch oil to protect from corrosion. |

| Zinc Plate |
Zinc plating is a widely used coating that provides sacrificial corrosion protection for steel parts. This coating is applied using either barrel or rack methods (Clear, yellow, black, or olive drab). ASTM B 633 |
| Zinc Cobalt Plus |
Zinc cobalt plus is zinc plating that incorporates small amounts of cobalt metals into the plating. A clear hex free chromate is applied which is then sealed. This provides excellent corrosion protection. This is a barrel plating process and is available in “clear” or “bright” only. Meets European ELV standards. ASTM B 840
