Surface Finishing

Chemicals, extreme temperatures, dust, moisture, and other contamination from the environment can impact the performance of your parts. We offer a broad range of coating types and methods, including anodizing, powder coating, and black oxide, to not only increase reliability in harsh environments but also extend the life circle of your custom parts.

Standard appearance of our surface finishes

Difference surface finishes can be applied to different materials. Find below listed surface finish varies from materials.

Treatment	Material	Thickness	Color
Anodizing	Aluminum	0.8-12 μm	RAL code, Pantone number
Nickel	All metals	5-30μm	Silver appearance
Passivation	SS steel and Carbon Steel	9～100 Å	Clear
Black oxide	Ferrous materials	0.8μm	Black
Bead blasting	All metals	#100, #120	Yellow or clear Iridescent
Powder Coating	All metals	10-80μm	RAL code, Pantone number
Zinc-Nickel	All metals	5-25 μm	Clear, Black , Iridescent
Chromate coating	Steel and Aluminum	0.25-1.0μm	Yellow or clear Iridescent

Anodizing

Anodizing treatment provides an aluminum oxide layer for metal parts, which protecting against corrosion & adding an optional color surface.

Specifications:

RoHS compliant

Type two ( color)

Class 1 (clear)

Class 2 (black)

Black oxide

Black oxide produce a magnetite layer on the surface for ferrous, non-ferrous, and powdered metals to Add Mild corrosion resistance and minimize light reflection

Specifications:

RoHS compliant

Hot black oxide

Mid-temperature black oxide

Cold black oxide

Chromate coating

Chromate coating is a type of conversion coating, which by producing a thin coating on the nonferrous surface, such as zinc, aluminum, tin plate to improved paint adherence.

Specifications:

Type two, RoHS compliant

Class1A: For max protection against corrosion, painted or unpainted

Class 3: For max protection against corrosion where low electrical resistance is required

Tempering

Tempering is a process of not only increasing metal hardness levels to obtain tougher and more durable properties but also dissolve solute-rich precipitates.

Specifications:

Quenched and tempered

Conditioning

HRC 10 to HRC 65

Part marking

Part marking is a process marking parts with product info, such as serial numbers, part numbers and logos, which allow the tracking of parts across the full product life circle.

Specifications:

Laser engraving

Silk printing

CNC Marking

0.05 to 3.0MM depth

Zinc-Nickel

Zinc-Nickel is Electrolurgy’s Plated offers a durable and highly corrosion-resistant coating and function. This surface finishing is frequently used due to its outstanding performance in high temperatures or aggressive environmental conditions.

Passivation

Passivation is finishing process by adding a protective oxide layer on metal surface to reduce chemical reactivity and increase corrosion resistance.

Bead blasting

Passivation is the finishing process by adding a protective oxide layer on the metal surface to reduce chemical reactivity and increase corrosion resistance.

Powder coating

Passivation is the finishing process by adding a protective oxide layer on the metal surface to reduce chemical reactivity and increase corrosion resistance.
