With a proven track record of exceeding 1000 to 1200 hours in a salt spray test, Alkaline Zinc plating stands out for its reliability and performance.

Zn-Fe (Zinc-Iron)

Uncover the benefits of Zn-Fe, also known as zinc-iron plating, a process that deposits a layer of zinc-iron alloy onto metal substrates to enhance corrosion resistance and impart additional desirable properties. Renowned for its solid weldability and good ductility, Zn-Fe ensures components maintain excellent surface appearance. Its even distribution, suitable for both even-edged and irregular components, sets it apart, along with superior lubricity and a high level of hardness. With a remarkable salt spray resistance exceeding 480 hours, Zn-Fe is an excellent choice for intricate and complicated shapes, offering reliable protection and lasting performance.

Tin (Sn)

Step into the realm of tin plating, a process that involves depositing a protective layer of tin onto metal substrates, offering valuable properties such as corrosion resistance, excellent solderability, and more. Tin, known for its soft, malleable, and silvery-white characteristics, is not only abundant but also a cost-effective solution. Beyond its affordability, tin plating provides a whitish-gray color ideal for achieving a dull or matte appearance. However, when a touch of luster is desired, it can effortlessly transform into a shiny, metallic finish. In addition to its aesthetic versatility, tin plating ensures reliable protection against corrosion and exhibits good conductivity, making it a multifaceted choice for various applications.

Chromate Conversion Coating (CCC)

Immerse aluminum and its alloys in a controlled chromic acid bath, and witness a chemical conversion reaction unfold at the metal's surface. The result? A sophisticated, non-crystalline, and impermeable coating, featuring a thin aluminum oxide film enriched with chromates and dichromates. This coating acts as a versatile shield, offering corrosion protection and boosting resistance for both bare and painted surfaces. Not stopping there, it enhances the adhesion of paint or primer coatings, providing not just protection but also an attractive decorative finish. Tailored for electronic components, CCC delivers a comprehensive solution, harmonizing corrosion protection with aesthetic appeal.

Electroless Nickel Coating

Experience the deposition of a nickel-alloy coating through chemical reduction, a process distinct from traditional electroplating as it doesn't require an electric current. Our Electroless Nickel Coating offers excellent corrosion protection, forming a uniformly thick layer across the entire substrate, including slots, holes, and inside walls of tubing. This process ensures not only robust corrosion resistance but also imparts good hardness, wear resistance, and bending properties to the coated surfaces.

Surface Conditioning

Experience a meticulous process of controlled micro-attack and impurities removal, ensuring a thorough cleaning of the substrate. Our method removes dirt, grease, oxides, and other contaminants, creating an ideal surface for enhanced adhesion in subsequent processes. This meticulous technique results in an excellent finish, particularly beneficial for electronic components.


Dive into the world of anodizing, an electrochemical oxidation process that transforms metals and alloys, particularly aluminum, into a robust and wear-resistant masterpiece. Through the controlled application of current, an oxide film forms on the aluminum surface, ushering in a range of benefits. Experience enhanced hardness as the process generates a thick and resilient coating, significantly boosting wear resistance. Anodizing excels in delivering precise thickness control, ensuring uniformity and consistency throughout. This method isn't just about toughness; it also enhances dielectric strength, making it ideal for applications demanding electrical insulation. Plus, with its tight tolerance capabilities, anodizing caters to specific engineering requirements, making it a versatile and reliable choice.

Hard Anodized

Embark on a journey of durability with Hard Anodized finishes. This electrochemical process immerses aluminum in an acidic electrolyte, subjecting it to an electrical current that transforms its surface. The "hard" in Hard Anodized signifies a thicker, more robust oxide layer achieved through an extended and controlled anodizing process. The result? A surface that's not only significantly harder than untreated aluminum but also scratch-resistant and highly durable. Tailored for environments demanding high abrasion or corrosion resistance, Hard Anodized shines where functionality takes precedence over cosmetics. With coatings typically 0.002” thick and available as class 1 (non-dyed), it provides exceptional abrasion resistance that won't peel or come off, all in an environmentally friendly package.

Soft Anodized

Delve into the versatility of Soft Anodized finishes, where aluminum undergoes an electrochemical treatment with an acidic electrolyte. The resulting oxide layer, while softer and less thick compared to its hard counterpart, opens doors to various applications. Soft anodized aluminum is a preferred choice for decorative or aesthetic purposes, enhancing corrosion resistance and creating a smoother surface texture. Beyond aesthetics, this process boosts corrosion resistance and durability, facilitating improved adherence for paint or organic coatings. With meticulous control over dimensional tolerances within a few microns, Soft Anodized delivers abrasion resistance that doesn't peel or come off, all while being environmentally friendly.

Acid ZnNi

Embark on the realm of Acid Zinc plating, a meticulous electroplating process utilizing acid solutions. Renowned for its high electrodeposition rate and conductivity, Acid ZnNi is a robust choice despite its non-bio-friendly nature. With minimal waste, it boasts excellent corrosion resistance, particularly at elevated temperatures, making it an ideal coating for nodular iron. Notably, it stands out with the highest abrasion resistance among all zinc alloys, effectively preventing galvanic corrosion when plated. The process showcases high leveling capability and imparts a dazzling brightness to the final finish.


Dive into the SnZn (Tin-Zinc) plating process, a harmonious blend of cost-effectiveness, environmental consciousness, and versatile performance in corrosion protection and solderability. This reliable choice exhibits high corrosion resistance, coupled with exceptional throwing power, ensuring uniform thickness even in deep recesses.
