High Corrosion Resistant Alternative to Cadmium
AMS 2417 ASTM B841 ASTM F1941
Paramount Metal Finishing offers ZINC NICKEL plating to AMS 2417 and ASTM B841 on large parts up to 9 feet in length. Zinc nickel plating as the name suggests is a co-deposited coating of zinc and nickel.
Zinc Nickel is a high performance finish that offers maximum corrosion resistance especially for components used in severe environments. The zinc and nickel alloying creates a distinctive composition that will corrode at a much slower rate than zinc. The combination of approximately 10-15% nickel and the remainder zinc, can offer up to 10X the protection of traditional zinc plating.

Zinc plating, also known as galvanization or zinc coating, is a process of applying a protective layer of zinc to the surface of various metal objects under the ASTM B633. This plating technique offers several benefits, which include:
Corrosion resistance: Zinc is highly resistant to corrosion, making it an excellent protective coating for metal surfaces. The zinc layer acts as a barrier, preventing moisture and other corrosive elements from reaching the underlying metal. This helps to extend the lifespan of the coated object and reduces the risk of rust or corrosion. For example thickness classes: SC3 (severe) 12μm, SC4 (very severe) 25μm.
Enhanced durability: Zinc plating can significantly enhance the durability and longevity of metal objects. By providing a protective layer, it helps to minimize wear and tear, reducing the likelihood of surface damage or degradation. This is particularly beneficial for objects exposed to harsh environments, such as outdoor equipment or automotive components.
Cost-effective: Zinc plating is a relatively cost-effective surface treatment compared to other protective coating options. The process is efficient and can be applied to a wide range of objects, from small screws and fasteners to larger components. Additionally, the availability and low cost of zinc make it an economical choice for many industries.
Paint adhesion: Zinc plating provides an excellent base for paint adhesion. The surface of zinc is receptive to paint, allowing for better bonding and adhesion of the paint layer. This is especially relevant for objects that require additional protection.
Easy application: Zinc plating is a relatively straightforward process that can be applied using techniques, such as electroplating. It can be used on different types of metals, including steel, iron, and brass, providing versatility in application.
Overall, zinc plating offers a range of benefits, including corrosion resistance, enhanced durability, cost- effectiveness, improved aesthetics, paint adhesion, ease of application, and self-healing properties. These advantages make it a popular choice for numerous industries, including automotive, construction, electronics, and consumer goods.
Paramount Metal Finishing can accommodate zinc plating in both rack plating and barrel with some of the largest tanks on the east coast with working dimensions of 132”x48” in type II yellow and 100”x50” in type I clear (Trivalent/RoHS Compliant).

Corrosion will jeopardize the integrity of components of aircrafts, vehicles, and many other all types of equipment. Paramount Metal Finishing provides metal plating solutions that improve the corrosion resistance of metal parts for the aerospace, military, medical as well as industrial and energy industries. The following brief guide offers the best plating solutions Paramount Metal Finishing offers for corrosion resistance to help you decide which type of plating may best fit your requirements.
Because it does not need electric current, electroless nickel plating takes less time than electroplating processes like hard chrome. This type of metal plating improves corrosion resistance by creating a thick, even coating of nickel onto a metal surface. EN can plate down deep recesses of complex shapes. The protective nickel coating has a high hardness and is able to fill any flaws, making it the best metal plating solution for worn or degraded metal parts. Another advantage of electroless nickel plating is that after the plating process is complete, the metal part is ready to go—there’s no need for further surface finishing, grinding, or machining, unlike with other metal finishes.
Manganese phosphate is the hardest type of phosphate coating, and it provides superior corrosion resistance for steel parts. Unlike other phosphate coatings, manganese phosphate can protect steel parts even after they are broken in. Manganese phosphate coatings absorb lubricants on steel surfaces to enhance corrosion resistance and prevent the galling of parts like bearings, bushings, and fasteners that are subject to wear.
Zinc platings alone have marginal corrosion resistance, but provide even better protection when alloyed with nickel. Zinc nickel plating protects steel, copper, and brass against high temperatures. It can also minimize galvanic corrosion caused by dissimilar metals. This type of metal plating is commonly used in the aerospace industry for landing gears, flap tracks, and other metal parts. It’s also used widely in the defense, automotive, heavy equipment, and agricultural machinery industries. Zinc nickel is a sacrificial coating and is an environmentally safe alternative to cadmium that offers equivalent and, in some cases, better corrosion resistance.

The annual global cost of corrosion is $2.5 trillion, equivalent to 3.4% of the worldwide GDP. In the US, the annual cost of corrosion surged past $1 trillion, affecting our national GDP by 6.2%. Corrosion affects infrastructure, transportation, production & manufacturing, utilities, and the federal government.
Chemical based methods to control the detriments of corrosion include:
Per the values given, the traditional methods to control corrosion fall short, In fact, far short.
In a major development to minimize corrosion, thereby improving field service life of parts in challenging conditions, Zinc – Nickel alloy (ZN-Ni) plated finishes provide significant benefits. These include not only corrosion protection, but improved hardness, service life, and wear resistance.
Straight zinc plated deposits provide sacrificial corrosion protection over steel substrates. It is accomplished by the zinc deposit’s anodic potential to corrode first, protecting the steel base. This has been an industry accepted application for decades.
Paramount Metal Finishing offers a unique, significant improvement to corrosion protection. It is the Zinc – Nickel alloy deposit (Zn-Ni), composed of 85% Zinc & 15% Nickel. The focus of corrosion protection is immediately obvious by results of the ASTM B-117 Salt Spray Testing, on equivalent deposit thicknesses.
Salt Spray Results for Electroplated Deposits
|Deposit||Hours to White Corrosion||Hours to red Corrosion|
|Zinc – Nickel (Zn-Ni)||350-400||1,000-1,200|
The corrosion protection afforded by a deposit of Zn-Ni significantly outperforms straight Zinc by 2.7:1 (white corrosion) and significantly by 4.9:1 to red corrosion.
The Zn-Ni alloy deposit consists of 85% Zinc and 15% Nickel. Deposits normally range in thickness of 8-14 um, followed by a trivalent chromate of 0.06-0.1 um thickness.
Zn-Ni deposits approach 450 Vickers hardness. By comparison, Zinc deposits fall below 150 Vickers.
Zn-Ni deposits resist thermal stresses approaching 200 degC (392 degF) compared to Zinc deposits at only 120 degC (248 degF.
Other outstanding features of the Zn-Ni deposit include:
Paramount Metal Finishing applies Zn-Ni to a variety of commercial and military parts, including: automotive, power generation, fasteners, construction, agricultural equipment, firearms, aerospace, lawn & garden, transportation, and heavy equipment.
Finishing capabilities range from standard parts to larger sizes and dimensions,
