Electrically, the conductivity of Black Zinc Nickel plating ensures shell-to-shell continuity of less than 2.5m and less than 5m after 500hrs salt spray chamber time. This superior electrical performance ensures high levels of EMC screening can be maintained within sensitive systems in demanding situations.
Aesthetically, black nickel plating provides a reflective and shiny black look when plated on bright nickel. When plating over dull substrates or matte finishes you will not receive the reflective or shiny attributes. The advantages of using black nickel over other options such as black chrome is that on black nickel does not show smears such as finger prints for example, and has a more uniform color.
Brass, which is an alloy made of copper and zinc, can be varied to create a wide range of brasses with varying properties, is widely used for decorative applications in antiques and ox finishes. Brass plating is also a great alternation for sealing zinc die-castings for post molding operations.
Brass plating provides an excellent diffusion barrier preventing components of the base material from migrating into the subsequent plating layers.
We run small to high volume production runs and can plate brass on a variety of substances including nickel, steel, bronze, stainless steel, and zinc die casting. We offer the highest quality brass plating services at the best price.
Cadmium plating is under scrutiny because of the environmental toxicity of the cadmium metal. However, cadmium plating can be and is still widely used in some applications such as aerospace fasteners and it remains in military and aviation specs. Consequently, we are committed to investigate alternative coatings that can match the performance of cadmium without the accompanying environmental problems.
Cadmium plating (or “cad plating”) offers a long list of technical advantages such as; excellent corrosion resistance even at relatively low thickness and in salt atmospheres, softness and malleability, freedom from sticky and/or bulky corrosion products, galvanic compatibility with aluminum, freedom from stick-slip thus allowing reliable torqueing of plated threads, can be dyed to many colors and clear, has good lubricity and solderability, and works well either as a final finish or as a paint base.
If environmental concerns matter, in most aspects cadmium plating can be directly replaced with gold plating as it shares most of the material properties, but gold is more expensive and cannot serve as a paint base.
We offer CAD plating responsibly and apply within the guidelines of the Environmental Protection Agency. We provide CAD plate to United States Military specifications and post-treated chromates are available.
Copper plating creates an outstanding barrier layer that can cover substrate metals and alloys. Copper plating provides an easy-to-plate, level, and in some cases, smooth substrate, making it even more popular than nickel plating for certain metal finishing applications. Although it can be used independently, copper is typically used as an under plate for deposits such as nickel, tin, tin/lead, gold or silver.
Copper plating provides an excellent diffusion barrier which prevents components of the base material from migrating into the subsequent plating layers. Copper plating generates high electrical conductivity, which has made it an excellent and inexpensive choice for high tech products as well as other applications.
Yielding excellent wear and corrosion resistance, electroless nickel is an autocatalytic plating process resulting in a reflective layer of nickel-phosphorous. The total build up plating process provides uniformity on all surfaces, making post machining unnecessary when dimensions are accurate. DiFruscia Industries offers surface treatments to increase hardness, lubricity and corrosion resistance.
All of DFI-Electroplating’s electroless nickel process provide freedom from porosity and have a controlled hardness heat treatable to 68 and 70 Rockwell C, respectively.
Other benefits include its natural lubricity, which provides excellent release properties, an infinite throw, which eliminates auxiliary anodes, a solderable hard coat for light metals and a self-polishing effect when used in molding operations.
Electrolytic nickel plating provides a non-uniform thickness of deposit of the surface of its component, with the thickness being dependent on the current density of the part surface. Electrolytic nickel plating is also one of the most versatile metal finishing process with end uses ranging from decorative finishes to functional applications. Engineering applications of electrolytic nickel coatings are to improve or modify surface properties including corrosion resistance, magnetism and resistance to oxidation at high temperatures.
Nickel sulfate is often referred to as “bright nickel” and is used in applications where decorative reflectivity is required. Sulfate nickel does not perform well in applications where ductility or solderability is an important consideration.
Gold, being a precious metal meaning it will not oxidize in air, allows for its electrical conductivity to stay uniform over long periods of time. Benefits of gold plating include corrosion resistances, good solderability, and when alloyed with cobalt, good wear resistance.
In regards to application use, components that require gold plating are those used in electrical switch contacts, connector pins and barrels, and other applications used in intermittent electrical contact. Gold plating has widespread use for medical and dental applications as exemplified in the production of certain mechanical systems used in microsurgical procedures. Gold’s anti-corrosive and heat-shielding properties are ideally suited for the aerospace industry in the manufacturing of rocket engines.
While Nickel Sulfamate can be used by itself, it is typically used as an under plate for deposits such as, tin, tin/lead, gold, palladium or silver. Nickel provides a diffusion barrier that prevents components of the base material from migrating into the subsequent layers of plating.
Precious metals are valued for their scarcity, its high economic value, and lustrous appearance. Common application of precious metals are its use in the minting of bullion coins, the manufacturing of the fine jewelry, with the most common elements being gold, silver, and platinum. The benefits using precious metal plating on components include increased aesthetic appeal, superior resistance against corrosion and wear, and are highly ductile and conductive. Though it’s more costly its costs are offset by the consistent superior quality over time.
DiFruscia Indsutries offer a wide variety of plating services for unique plating requirements. We will adapt our plating equipment to meet the specific needs of our customer allowing us to offer services that can deposit metals with high precision to reduce the amount of precious metal being used in the plating process and the cost to our customers.
Silver has the most applications in comparison to any other plated metal. Silver plated metal objects are used in almost any industry and it’s difficult to replace any other metal in its place. In addition to this, Silver is the least expensive precious metal of its group. Silver also has the highest electrical and thermal conductivity and light reflectance of any current known metal, and the lowest weight and melting point of the precious metal group.
Common application of silver plating are to increase a product’s life cycle by replacing the material coating of choice of a tin or alloy coating. Silver plating is also commonly used to plate components used in electrical contacts such as conductors, silver plating is used in specialized mirrors, windows coatings and in catalysis of chemical reactions.
Tin plating is used in applications to protect ferrous and nonferrous surfaces. Components that require tin plating are those commonly used in electronics, automotive, appliances, computer hardware, medical and food processing. Because tin has great ductility it allows a coated base metal sheet to form many different shapes without damaging the surface tin plating layer. Tin plating also provides sacrificial protection for copper, nickel, and other non-ferrous metals, with the exception of steel.
DiFruscia Industries offers lead free tin plating to preserve the solderability of underplated deposits and to offer corrosion protection and superior electrical conductivity where it’s needed.
Zinc electroplating is the method of depositing zinc metal on the surface of another metal, such as steel, by immersing the fasteners in an appropriate plating bath and applying an electrical current. The thickness of zinc plating is dependent on the time the component is spent in the plating bath, the amount of current used, and the chemical composition of the bath.
The benefits of zinc plating are corrosion resistance to the steel components by acting as a barrier and a sacrificial coating. Due to zinc being more electrochemically reactive than steel the zinc plating corrodes sacrificially when exposed to a corrosive environment. This delays the rust formation on steel components even after portions of bare steel are exposed.
Zinc iron plating offers enhanced corrosion protection over normal zinc plating because when alloyed with small quantities of iron, this protection further improves the use of thick passivation and topcoats. Zinc iron along with zinc plating are two of the most commonly used metals for plating.
Zinc nickel plating provides superior sacrificial corrosion resistance and can be readily passivated. Zinc nickel plating is the preferred plating choice for automotive applications due to its extremely high corrosion resistance. Zinc nickel plated components can resist more than 10,000 hours of neutral salt spray with no effect on the dimensional tolerance of the threaded components.
