Metal Finishing

Whether your finishing requirements are relatively simple or highly sophisticated, Techtrix is an established and reliable supplier.  We offer a variety of services in our modern facility which include electroplating and metal finishing using modern, fully programmable plating machines.

We compliment our finishes by providing secondary operations like Hydrogen Embrittlement Relief, Heat Treatment, EMC - EMI shielding, and even assembly.  Our goal is to provide you with the necessary services to take you from what you have to what you want - on time and within cost restraints.

Alodine - a chromate conversion coating that is applied only to the surface of aluminum.  It gives good corrosion protection as well as providing a excellent base for painting.  The color can vary from colorless to golden - iridescent - brown.

Cadmium - A silver-white deposit used to minimize galvanic corrosion on parts of assemblies consisting of dissimilar metals such as brass and steel, for its corrosion protection properties in certain harsh environments, and for its high lubricity.

Copper - A reddish deposit used for plating through holes on circuit boards in the electronics industry, on steel wire used in making high-strength electric cable, and as a stoppoff to prevent case hardening on selected areas of iron and steel surfaces.  All pennies made since 1981 are copper-plated zinc.  Copper is also the first layer in "triple chrome" plating.

Gold - A yellow deposit heavily relied upon in the electronics industry to provide long-term, dependable electrical contact, solderability, temperature resistance and corrosion protection in all kinds of devices including telephones, pagers, cellular phones, printed circuit boards, televisions, satellites, rockets, and so on.  Gold is also a common deposit on jewelry, pens and optical products.

Nickel - A silver-white deposit used generally on industrial products for corrosion protection, and in the chemical and food processing industries to prevent iron contamination.

Passivation -  The use of an acid solution to render the surface of stainless steel in a "passive" state that enhances its corrosion resistance.

Silver - Used on tableware and hollowware because of its resistance to foods, as well as in jewelry.  Functional uses include preventing galling or seizing of metal surfaces under high loads, such as on bearings, threads on stainless steel bolts and on titanium compressor blades.  It is also used in the electrical and electronics industries because of its outstanding conductivity.

Tin - A white, non-toxic, solderable, soft deposit useful for its resistance to corrosion and tarnish.  Since tin is a non-toxic, it is used as a coating on sheet steel for making "tin cans" as well as on food handling equipment.

Zinc - A bluish-white deposit which serves as an inexpensive decorative and sacrificial protective coating against atmospheric corrosion of iron and steel parts.  It is commonly used on nuts, bolts, wire goods, fasteners, stampings and sheet metal parts.
