Alkaline Copper

JAR-TEX Industries specializes in alkaline copper plating. Alkaline Copper is used as an anti-galling solution when assembling similar metals. This coating is also used to mask parts prior to carburizing and increases the electronic conductibility of mating parts. Typical coating thickness of alkaline copper is in the range of 0.0002-0.0007 of an inch thick.

Zinc Phosphate

Zinc Phosphate produces a crystalline zinc phosphate coating that absorbs and holds lubricating oils. The coating, properly sealed and oiled, provides good corrosion protection during storage. Zinc Phosphate, when no oil is applied after coating, is also used as a primer for paint.

At Jartex, we can certify to MIL-ATL-16232 Specification.

Decorative Nickel Chrome

JAR-TEX Industries’ Decorative Nickel Chrome line is designed for industry. This allows us to handle a large volume of production items such as tooling, aerospace, medical, and any other industrial applications.Decorative Nickel Chrome has an appealing cosmetic appearance but is also extremely resistant to corrosion. All carbon steels, brass, bronze, and copper are suitable substrates for the application of nickel chrome.

At Jartex, we can certify to QQ-C-320.

Electroless Nickel

Electroless Nickel (E-Nickel) is a functional coating that is capable of offering enormous advantages to the engineering field. E-Nickel offers several advantages over conventional coating processes. Among the advantages are uniform deposit buildup on all surfaces without beading, the ability to coat irregular shapes uniformly, and the ability to heat treat the deposit to increase the hardness to 68 Rockwell C.

JAR-TEX Industries, Inc. offers a high-phosphorous nickel.

Corrosion Resistance:
Compared with an electrolytic-deposited nickel or chrome deposit of the same thickness, the corrosion resistance of Electroless Nickel is vastly superior in an extensive range of environments. The coating has very high inherent corrosion resistance and low porosity
Hardness:
46-48 Rc as applied but can be heat treated to bring the hardness up to 68 Rc
Abrasion and Wear:
The abrasion and wear resistance of the E-Nickel coating in the as-plated condition is superior to electro-deposited nickel and is equal to that of conventional hard chrome after heat treatment.
Thickness:
E-Nickel can be applied from .000050” to .003” thick with a uniform coverage.
Substrates:
E-Nickel can be applied to stainless steel, copper, beryllium, nickel, its’ alloys, and all steels.
Specifications:
MIL-C-26074B, AMS 2404, and AMS 2405

Note:
JAR-TEX Industries does not coat Titanium, Aluminum, or Magnesium.

Hard Chrome

Abrasion, friction, corrosion, heat and vibration are the most frequent causes of wear. Chromium coatings resist the effects of these elements by interposing a super hard, anti-friction, rust resistant layer between exposed surfaces, mating surfaces, and their surrounding parts.

Hardness:
Hard Chrome is 68-70 Rockwell C as applied.

Corrosion Resistance:
Hard Chrome is highly resistant against corrosive attack by water, salt solutions, and most chemicals. Its’ behavior in corrosive service is closely related to that of stainless steels.

Thickness:
JAR-TEX Industries Incorporated specializes in “flash” chrome coatings from .000050” to .001” thick.

Specifications:
QQ-C-320 and AMS 2406

Substrates:
Hard Chrome can be applied to all ferrous metals such as tool steels, cold roll/hot roll, high carbon, low carbon, etc. Non ferrous metals that hard chrome can be applied to include all stainless steels, beryllium, copper and copper alloys, bronze/brass, etc.
