Hard Coating Ceramics
Series 100
For Aluminum Magnesium, and their Alloys

Coating Specifications

Suitable Alloys

Series 100 coatings can only be applied to aluminum. To optimize coating performance, low copper alloys (less than 5%) and low silicon (less than 7%) are preferred. The following alloys have been coated successfully:

Wrought Alloys... 3003, 5052, 6061, 6063, 6262 and 7075 (processing of 2000 series upon request). Sandcast Alloys... 319, 355 and 356 Die Cast Alloys... 360 and 380 (reduced hardness properties)

Coating Thickness

Coatings consist of an actual surface penetration and surface growth. The normal coating thickness on wrought and sandcast alloys is 0.002 inch, which consists of an increase in the surface dimension of approximately one-half this thickness or 0.001 inch. Standard process tolerance is ±0.0004 inch for most alloys.

Precise process control and coating uniformity permits coating of close tolerance dimensions, threads, and holes. Blind holes coat the same as exterior surfaces if the depth does not exceed approximately 1.5 times the hole diameter, and through holes will coat uniformly if the depth does not exceed approximately 3 times the diameter.

Surface Finish (RMS)

The application and specific performance factors will generally dictate the required RMS surface value before coating.

Our Series 100 coatings will increase the RMS surface roughness on wrought alloys between 5 to 15 micro-inches and between 20 to 60 micro-inches on cast alloys, and is not predictable. Although the increase in roughness is significantly offset with our polymer infusion, we recommend that you finish to an RMS value better than required.

Hardness

Surface hardness approaches that of case-hardened steel. Typical hardness ranges from 45 to 65 RC, depending on the specific Series 100 coating being applied and the aluminum alloy. It is important to point out that hardness values are typically determined by a point loading indentation test, although this is not an acceptable method based on the soft aluminum under the coating.

Wear and Abrasion Resistance

Applied to a surface of 12 micro-inches or smoother, the coating exhibits superior abrasion resistance, comparable to hardened tool steel or chromium-plated steel having the same surface finish.

Low Friction

Series 100 coated surfaces are smooth and provide permanent dry film lubrication and a lower coefficient of friction. Values are similar to Teflon® and typically range between 0.08 and 0.12. The amount of friction reduction depends on size of load, sliding speed, temperature, and the material and micro finish of the contacting surface. To optimize low friction, the surface should have a nominal 8 RMS or better finish before coating.

Chemical & Corrosion Resistance

Since 1971, we've also specialized in the application of Solid Film Lubricants. Our SFL solve the problems of anti-galling, corrosion, low friction, lubrication, high temperature and wear; we offer exceptional performance properties between mated surfaces, not previously attainable.

Non-Stick (Release) Properties

Based on the unique combined ceramic/polymer properties of Series 100 coatings, few materials will permanently adhere to the coated surface.

Endura® coatings are used extensively throughout many diversified industries, such as baking, packaging, plastic and urethane molding, medical, and pharmaceutical, just to mention a few, and are also USDA Approved and FDA Compliant.

Operating Temperature Range

Many coatings will withstand severe temperature extremes without loss of physical properties, and are designed for operation from cryogenic to 450°F continuous operation, to 500°F intermittently. Coatings are available to 1000°F.

Thermal Properties

Coatings display high thermal conductivity for rapid heat and cold transfer. Coated surfaces provide heat distribution superior to uncoated aluminum, and a predictable uniform heat path.

Electrical Properties

Coatings possess high dielectric strength over a wide frequency range, a low factor for dissipation, very high surface resistivity, and have insulating capabilities to withstand up to 2,000 volts, depending on coating thickness and the specific Series 100 coating being applied.

Non-Wetting

Series 100 "Infused Matrix" coatings are both oleophobic and hydrophobic, therefore, resist wetting by most liquids. Clean-up is easier, more thorough, and in many cases, reduced or unnecessary.
