b"Harken Materials & PropertiesClear-AnodizedClear aluminum anodizing is an electrochemical process that produces a corrosion-resistant finish. It also hardens the surface, making components less prone to scratches and dents. It is clear because the protective layer isnt thick enough to change the color of the component (though dye can be added). More rigorous anodizing, such as hardcoat, can give components a black or colored hue.Delrin Acetal ResinBlack (white in older blocks) material which excels in small boat and low to moderate-load applications. Delrin acetal resin is used for bearings, sheaves, and sideplates.Hardcoat-anodized Clear-anodizedHardcoat-AnodizedHardcoat aluminum anodizing is an electrochemical process that produces a6061-T6 Aluminum Anodizing Thicknesscorrosion-resistant finish with hardness characteristics second only to diamonds. Harken's hardcoating process is twice as thick as black anodizing to provide extraClear Thickness range protection against scratches, dents, superficial deformation, and corrosion. in inchesBlackHard Lube-AnodizedHard Lube-anodized aluminum includes all the corrosion-resistant propertiesHarken hardcoatof hardcoat-anodized aluminum with the additional benefits of a PTFE coating for a smoother surface and reduced friction0002 .0005 .001 .015 .002Nylatron NylonDurable, lightweight composite material that has high mechanical strength and stiffness, resists static electricity, and has excellent wear resistance.PTFE-CoatedPTFE-coating, along with anodizing, protects aluminum against corrosion by sealing the surface from moisture. It also minimizes friction and gives the component better wear resistance.Stainless Steel17-4 PH Stainless Steel: this alloy is used in gears because it is hardenable to extremely high strengths. 17-4 PH is more corrosion-resistant than any other standard hardenable stainless steel. Delrin316 Stainless Steel: this is a nonhardenable alloy with high corrosion resistance in freshwater and saltwater.XM-19 Stainless Steel: this stainless is highly alloyed, with very high mechanical strength and superior corrosion resistance. Rods and pins in Harken cylinders are made of XM-19 stainless.TitaniumThis lightweight, hard metal has the highest strength-to-weight ratio of any metal. Its corrosion rate is so low that after 4000 years in seawater, corrosion would only have penetrated to the thickness of a thin sheet of paper. Harken uses titanium rollers in V blocks to handle bearing loads.Torlon ThermoplasticExceptionally strong crush/impact-resistant bearing material that withstands heavy long-term use and shock loading. Most Harken hardware that sees extreme loads uses greenish-brown Torlon bearings. TorlonUV-StabilizedUV light photo-degrades composites by breaking their chemical bonds, leaving them weak, brittle, and discolored. This is common in equipment with white bearings. All Harken composites and bearings are naturally UV-resistant or use stabilizers like carbon black.Not UV-stabilized UV-stabilizedFor complete listing, see www.harken.com/glossaryDelrin is a registered trademark of E.
