Quality Coatings of Spokane, Washington is excited to offer Tuffcoat. Tuffcoat combines the hardness and durability of hard anodizing with the lubricity of Teflon. This revolutionary coating allows the use of light-weight, inexpensive aluminum alloys in place of more expensive stainless or hardened steels or hard chrome plated steels. The release properties of the Teflon allow for a myriad of uses. Not only does Tuffcoat provide a slippery, wear resistant finish, it also has a high resistance to corrosion.
Tuffcoat can be applied to most common aluminum alloys. Tuffcoat has been found to extend part performance and life in numerous applications. Some of these include pins, shafts, pistons, gears, pinions, slides, tracks, impellers, volutes, rails, etc., just to name a few. Tuffcoat’s applications are virtually endless. Any situation that needs a hard, slick surface is right for Tuffcoat. Tuffcoat is also an electrical insulator. Tuffcoat also conforms to MIL-A-63576A Type 1.
Tuffcoat’s normal thickness is 0.002 in. on most alloys. Coating thickness can be varied if customers request. Tuffcoat, as with hard anodizing, builds with half of the coating penetrating the original aluminum surface layer and half of the coating building on top of the original aluminum surface layer. In otherwords, 0.001 inches in and 0.001 inches out for a total layer thickness of 0.002 inches. This becomes critical in part design and machining. The engineer must bear in mind that bores will close 0.002 inches in the diameter, studs will grow 0.002 inches in diameter, and part width and length will grow 0.002 inches with a Tuffcoated piece.
