AlloysAluminum, Copper, Stainless Steel

Selected for their resistance to corrosion, tensile and yielding strength, Cometic® alloy materials include Copper, Aluminum and Stainless Steel.

Copper

Copper

The purest grade of oxygen-free copper, C110 Copper features corrosion resistance, ductility, high thermal conductivity, and is not susceptible to embrittlement when heated.

Cometic uses 99.9% pure copper that is tested for uniform flatness to ensure the best possible seal between the head and block. O-ringing is recommended.

Recommended Use: Head Gaskets, Base Gaskets, Exhaust Gaskets

Available Thickness: .005, .010, .016, .020, .027, .032, .043, .050, .063, .080, .094

Stainless Steel 301-1/4 Hard

Stainless Steel 301-1/4 Hard

301-1/4 Hard is austenitic stainless steel that has been cold rolled to increase the strength with a tensile strength of 125,000 PSI minimum and minimum yield strength of 75,000 PSI.

Available Thickness: .012, .0158, .016, .020, .025, .031, .100

Aluminum

Aluminum

Using a solid piece of aircraft grade 6061 alloy aluminum, the tensile and yeilding strength allows our gaskets to be used on high performance applications.

Recommended Use: Head Shim, Base Shim, Carburetor Spacer, Torque Plate

Available Thicknesses: .010, .016, .020, .025, .032, .040, .047, .050, .063, .080, .100, .125, .160, .188, .217, .250, .313, .375, .500, .625
