Metal- Free Anti-Seize


Historically there have been three basic types of Anti-Seize on the market:


Copper base anti-seize offers good corrosion protection on all kinds of steel, but not stainless steel. Copper on stainless steel creates an inter-crystaline corrosion, which can make actual stainless steel parts crack and break. This is why the nuclear power plants do not allow copper with any material which comes in contact with the stainless steel parts.
Temperature Range: 2200° F


Aluminum as a base material for Anti-Seize is good for use on stainless steel, but cannot be used on carbon steel, due to the fact that when it comes in contact with an electrolyte it becomes an anode and since this anode is extremely small in volume compared to the large cathode of the steel, it usually deteriorates quickly, leaving no protection at all on the steel surface. Corrosion therefore takes place at a higher rate of speed, as if no anti-seize would have been present.
Temperature Range: 1470° F


Nickel has been used extensively in Anti-Seize materials, because it has good anti-seize and corrosion protection for both steel and stainless steel. However, nickel has been for many years, on the list of carcinogens ( cancer producing products ) and should not be used in applications where nickel based anti-seize is used on materials handled in workshops.
Temperature Range: 2500° F
