COMPARISON OF 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.
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.
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.
Range: 2500° F
- Depac Metal-Free
Anti-Seize can be used in all applications, is free of any hazardous
metal particles, is nontoxic, and is totally environmentally friendly.
Range: Subzero to 2500° F
