Parylene

(Pc)
 84 Magnets
<0.05mm Pc, polymere applied in vaccum chamber, optically opaque, surface beneath visible
best none metallic protection against corrosion, hydrophobe, watertight & gastight, non-soluble, barrier against organic & anorganic substances, strong acids & alkaline solution, gas & steam, structure-preserving, low friction coefficient, di-electric, meets MIL-I-46058C, non-toxic, fungus & bacteria tight, bio-compatible, physiologically & toxicologically harmless, anti-allergic
Teflon

(NiTf)
 7 Magnets
>0.02mm NiTf, plastic layer, blue, soft and elastic surface
good protection against corrosion, water-repellent, barrier against organic & anorganic substances, strong acids & alkaline solution, gas & steam, structure-preserving, low friction coefficient, di-electric, mechanically sensitive
Epoxy

(Ep)
 122 Magnets
>0.05mm Ep, plastic layer in dip-coating process, black, soft and elastic surface
good protection against corrosion, water-repellent, mechanically sensitive
Gold

(Au)
 133 Magnets
>0.01mm Ni+Cu+Ni+Au, galvanically applied golden surface, Industry-Gold or 24Karat
best metallic protection against corrosion, very good electrical conductivity, no negative effect at body contact
Silver

(Ag)
 52 Magnets
>0.01mm Ni+Cu+Ni+Ag, galvanically applied silver, soft surface
very good protection against corrosion, very good electrical conductivity, typical black oxid can be removed with cleaning cloth, no negative effect at body contact, pay attention to the right magnet material (max.op.temp.) if soldering is planned
Tin

(Sn)
 7 Magnets
>0.01mm Sn, galvanically applied silver, soft and tight surface
very good protection against corrosion, good electrical conductivity, no negative effect at body contact, pay attention to the right magnet material (max.op.temp.) if soldering is planned
Chrome

(Cr)
 66 Magnets
>0.01mm Ni+Cu+Ni+Cr, galvanically applied dark silver-like, tight and hard surface
very good protection against corrosion
Zinc

(Zn)
 181 Magnets
>0.006mm Zn, galvanically applied blue silver-like, tight and even surface
good protection against corrosion
Nickel

(Ni)
 1570 Magnets
>0.01mm Ni+Cu+Ni, galvanically applied silver or dark silver-like, porose and hard surface
Industrial standard, good work stability, sufficient protection against corrosion in dry ambients, possible allergic reaction on sensible persons
not coated

(Rw)
 245 Magnets
Magnet material grey metallic
acceptable for SamariumCobalt - but no good mechanical protection, not acceptable for Neodymium - oxidation in wet ambients, dissolution in acids, lightly resistant in alkaline suspensions. Sealing neccessary.
